Revision of C494/C494M-19e1 Standard Specification for Chemical Admixtures for Concrete


ASTM C494 as well as many other ASTM standards and specifications require the use of ASTM C150 type I or type II cements. In the past 2 years many cement producers have stopped producing C150 type I, I/II and type II cements and started producing ASTM C595 type IL cement. As a result many testing labs do not have access to type I, I/II or type II cement. ASTM C494 is adding language to allow the use of ASTM C595 type IL cement.
