This part of BS 1881 describes sampling procedures, treatment of samples and analytical methods to determine the cement content, aggregate content, aggregate grading, original water content, type of cement, type of aggregate, chloride content, sulfate content and alkali content of a sample of concrete.<\/p>\n

The procedures are applicable to concretes made with CEM I cements and, in favourable circumstances, concretes containing ground granulated blastfurnace slag (GGBS).<\/p>\n

This part of BS 1881 does not cover the analysis of concretes made with other cements and the determination of fly ash content.<\/p>\n
