What is Study of concrete mixes (M20 and M30) with optimum cement consumption using 100% crushed sand and effect of silt content in the crushed sand on strength and workability of the concrete about?

Now a day, as there is scarcity of natural sand, it is essential to replace it with some other constituent to make concrete. The natural sand is now being replaced by crushed sand (crushed sand is obtained from quarry by crushing stones to required size). Civil engineers and contractors are using crushed sand for making concrete as river sand is now not available and comparatively the crushed sand is cheaper. However, it is imperative to verify its effects on strength, workability and cost of concrete but before using crushed sand for making concrete. The civil engineers and contractors in rural parts of western Maharashtra region have strong belief that the use of crushed sand for making cement concrete results in increase of cement consumption per cubic meter of concrete. Also, the percentage of fine particles (less than 150 mm termed as silt) in the crushed sand considerably affects the strength of the concrete. This paper represents the experimental study carried out to design the concrete mixes for achieving the desired strength at optimum cement consumption. Also, the effect of percentage silt content in the crushed sand, on the strength of concrete was studied. After the exp
