Abstract

Two types of flyash and two types of additives were investigated at the environmental temperature 10deg C, 20deg C, and 30deg C. In the environmental temperature10deg C, the strength enhancement effect was seen rather than ordinary portland cement mix proportion in 1day. In environmental temperature 20deg C, although there was strength development rather than the additive-free of flyash mix proportion, strength development was not seen rather than ordinary portland cement mix proportion. In the environmental temperature 30deg C, the trend for strength to decline rather than the additive-free of flyash mix proportion according to the kind of an additive and flyash.
