Curing was done (1 ) in a damp room, (2 ) by water-spraying, (3 ) with saturated steam, and (4 ) by the application of impermeable surface membranes. Internal temperature rise caused by hydration of aluminous cements does not impair strength. The only requirement for satisfactory cur ing is the retention of moisture within the concrete. Properly selected organic resin or asphalt membrane coatings are economical and superior in performance to water-spray curing, provided they have lo w water-vapor permeability, adhere to moist refractory concrete, rapidly form films and dry, and are free from deleterious substances. Curing with membrane coatings has been used successfully for eight years in large-scale refinery operations. Curing Refractory Castables: It Isn't the Heat, It's the Hum idity J. F. WYGANT and M. S. CROWLEY Research and Development Dept., American Oil Co., Whiting, Ind. >o D ue traditional method of curing troweled or pneuatically placed refractory castables is frequent spraying ith w ater from about (i hours after placement to about 24 mrs after placement. I t is the only m ethod generally recnmended by refractories manufacturers. This procedure is stly and sometimes unreliable. Laborers must be employed r several consecutive shifts to do the spraying. Scaffolding nnot be removed, and vessels or furnaces cannot be closed ), until the spraying ends. In many locations the castable inaccessible for repeated spraying. A less costly and more liable curing method was desired. The exclusive use of water spraying has been justified on vo bases. One is the need to keep the exposed surface the castable damp, so th at moisture will be available connuously for the hydration of the cement. This need for oisture has been confirmed.1 The other basis rests on the liefs th a t tem peratures much above 90F during hydration use low strengths, and th at the cooling effect of the water ray prevents temperature rise in the castable during hvdram. The former belief was reinforced by th e ` work of ansen and Livovich,5 in which castable refractory materials Te preheated, mixed, and cured at tem peratures from .50 to UF. They found reduced strengths after curing a t 1()0C id 110F, and interpreted them to show th a t curing tem pera res above 90F caused loss of strength. U nfortunately, Presented at the Sixty-Fifth Annual Meeting of The American ramie Society in Pittsburgh, Pa., May 1, 1963 (Refractories vision, N'o 25-R-63I 1 Venable, Jr., "Erosion Resistance of Ceramic Materials r^ B i n i Refinery Applications," Am.

