Factors Affecting Cement Paste When Used As A Binding Agent With Rice Husks

Abstract

Cement is one of the most widely used binding agent especially in the construction of buildings. The most commonly used type of cement is Portland cement. Portland cement is very effective in concrete works, mortar, block moulding of different types etc. unfortunately cement pest is affected by a number of factors including acids, sulphates etc. The study revealed that cement is affected by calcium chloride, chloride suphate, magnesium and sodium salt. These chemicals attack and destroy the binding power of cement. “If a salt looses its savour, how shall it be salted? It is therefore good for nothing but to be cast out and to be trodden under foot of men” – Mathew 5:13”.
Also the study revealed that cement retarding sulphate and acid are presented in clay, brick, soil and ground water. To remedy the situation recommendations were made on how to overcome the problems.
