This paper present the physibility of artificial sand in concrete for the purpose of experimentation concrete mixes are design for m20 and m25 grades by 0 to 100 % with increment of 20 % replacement of natural sand by artificial sand. Compressive and tensile test are conducted to study the strength of concrete for above replacement.
They found that using the same amount of cement, water, and sand, but with different types of sand, namely natural medium sand, natural fine sand, and artificial sand (mainly composed of stone chips), the compressive strengths of the three mortar mixtures at 28 days were 48.3 kg/cm2, 16.7 kg/cm2, and 97.4 kg/cm2, respectively.
The replacement of natural sand by artificial sand is feasible for 60% to 80%. It is seen from above studies there is a variation in strength enhancement of concrete made from artificial sand to ...

The construction sector experiences a growing demand for concrete due to rapid infrastructure development. This development accelerates concrete production upwards of 25 million cubic meters each year in Australia [1] as well as leads to massive extraction of natural resources such as natural aggregate. Sand and gravel are the most …
The fineness modulus of sand used in ordinary concrete is 3.7-1.6, medium sand is suitable, and coarse sand plus a small amount of fine sand can also be used, and the ratio is 4 to 1. For natural sand, one fineness modulus can have multiple gradations.
Use of a large quantity of natural sand making an adverse effect on the nature . For a sustainable development, it is necessary to replace a natural sand and cement with artificial sand and high reactive metakaolin respectively. Till the date, the utilization of artificial sand in concrete is 80 % and 60 % in Mumbai and Pune respectively.
In recent decades, the rapid development in China and other developing countries has increased the demand for concrete materials, depleting freshwater and river sand resources and causing environmental issues (Liu et al., 2018; Hossain et al., 2016).To address these concerns, governments have implemented policies to ban river sand …
