Natural river sand takes millions of years to form and is not repleneshible. Because of its limited supply, the cost of Natural River sand has sky rocketed and its consistent supply cannot be guaranteed. Under this circumstances use of manufactured sand becomes inevitable.
of manufactured sand as a replacement of natural sand. The details of these tests are given in the following sections. Workability Tests: a) Slump Cone Test: According to Indian Standard Specifications 1199-1959 This test is performed to check the consistency of fresh concrete. It is a term which is used to define the state of fresh concrete.
In the experiment natural sand was replaced with manufactured sand of the same grading as the natural sand, while keeping all other variables constant. Apart from the control concrete sample which had natural sand all the other samples were treated to 10%, 20%, 30%, 40% and 50% replacement of the natural sand with manufactured sand.
Materials for replacement of sand are. a. Crushed sand (Manufactured sand), rock are crushed to give particle size and grading at par with sand. The replacement can go up to . b.Crusher dust (quarry waste), % finer than 150 micron are a concern, can replace sand to the amount 25%.
