Pulverized Silica
A. GENERAL
1. Description
Pulverized silica, for purposes of this specification, consists of a high purity grade of natural occurring crystalline sand or silica which has been subjected to grinding and classification processes in order to control its fineness. In some cases it may be necessary to wash the sand or silica in order to improve its purity and color. The re fined pulverized silica shall be white to light gray in color.
B. USE
Pulverized silica reacts chemically with free calcium hydroxide formed during high pressure steam curing of Portland Cement.
C. LOT SIZE
For sampling and inspection purposes, a lot shall be defined as the quantity of pulverized silica shipped in a single carrier, or in one day.
D. REQUIREMENTS
1. Special
1.1 Initial Approval
All pulverized silica suppliers shall be approved in writing by the Technical Services Manager - Materials of Certain-teed Asbestos and Plastics (CAP) Division. Any change in the source of the silica or in its processing by an approved supplier must be authorized in writing by the Technical Services Manager - Materials before the end product may be supplied to CAP Division plants.
