synthetic sand in conrete manufacturing
Use of Manufactured Sand in Concrete and
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 sandimportant Very fine sand is not recommended for concrete purpose The fines content in the sand below 600 microns should be about 30 to 50 % This will be a ideal sand for concrete work as well as masonry and plaster work At present it is generally observed that the fine content in river sand below 600 microns are very less:: ARTIFICIAL SAND
