May 01, 2020 Abstract. This study uses silica sand, which has a high SiO 2 content and micron size as a substitute for normal sand with control specimens with compressive strength of f c ′ 45 MPa. Two types of silica sand gradations were used, namely 80-100 mesh(0.177 mm ─ 0.149 mm) in size and 325 mesh (0.044 mm) in size from Bangka as the fine aggregate.
Abstract The use of alternative aggregate like silica sand is a natural step in solving part of depletion of natural aggregates. The investigation on alternative material for concrete making started before half a century. Concrete made from silica sand waste as Keywords: Silica sand, Workability, Compressive strength, Tensile strength
Abstract Silica sand is one of the most common varieties of sand, and it is used in industrial applications throughout the world. The application depends on the purity, grain size and chemical characteristics. In the present study, X-ray, chemical and petrographic analyses were used to study sand deposits from Tabuk area in Saudi Arabia.
Apr 01, 2018 Abstract. The characterization of natural silica from Tanah Datar region has been done due to variation of calcination temperature. Characterization is done using X-Ray Fluorescence (XRF) and X-Ray Diffraction (XRD). The results of the XRF test show that the content of silica
Mar 24, 2014 Abstract. Silica sand, (almost) pure quartz sand, is a valuable and scarce mineral resource within the shallow Dutch subsurface. High-grade deposits are exploited in the southeasternmost part of the country, as raw material for the glass, ceramic, chemical and other process industries. Dutch land-use policy requires that scarce mineral
Abstract The silica sand from Chertala area of Alappuzha district has been reported to be of good quality. Presently, it is mined and transported to destinations inside and outside the State without any processing. A project on beneficiation/value addition of this sand was taken up as
