Apr 01, 1999  Abstract. The effect of curing procedure on hardened silica fume concrete is reported. The silica fume contents were 10%, 15%, 20%, and 30% by weight of cement. The aggregate to cementitious material ratios (cement + silica fume) ranged from 1.0 to 3.8. Three different curing methods were used: steam, moist, and air curing.