The consequent reduction of strength could have been caused by the increased water :cement ratio rather than by the increased curing temperatures. However, in field installations. Cook et al.3 observed no detrimental effect when castable temperatures were allowed to rise due to retained heat of hydration of the cement. Most types of aluminous cements have high heats of hydration. It appeared reasonable, in view of Venable's work,1th a t strengths would be reduced if the retained heat of hydration caused substantial drying of a castable. The evidence was not convincing that elevated tem perature by itself was harmful, if drying could be prevented. This in vestigation had two purposes: to determine whether tem peratures caused by heat of hydration were harm ful when drving was prevented; and, if not, to develop simplified curing methods. Experimental The tem perature rise, due to the heat of hydration, was measured bv placing thermocouples in a freshly molded castable. Slab specimens were formed by tam ping the castable in molds a t a stiff plastic consistency. Two slal>s were made, 12 by 12 by 3 in., representative in thickness of many refinery applications. The castable was a highstrength commercial product containing about 25 wt% aluminous cement and 75 wt%, calcined flint c la \. Its density after heating a t 1I)()()F was 12S to 130 lb cu ft. The molds were insulated on five sides with 2 in. of polystyrene foam, leaving a 12 bv 12 in. face exposed. One slab was cured in a damp room, a t about 96% relative hum idity and 80 F. The other was cured in the open at 50% relative humidity and 75F, the exposed face being coated with a 1 j* in. layer of asphalt mastic. Another slab of the same material. IS by IS bv s in , was insulated similarly and cured under a in 1 layer of asphalt mastic. The mastic was a high-viscosity dispersion of asphalt and mineral pigments in a hydrocarbon solvent, sold as a vapor barrier coating' To obtain a yet larger tem perature rise, an 18 in. cube was molded of a 60 lb/cu ft insulating castable. This castable contained about 50 w t% pure calcium alum inate cement and 50 w t% perlite. The exceptionally high heat of hydration of the cement, together with the low thermal conductivity and low volumetric heat capacity of th castable, was expected to cause very high temperatures during curing. The mold was insulated on all sides with 2 in. of polystyrene foam. Therm o couples were inserted as the castable was placed at plastic consistency. Compressive strengths were determined on 2 in. cubes cut from the large cuire. To confirm the results of these tests, and to evaluate steam curing and other types of organic membranes, 13 additional series of tests were made. Each series included three to eight castable slabs made on a single day. The castable used in each series was mixed and split to yield uniform samples. Nominally equivalent high-strength castables from four m anufacturers were used. Day-to-day variations in ambient tem peratures, tap water tem peratures, and humidity were unavoidable, and there was a practical lim it on the number of slabs to be handled simultaneously. The series arrangement provided identical ambient conditions for all the specimens in a given series. W ater spray curing, simulating conventional practice, was done autom atically in a cabinet equipped with spray heads, timers, and solenoid valves. Slabs, in their molds, were placed vertically in the cabinet within 30 minutes after form ing, and the door was closed to cause the relative humidity to build up. Spraying began 6 hours after forming. A 30 second sprat- period followed at 30 minute intervals for 18 hours. Damp room curing, the usual standard laboratory method, was done in a room at about 96^. relative humidity and 80F. Specimens were placed in the damp room shortly after forming and left there for 24 hours. Steam curing was accomplished by building a hollow cube of 12 by 12 in. concrete panels. The specimens in their molds constituted one or two sides, with their exposed faces inward. Com ers were sealed, and exhaust steam a t 5 to 15 psig was introduced, beginning 2 to 4 hours after forming and con tinuing for the rem ainder of the 24 hours after forming. The exhaust steam was ordinarily saturated, but up to about 10F of superheat occurred occasionally. Some specimens were cured in open laboratory air, at about 75F and 50c'f relative hum idity, with no measurable air movement. For membrane curing, organic films were applied to the exposed surfaces of some specimens. Molded slabs were cured in this wav in the laboratory for 1 day, then were removed from the molds for drying. The same asphalt mastic used for the earlier temperature tests was applied to a numlier of slabs by troweling, about w in. thick, 30 to 60 minutes after the concrete was placed. O ther membranes also were used. Molten paraffin was brushed on one slab. (Paraffin solutions proved impractical. ) Four commercial concrete curing compounds, solutions of resins in hydrocarbon solvents, were applied by spraying. Two of the resin compounds contained red dyes, but no jrigment. The other two contained white titania pigments. Two w ater emulsions of resins were applied by spraying. These were a styrene copolymer and an alkvd resin emulsion, stabilized and pigmented in commercial coating products. Brief experiments, but no strength tests, were made with a water emulsion and a ketone dispersion of asphalt. Several tests were made with membranes of a special asphalt cutback, containing appropriate additives and fast drying solvents, developed for this use in cooperation with a vendor. In most of the tests, only 12 by 12 by 3 in. slabs were formed, either by tamping a plastic mix or by use of a Cement Gun Co. Size 00 cement gun. Tamping mixes were placed a t a uniform stiff ball-in-hand consistency. Gunning was done so as to obtain the temporary water sheen recently de scribed as indicating the optimum water content.4 After curing, these slabs were cut into two 12 by 6 by 3 in. specimens, each of which was broken as a simple beam to determine modulus of rupture. To measure compressive strength, 2 in. cubes usually were cut from the broken halves and crushed. In a few cases 2 in. cubes were molded sep arately to determine compressive strength. In all tests, strengths were determined after 24 hours of curing, 1 to 3 d ay s of air drying, and 24 hours a t 220F. In some tests, duplicate slabs were heated to 1000F, after drying a t 220F, before testing. Results Effects of Temperature Table I shows the temperatures developed in 3 and 8 in. slabs of dense refractory concrete when the concrete was not cooled by spraying with water. By analogy with the 3 in. slabs, the internal temperature in the 8 in. slab probably was about 165F. The similarity between center and bottom face tem peratures in the 3 in. slabs is evidence th a t heat loss from the insulated sides of the molds was insignificant. Each slab therefore was approximately the equivalent of a semi-infinite slab, twice as thick, with both surfaces exposed or with the back surface in contact with an uninsulated vessel shell. The tem perature was slightly higher in the surface-sealed 3 in. slab than in the unsealed, probably be cause of the insulating effect of the asphalt mastic. In Table II, Series 2, 6, and 7, direct comparisons can be made between 3 in. slabs cured by water spraying and slabs th a t were not water sprayed. The strengths with dam p room curing generally were about the same as those with water spray curing. Asphalt mastic membranes gave results similar to water spraying in Series 2 and 6; in Series 7 asphalt membranes were superior. The small cooling effect of w ater spraying a t 30 minute intervals did not lead to increased strengths. In fact, tem peratures in the mem brane-cured slabs m ust have approached 120F, from re tained h eat of hydration, bu t did not adversely affect strengths.

