Studies on Strength and Durability of Concrete Made with Manufactured Sand

Many academics throughout the world have been interested in the use of artificial sand in concrete. The growing demand for fine aggregate for the needs of building is greater than the supply of limited natural sand that is currently available. It is suggested that the physical characteristics of naturally occurring river sand and synthetic sand be compared M sand . The M30, M40, and M50 mixtures were the subjects of the current study. By varying the relative amount of M sand from 0 to 100 , the modulus of elasticity MOE was assessed. The abovementioned mixes were also tested for sorptivity and impact resistance to determine the ideal percentage of manufactured sand. Moreover, microscopic analyses using electron dispersive spectroscopy EDS and scanning electron microscopy SEM were carried out. With an increase in mix grade, MOE and resistance to impact loading both improved. Yet, as concrete grade and M sand content increased, sorptivity was found to decrease. Also, a comparison between experimental MOE values and IS code results was done. According to microscopic investigations, M sand has an angular and rough surface in comparison to natural sand, which is thought to be the cause of the materials improved MOE and impact resistance as well as its decreased sorptivity.
