Experimental Study on Strength of Concrete by using PS Sand as a Fine Aggregate

Concrete is considered to be the most widely used and versatile material of construction all over the world. In recent years, concrete technology has made significant advances which have resulted in economical improvements in strength of concretes. This economic development depends upon the intelligent use of locally available materials. One of the important ingredients of conventional concrete is natural sand or river sand. Scarcity of good quality Natural River sand due to depletion of resources and restriction due to environmental consideration has made concrete manufactures to look for suitable alternative fine aggregate. One such alternative is “Manufactured sand�. Because of crushing quarries and converting them as fine aggregates, demand for coarse aggregates also increases. To meet this demand, another alternative to river sand is PS Sand (Processed Slag Sand) which can be used as fine aggregates in manufacturing concrete. An attempt has been made in this study to determine the compressive strength of M20 grade concrete using PS sand as fine aggregate.
