Abstract:

The variation in weight of concrete cube with water cement ratio, mix design and cube size (150mmx150mmx150mm), were tested at Quality Control Lab for research work. The cube was casted at different location in India and was tested at different place around different location in India. When the cube was weighted for the 7days and 28 day test compressive strength of differently casted cube. It was found that variation in concrete cube weight found to be varying from place to place and location in India. After Sieve analysis of coarse aggregate, it was also found that variation in Fineness Modulus of coarse aggregate varied for different location. The variation in Fineness modulus increases volume of coarse aggregate and increases in weight of concrete cube. If the fineness Modulus is constant, the volume of coarse aggregate increase with size of the aggregate, or with the decrease in surface area of the coarse aggregate The main cause in variation in weight of cube found to be specific gravity of Coarse Aggregate. It plays an important role in weight of concrete cube and specific gravity of an aggregate is considered to be a measure of strength or quality of material and specific gravity test helps in identification of stone. Hence we can say that Specific gravity of Aggregate varies at different location in India and weight of concrete cube varied at different location. We can say that weight of cube plays an important role in determining the quality of concrete and compressive Strength of cubes
