A Comparative Study of Compressive Strength of Concrete with Different Types of Sand in Different Periods of Time

Abstract

Concrete is a mixture of cement, sand and Brick chips in some specified proportion which is generally used for R.C.C and C.C. In first case of the Concrete compressive loads such as the load of the wall above it, therefore it is very much necessary to test the Concrete for its compressive strength. This paper discusses the variation of Concrete compressive strength after 7, 14, 28 days with different types of sand (Local sand, Sylhet sand. In the experiment, 30 Cylinder specimens of 4 inch diameter by 8 inch height were tested to identify the compressive strength of Concrete using universal testing machine (UTM). In this experiment, curing process is used to increase the strength of Concrete cylinder. Curing process must be followed to achieve desired concrete properties. Curing is necessary to ensure that the concrete will have sufficient moisture available to develop required properties. The results show that the compressive strength of Concrete sylhet sand is higher than that of the local sand. The difference in compressive strength of Concrete tends to be greater as the difference in sand fineness increases.
