CSA A456.2-98 PDF Download

The CSA A456.2-98 standard provides a comprehensive set of test methods for evaluating the physical properties of these materials. The standard is divided into three sections - dry tests, paste tests, and mortar tests - and each section contains multiple test methods and standard practices.

The dry tests section (A1 to A6) covers sampling, testing, and inspection practices, as well as determining the density of cement and fineness by wet-sieving. It also includes a rapid test method to determine the tendency of silica fume to entrain air in mortar or concrete and a test method for verifying sand.

The paste tests section (B1 to B7) addresses mechanical mixing of hydraulic cement pastes and provides test methods for determining normal consistency, time of set using Vicat and Gillmore needles, atmospheric steam expansion, autoclave expansion, early stiffening of cement paste, and heat of hydration.

The mortar tests section (C1 to C8) focuses on mechanical mixing of hydraulic cement mortars and test methods for determining flow, compressive strengths, water retention of masonry mortar, air content, sulphate expansion, sulphate resistance, 28-day activity index for granulated blast-furnace slag-Portland cement, and sulphate resistance of mortar bars exposed to sulphate solution.

Each test method or standard practice includes a scope, referenced documents, summary of the test, equipment and materials required, and step-by-step procedures to follow. These test methods are essential for quality control and performance evaluation of hydraulic cements, supplementary cementing materials, and cementitious hydraulic slag in various construction applications.
