Effect of Silica Fume on Mechanical Properties and Carbonation Resistance of Concrete
A designed experimental study has been conducted to investigate the effect of silica fume on mechanical properties and carbonation resistance of concrete,a large number of experiments have been carried out in this study.The results indicate that the addition of silica fume has improved the compression strength and elastic modulus of concrete.A considerable increase for the compression strength and elastic modulus of the concrete was observed by increasing the dosage of silica fume.Besides,the addition of silica fume can improve the carbonation resistance of the concrete composite evidently,and the carbonation resistance is becoming better and better as the silica fume content is increasing gradually.
