CONCRETE MIX DESIGN USING CRUSHED SAND. ... The results of mix design indicate that crushed sand can also make as good a concrete as that made of natural sand.The compressive strength obtained is same as of normal mixes.In fact use of crushed sand will become inevitable in near future because of dwindling sources of natural 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. ...
