Effect of use of Silica Sand as Fine Material in ConcreteSilica Minerals Education Coalition

investigation on alternative material for concrete making started before half a century Concrete made from silica sand waste as fine aggregate was studied for workability compressive strength Split tensile strength and Flexural strength Further study of its durability will ensure greater dependability in its usage So here in this project Silica sand had been used as replacement of fine Fumed silica is used as a filler in the cement and refractory materials industries as well as in heat insulation and filling material for synthetic rubbers polymers and grouts Silica is used in ceramics and in making
