PROPERTIES OF CONCRETE MADE WITH MANUFACTURED SAND (M- SAND) AS FINE AGGREGATE REPLACEMENT: A REVIEW
Concrete is a composite material constitute of cement, aggregate, and water. About 75 % of the concrete mixture composed of aggregate. Based on the literature It is estimated that the world utilization of sand is more than 40 billion tons per annum, the need for natural sand for concrete production will be high in the future. Many attempts are made to study the effect of partial and full replacement of natural sand by manufactured sand as fine aggregate. The use of manufactured sand in concrete has shown better performance in concrete properties. The properties of Manufactured sand (M-sand) concrete such as workability, compressive strength, flexural strength, split tensile strength, durability and micro-structure are highlighted. From the review of the literature, it can be said that the use of manufactured sand as a fine aggregate replacement will serve as a better alternative for the river sand. The utilization of manufactured sand can help in reducing the pressure on natural resources due to excessive sand mining from river beds.
