Strength of cementitious mortars: a literature review with special reference to weak mortars in tension

G.T. Still, (February 2004)

Cementitious materials are commonly used for the construction of low-cost water storage tanks in developing countries. For this purpose an understanding of their properties, particularly tensile, is important.

A literature review is undertaken, starting with factors determining mortar strength. Expressions are quoted for optimum water content varying with determined for each sand:cement ratio; this content will depend on the compaction method being used.

The review is followed by some analytical work based on available data, suggesting that sand:cement ratios of around 6:1 are optimal with respect to materials cost, provided certain strength relationships suggested from existing data hold.
