Erosion of rocks produce particles of stone, gravel, sand, silt, and clay. recycled concrete, or crushed waste concrete, is a feasible source of aggregates and an economic reality, especially where good aggregates are scarce. conven-tional stone crushing equipment can be used, and new equipment has been developed to reduce noise and dust.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.For low-strength concrete, below 10 stone powder content is hard to pumping. pump resistance decreases by stone powder content increasing. this is because more stone powder provides better lubrication. crushed sand angularity is weaken. at the same time, larger mb value leads to better pump performance by increasing cohesion.

By means of laboratory experiment, pump performance of crush sand concretes with different stone powder content and methylene blue value are measured. more stone powder provides better lubrication and better pump performance on low-strength concrete. paste viscosity increases by increasing stone powder in high- strength concrete and lead to poor pumpsand machine.

Quality of sand is as much of importance as other materials for concrete. aggregate most of which pass through 4.75 mm is sieve is known as fine aggregate. fine aggregate shall consists of natural sand, crushed stone sand, crushed gravel sand stone dust or sand machine.
