MANUFACTURED SAND FOR CONCRETE

The best fine material for concrete production is cubical sand made from crushed rock. The Barmac Duopactor is a vertical-shaft impactor, which offers considerable flexibility for this process, and has several other advantages. It is used widely in the UK for producing high-quality aggregates and 0-5mm concrete sands; it is also well established for crushing a wide variety of industrial minerals. Availability:

Manufactured sand for concrete. B.P., Hudson. S.l. :

Based on the laboratory test results with full replacement of river sand by Ambo Sandstone Fine Aggregate (ASFA), the mean compressive strengths at 7 th day was 16.61 MPa, while at the 14 th day was 19.62MPa, and at 28 th day was 25.59 MPa. It means at 28 th day; it satisfied the minimum requirement for C-25 grade concrete. Likewise, the cost of production of the fine aggregate of the Ambo Sandstone quarry site is 140 ETB per cubic meter, while the price of river sand
