Hydration of cement in concrete exposed to atmospheres having varying relative humidity
Experiments conducted were designed to compare hydration of one normal and one slow hardening cement in pastes and mortars exposed to drying influence of atmospheres of varying relative humidity; initial water/cement ratios were 0.25, 0.45, 0.65 and 0.85 and cements were normal portland cement (100/0) and mixture of this cement and blast furnace slag in equal weight proportions (50/50); when continuously moist cured, 50/50 mixture hardens more slowly than 100/0 cement at early ages, but after about 3 mo difference in behavior between these mixtures is generally found to be negligible.