C and D were castables would have to be about 6 in. thick to reach this temperature during curing. Effects of even higher tem pera ture are shown in Table III. The tem perature of the large insulating castable cube reached the atmospheric boiling point of water, and IS hours after molding the cube was still steaming vigorously. Because of the high absorption of the perlite, the initial water content was high and only a small p art of the water was driven off. In spite of the high curing tem perature, strength was considerably higher than usual. Results with the IS in. cube are confirmed bv those with steam curing in Series 7. S, and 9. Table II. The castable tj^ ^ r a tu r e s during steam curing must have approached In these series, strengths of steam-cured slabs r a ^ ^ n from about 20 to 80% higher than with water spray or damp room curing. The variability probably was due to varying vapor-tightness of molds. Under favorable con ditions, strength increased with curing at steam temperatures Vo l. 43, No. 1 (1064) Elevated temperatures, even though achieved by ex ternal heating therefore appear harmless. They may even be helpful with respect to strength, if evaporation of signif icant amounts of water is prevented. In plant practice, insulating castable sections 18 in. thick (and probably th in ner) can reach steam temperatures. The usual high-strength dense castables, in thicknesses of 8 to 10 in., would ordinarily reach temperatures not exceeding 165F. New Curing Methods Strengths of eleven series of slabs cured by various methods are summarized in Table II. Direct comparisons are pos sible within each series, but different series cannot be com pared directly because of differences in m aterials and place ment conditions. However, either damp room or w ater spray curing can lie used as an internal standard, against which other methods in a series can be compared. Damp 3 Table III.

In these three series, the averages of dam p room and spray curing results were used as standards for com parison. In each of the other series, only one of these two methods was included, and it was used for comparison.

But steam curing caused increased strengths, except in Series 1, 2, and 3. The variable effects of steam curing in the first three curing cycles were traced to 5 to 10F superheat in the steam.

A sphalt mastic and paraffin wax membranes, with two ;. exceptions, yielded strengths superior to, or statistically' indistinguishable from, those resulting from damp room curing. These membranes contain thin spots and defects, permeable to water vapor, unless they are applied very ; carefully. Nevertheless, these tests showed the potentially ; excellent performance of impermeable membranes. : The ketone dispersion of asphalt (not shown in Table IV) | showed no advantage over the asphalt mastic except the | absence of low flash point solvents. Coatings of asphalt f emulsion (not shown), and of alkyd and styrene emulsions, f are not sufficiently impermeable to water vapor. The high | water vapor permeability of similarly formulated water- f base paints is well known in paint technology'. I The resin solution curing compounds gave uniformly good results. This was also true with the asphalt cutback curing compound, as shown in Tables II and IV, Series 11, and in Table V. The average results of all m em brane curing tests were superior to those of damp room and/or spray curing. The results with resin solutions and the asphalt cutback in Series 10 and 11 average 21% higher than with spray curing. The tests in Tables II and IV were completed in 1955; those in Table V in 1956. Hundreds of additional test slabs, made and cured with membranes since then, confirm the results shown here. A considerable number of 2 in. cubes and 2 by 4 in. cylinders also were made during the same period, and cured bv the use of membranes under the sem iadiabaticf conditions recently described by Treffner and Williams.*/ The tem peratures reached were like those in Table I, and the.- strengths were normal. \ Practical Applications | Several petroleum refineries have been using m em b ran e curing, with selected resin solution and asphalt cutback/ membranes, since early 1955. It has been eminently sue-, eessful in curing refractory castable vessel linings and filler,sections up to 12 in. thick. Hairline surface cracking, often observed after water spray curing, usually is absent. Cured surfaces are notably hard. Lining service has been good. Substantial savings have been made by the elimination of. two or three shifts of water spraying labor. Earlier start-/ ups are perm itted by removal of scaffolding as soon as the membrane is applied.

Whenever more refractoriness and improved P.C.E. are needed, the high alum ina content and cry stal line strength of Carolina Mullite or K yanite make it the tool for the job. W hen more therm al shock resistance is required, the Ceram ist can look to Commercialores' K yanite or M ullite to solve his problem. For predictable control over fired body dimensions, simply add a known percentage and grain size of Carolina K yanite to the mix. Its expansion, when fired, off sets the shrinkage of other m aterials. All types of refractories, sanitary ware, wall and floor tile, porcelains, precision casting molds, are some of the m any products which now have better profit pictures due to Carolina K yanite or M ullite.
