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 Mix Design Using Crushed Sand  Concrete ,CONCRETE MIX DESIGN USING CRUSHED SAND. The process of selecting suitable ingredients of concrete and determining their relative amounts with the objective of producing a concrete of the required, strength, durability, and workability as economically as possible, is termed the concrete mix design.Mix proportioning and performance of a crushed,Crushed stone sand has been identified as a potential substitute material for natural sand in making good quality concrete. The main objective of the present investigation is to determine an adequate mix design method and evaluate engineering properties of crushed limestone sand concrete mixtures in both the fresh and hardened sates.

Read MoreConcrete mix design is the process of finding the proportions of concrete mix in terms of ratios of cement, sand and coarse aggregates. For e.g., a concrete mix of proportions 1:2:4 means that cement, fine and coarse aggregate are in the ratio 1:2:4 or the mix contains one part of cement, two parts of fine aggregate and four parts of coarseNew type of crushed sand to replace natural sand in,,This also includes developing a new concrete mix design philosophy that is adapted to crushed sands with specially engineered properties that are different from those of natural sands. The latter is what has been chosen as the philosophy of the new approach of crushed sand production currently under development within the COIN project.Crushed Sand vs. Natural Sand: Make the Right Choice!,Hence, effects the assumptions of concrete mix design and quality of concrete. c) Concrete Strength The compressive strength as well as the flexural strength of concrete made from Crushed sand are higher than natural sand.
