Experimental Research on the Strength of Concrete for Local Cement with Various Replacement Materials

The main purpose of this paper is to study the effects of "Various replacement materials for cement in concrete strength. Materials used in this research are abundant in Mandalay, Myanmar. In this paper, the chemical composition and physical properties of AAA cement is analysed. Cement replacement materials used in this research are blast furnace slag powder which is obtained from iron and steel industry from Mandalay Industrial Zone, fly ash, and granite quarry dust which obtained from BaeLin, KyaukSe. The physical properties of cement, blast furnace slag powder, fly ash and granite quarry dust, sand and aggregate are tested according to ASTM standard procedure. The specific gravity test, water absorption test and fineness modulus of fine and coarse aggregates are also carried out. The compressive strength of concrete is tested without and with replacement of cement materials. The dosages of fly ash are 10 , 20 and 30 respectively and Blast furnace slag powder, 10 , 20 , 30 and 40 proportions are used for cement replacement. Different proportions of granite quarry dust 5 , 10 , 15 , 20 and 25 are also considered in this research. The compressive strengths of concrete are tested with cement and with cement replacement materials. The samples are tested for 7, 28, 60 and 91 days compressive strength.
