Note: A newer version of this document exists. This document was replaced by 225R-16.

Because cement is the most active component of concrete and usually has the greatest unit cost, its selection and proper use is important in obtaining blance of properties and cost desired for a particular concrete mixture. Selection should take into account the properties of the available cements anf the performance required of the concrete. This report summarizes information about the composition and availability of commercial hydraulic cements and factors affecting their performance in concrete. The largest part of this report covers the influence of cement on the properties of concrete. Cement storage and delivery, and the sampling and testing of hydraulic cements for conformance to specifications are reviewed briefly. This report help users recognize when a readily available, general purpose (ASTM C 150 Type I) cement will perform satisfactorily, or when conditions require selection of a cement that means some additional requirements. It will also aid cement users by providing genreal information on the effects of cements on the properties of concrete.
