1. Introduction. Concrete is an important and most commonly used construction material. because of its versatile properties. But now days due to scarcity of natural sand, hazardous environmental impact due to depletion of river sand and administrative restrictions, cost of natural sand has increased.

Concrete Ingredients Calculation. For Cement, Sand and Coarse Aggregate. This is a Volumetric Calculation. Assuming we need 2 m 3 of concrete for M20 Concrete Mix, (Mix Ratio, M20 = 1 : 1.5 : 3) Total Part of the Concrete = 1+1.5+3 = 5.5 Parts. Therefore, Cement Quantity = (Cement Part / Concrete Parts ) * Concrete Volume

Natural sand is depleting at a very fast pace and efforts are being made to conserve it. The major solution to this problem is to use manufactured sand produced by crushers such as those provided by PROMAN. Manufacturing concrete sand is proving to be the best solution that balances the demands for environment protection and higher economic growth.

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.

This is because a high fines content in natural sand usually indicates increased silt, clay or shale concentration, which is detrimental to both fresh and hardened concrete properties. In crushed sand, the presence of these contaminants is rare (at least in Scandinavia) and some level of fines would normally increase the content of filler

Sahu et al. (2003) observed that concrete made using crushed rock sand attained the comparable compressive strength, tensile strength and modulus of rupture as the control concrete. Sahul Hameed and Sekar (2009) concluded that the compressive strength, split tensile strength and the durability properties of concrete made of quarry rock dust are nearly 14% more than the conventional concrete.

Hi, Would like to know if there any problems using crusher dust for my concrete instead of sand and gravel, the crusher dust has a fair bit of powder so it mixes ok but i''m want to use it for footings for raised floor of ganny flat, was going to use mix of 4:1 have used it for chooks pens etc and seems alright but don''t know how strong it is to use for house footings. thanks Rick
