This report covers compliance data gathered for RII-77, a Portland cement grinding aid, in compliance with ASTM-C-465-74, "Standard Test Method for Processing Additions for Use in the Manufacture of Hydraulic Cements".

The pairs of cements for this evaluation were ground at the Midlothian, Texas plant of Texas Industries, Inc.; the Artesia, Mississippi plant of United Cement Company; the Harleyville, South Carolina plant of Santee Portland Cement Corporation; the Chanute, Kansas plant of Ash Grove Cement Company; the West Des Moines, Iowa plant of Penn Dixie Industries, and the Keystone Portland Cement Company plant at Bnth, Penna.

The cement samples were all shipped to ROAN INDUSTRIES, Inc., 439 South Bolmar Street, West Chester, Pa. for testing.

The chemical and physical results were developed by Ambrie Testing, Inc., and are shown on the enclosed tables. Greenwood Laboratories was responsible for the development of a test method for determination of the percent of RII-77 in Portland cement.

It is believed that these data are sufficient to comply with ASTM-C-465, and, consequently, the additions requirement of ASTM-C-150, "Standard Specification for Portland Cement".

Dear Sir:

The purpose of this letter is to certify that on April 13, 1977, Type III cement containing Roan Industries, Inc.'s cement grinding aid RII-77 was ground at Ash Grove Cement Company's Chanute, Kansas, facility.

The cement produced complies with ASTM specifications C-150 and sampling procedures for both the cement containing RII-77 and the control cement containing W. R. Grace's HEA-2 were in accordance with ASTM specifications C-465.

RII-77 was added to the finish mill system in a solution containing about 13% active material.

Both RII-77 and HEA-2 were added at an approximate rate of 0.04%.

 

Yours truly,
