Investigation the possibility of supplying sand of Silica resources Hormozgan province for use in cement industry

Cement production in our country is increasing day by day. Cements control of production to be standard, not hidden from anyone. Now the combination of silica sand imported from Germany and cement production, concrete preparatio and compressive strength and flexural tests conducted on concrete compared with the standard resistance and will be acceptance or rejection. Due to the existing index of silica has been prepared in several region of Hormozgan (region Hajiabad) necessary samples (5 samples) of various outcrops of silica. The sample is placed on chemical analysis of silica and other elements were determined. Also, in order to identify minerals and to determine fracture and …, initial sample preparation and thin sections were studied microscopically. The sample was selected according to preliminary studies. These samples were crushed and then grain classification. Three samples of silica sand inside and The German standard sand molded and the standard procedure of choice, Compressive and flexural strength of concrete produced, was measured. Comparison of the concrete compressive strength and flexural provided with The silica interventions The amount of compressive strength and Made of concrete flexural With standard sand (German) and Nyzmqays.h other profile appearance and Standard of physical, the sample More appropriate was selected and suggested.
