Abstract :
Cement production in our country is increasing day by day. Cements control of production to be standard, nothidden 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 thestandard resistance and will be acceptance or rejection. Due to the existing index of silica has been prepared inseveral region of Hormozgan (region Hajiabad) necessary samples (5 samples) of various outcrops of silica. Thesample is placed on chemical analysis of silica and other elements were determined. Also, in order to identifyminerals and to determine fracture and …, initial sample preparation and thin sections were studiedmicroscopically. The sample was selected according to preliminary studies. These samples were crushed andthen grain classification. Three samples of silica sand inside and The German standard sand molded and thestandard 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 Theamount of compressive strength and Made of concrete flexural With standard sand (German) and Nyzmqays.hother profile appearance and Standard of physical , the sample More appropriate was selected and suggested.
