Study Of Artificial Sand as Fine Aggregate For M-20 Manufactured Concrete in High Strength Construction

Abstract

Concrete is versatile material of construction everywhere the globe. The natural sand is widely used as a fine aggregate. Due to the large demand the resources of natural sand are almost exhaust hence to meet demand of fine aggregate it has been impose to use artificial sand to keep the quality of concrete intact with artificial sand there is need to study properties of concrete by replacing natural sand with artificial sand. Primary aim is that to low the cost of construction by use of artificial sand aggregates. Secondary aim is to replace successful natural sand by artificial sand aggregates. To get optimum compression strength of concrete by the used of varied proportion of natural sand and artificial sand aggregates. In this project compressive strength of concrete have been studied by replacing natural sand with artificial sand with 25%,50%,75%,100%. Out of these better mix proportion is identified on the basis of compressive strength.  It has been found that with use of artificial sand the workability of concrete reduces drastically with intern reduces the compressive strength of concrete due to poor compaction. It has been found that concrete with replacement 75% of natural sand with artificial sand gives better result as compare to concrete with natural sand.
