artificial concrete analytically as well as graphically. The conclusions were made for the understanding the effect of artificial concrete in terms of strength and workability over traditional concrete. Keyword:-Artificial Sand, Concrete, Natural Sand, compressive strength, flexural and tensile strength. 1. INTRODUCTION
A 45 N drop weight was used as the impact load. The number of strikes needed to cause the initial and ultimate failure of concrete samples by dropping a hammer from a height of 457 mm was noted. For the traditional sand concrete, made sand concrete and the best replacement of concrete, tests were carried out and results were presented. IV.
