This Singapore Standard describes the sampling procedures, treatment of samples, and analytical methods to be used on a sample of concrete to determine the cement content, aggregate content, aggregate grading, original water content, type of cement, type of aggregate, chloride content, sulphate content, and alkali content.
The procedures apply to concretes made with Portland cements and, in favourable circumstances, containing ground granulated blastfurnace slag.
The analysis of concretes made with other cements and the determination of pulverized-fuel ash content are outside the scope of this standard.
