The Effect of Mineral Admixtures on Behavior of Reinforced Concrete against Attack Chloride Salt
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2019, Vol 16, Issue 1
Abstract
The effect of mineral admixtures on behavior of reinforced Concrete against attack chloride salt was investigated experimentally. The program of the study consisted of casting, curing and testing of three mixes. Mix one contains ordinary Portland cement. Mix two contains ordinary Portland cement and 10% fly ash. Mix three contains ordinary Portland cement and 10% silica fume. For every mix cubes (100*100*100 mm) and cylinders (100*200 mm) without and with 16 mm steel reinforcement were molded. Samples were exposed to sodium chloride solutions (NaCl) with concentration of 0%, 5%, 7%, and 9% until time periods 28, 60 and 90 days. The mechanical properties concrete compressive strength, splitting tensile and rate of steel corrosion were measured. The results show that the values of compressive and splitting tensile strengths increase when the chloride ratio 5% more than 0%. Moreover the values of compressive and splitting tensile strengths decrease when the chloride ratio 7% and 9% respectively. Increasing the chloride ratio increase the corrosion rate. The compressive and splitting tensile strengths of silica fume show the highest result as compared to the fly ash and ordinary Portland cement. The corrosion rate of silica fume shows the lowest result as compared with the fly ash and ordinary Portland cement.
