A Realistic Evaluation of Permeability and Tensile Strength from Compressive Strength in Cement Sand Mixes

This paper presents output of an experimental research program to relate various properties of cement sand mixes with its compressive strength. Since a designer always knows the target compressive strength, the findings of this paper immediately provide him with a realistic estimate of the remaining important properties of cement sand mixes.This investigation includes cement sand mortars and micro-concretes, each of twodifferent varieties. Cement sand mortars were made of four different proportions whereasmicro-concretes were of two different proportions. Three water cement ratios with varying dosage of super plasticizers were also used for each of the six mixes. The proportion of 1:6 cement sand mortar was studied in further detail by adding water proofing compound (WPC i.e. Impermo) and silica fume in different proportions. The relationships between cylindrical compressive strength, split tensile strength and water permeability have been established.
