you use course sand in concrete mix you rarely use building sand anyway as it comes as ballast to buy, sharp sand is more for screeds and rendering. You never use building sand with a concrete mix , it will make concrete weak . always use sharp sand as it it more coarser and make concrete stronger and give a better colour when dry.

The study investigates the use of crushed rock sand as viable alternative to Natural River sand that is being conventionally used as fine aggregate in cement concrete. Various mix designs were developed for different grades of concrete based on IS, ACI and British codes using Natural River sand and crushed rock sand. In each case, the cube compressive strength test, and beam flexure tests were

Sand is a primary component for making concrete, mortar and plaster, so you shouldn’t be surprised to find they make up the buildings around you. Sand in construction should generally be clean and free of stones and other impurities. To ensure there is no excess clay, silt and dust, you can use washed sand if this is a requirement in your

It was observed that with use of crusher dust at all replacement levels, the workability of concrete was reduced from 1-6%. From the test results, it was observed that the replacement of natural sand by crusher dust increased the compressive strength of concrete by 5-22%. It was also found that amongst all the mixes, the highest compressive

As the supply of suitable natural sand near the point of consumption is becoming exhausted, the shortage of good natural sand for concrete production is facing challenges. The construction industry has a huge need to solve this challenge. This is also resulting in poor qualities of sand, particularly containing silt. They need to solve this challenge by using crushed sand in construction works

The first step to recycling old concrete is to use industrial crushing equipment in order to break up the original structure. Next, the broken up concrete is run through a secondary impactor. After being crushed to an even smaller size, the crushed concrete is then screened so that dirt and other foreign objects can be removed. After this step, the concrete is separated out by size.

Answer (1 of 2): Absolutely you can that is exactly what aggregate is, however keep in mind on larger jobs using your own aggregate may lead to inconsistent properties in the concrete strength and workability.

Manufacturing of Sand process involves three stages, crushing of stones in to aggregates by VSI, then fed to Rotopactor to crush aggregates into sand to required grain sizes (as fines). Screening is done to eliminate dust particles and Washing of sand eliminates very fine particles present within. The end product will satisfy all the requirements of IS:383 and can be used in Concrete

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.
