摘要：

This study is an investigation of the effect of simultaneous changes in the mixing and curing temperature (17 and 37 degree C) as well as the relative humidity of the curing medium (saturation, 75 and 33%) on the strength development in concrete (up to one year). The results indicate, in general, that the deficiency in the humidity of the curing medium, rather than the increase in its temperature, is the dominant factor affecting the strength development. The compressive strengths of the specimens kept in low humidity are reduced by 30 to 46% as compared to those cured in water. However, the warm specimens attain greater strength than the cool ones when all are kept in low humidity.
