Behaviour of cement concrete under common salt solution both under hydrostatic and atmospheric pressures

Abstract

As a part of study of durability of cement concrete in sea water, its behaviour in common salt solution, under large hydrostatic pressures is studied employing accelerated testing techniques such as use of small-sized specimens and increased concentrations of sodium chloride in the curing agent. The effect of common salt is brought out by studying scanning Electron Micrographs and X-ray diffraction patterns and properties such as compressive strength, tensile strength, modulus of elasticity, permeability, pH value and ultrasonic pulse velocity. Pressure produces accelerated effects of deterioration.
