The Impact of Crushed Sand on Fresh Concrete. In its fresh state, the biggest impact of using artificial sand in the concrete mix design is on its rheology. Even when obtaining a good particle size distribution, the crushed sand’s grain shape and the interaction between particles make some types of concrete almost impractical.

Concrete sand consists of granite rock, gneiss, or limestone. This sand has angular granules and works best when mixed with cement. Besides usage in concrete, concrete sand can also be used in bedding pipes. This type of sand is usually crushed in a quarry and filtered severally to remove huge fragments and large rocks.

From technical point of view the rich mixes may lead to high shrinkage and cracking in the structural concrete, and to evolution of high heat of hydration in mass concrete which may cause cracking. In this study, we have used grit and crushed sand for the design mix and found the characteristic compressive strength at 3,7 and 28 days respectively.

Concrete Sand. Concrete Sand from Southern Crushed Concrete is a fine aggregate that is used in the production of concrete or mortar. Concrete sand is crushed in a quarry then filtered to ensure no large rock fragments are left behind. When mixed with cement and water, a grout is formed that fills the voids between the coarse aggregate.

The global consumption of natural sand is very high, due to the extensive use of concrete or mortar. The fine and coarse aggregates generally occupy 60% to 75% concrete volume (70% to 85% by mass) and strongly influence the concrete’s fresh and hardened properties. Now a day’s sand is becoming a very scarce material. Natural sand deposits are being depleted and causing serious threats to
