The strength of concrete is controlled by the proportioning of cement, coarse and fine aggregates, water, and various admixtures. The ratio of the water to cement is the chief factor for determining concrete strength. The lower the water-cement ratio, the higher is the compressive strength. The capacity of concrete is reported in psi – pounds ...

[1] conducted tests on masonry prisms and concluded that the compressive strength of the Soil-Cement Block masonry prism decreases as the mortar bed joint thickness is increased and the reduction in compressive strength is about 16% for a fivefold increase in bed joint thickness from 6 to 30 mm. Rehman . and Ueda [2 ...
The compressive strength of brick or structural clay tile is an important material property for structural applications. In general, increasing the compressive strength of the unit will increase the masonry assemblage compressive strength and elastic modulus. However, brick and structural clay tile are frequently specified by material standard ...
