Two concrete mixes with 20% silica fume and water/cementitious ratios of 0.3 and 0.46 were compared with corresponding OPC concrete mixes. The effect of both cold and dry curing on the major engineering properties and the progress of the pozzolanic reaction was measured at ages up to 90 days. The long term effect was evaluated with further measurements after a year. The paper shows that silica fume (SF) which is a highly reactive pozzolanic material is very sensitive to low temperature curing and drying out during curing. This effect should be taken into account when designing silica fume concrete for durability and performance.
