Properties Of Concrete By Replacement Of Natural Sand

2019-7-1  Replacement of natural sand by 60% artificial sand results in producing the concrete of satisfactory workability and strength properties. It is also possible to minimize the area of surface cracks of concrete, thus achieving the durable concrete. However, for more than 60% replacement of natural sand by artificial sand causes reduction in compressive strength of concrete mixes with increase in the area of

M. Sand: An Alternative to the River Sand in Construction ...

2018-5-12  Sand is being used as fine aggregate inconcrete making and is preferred as fine aggregate. It is mostly mined from the river beds and indiscriminate mining of sand has reportedly causing damages to the environment. We also see that dependency on this source has led to high material costs also. Now there is high scarcity of natural sand. Due to this shortage of good quality natural sand and heavy dependency on this, for concrete manufacturing, there has been seen usage of poor quality natural sands for construction. Thus it becomes almost obligatory to find alternatives to natural sand and evaluate these alternatives for use in concrete production. Out of the many available alternatives, crushed stone sand has emerged as the most easily available material. This material is available at all the crushing units as a by-product during production of 20mm and 10mm size aggregates. Another form of crushed stone sand is manufactured sand (M sand), which is better in terms of quality and fulfils the requirements of suitable material for use in concrete. M sand is manufactured by any of the methods- by crushing of coarse aggregates (20mm 10mm) in separate sand

Mechanical and Durability Properties of Concrete Made with ...

River sand is one of the main ingredients used as a fine aggregate in concrete production. A rising demand for construction material has led to the overexploitation of river sand, and this overexploitation has led to harmful consequences like increase in river bed depth, lowering of the water table, and intrusion of salinity into the river.
