Abstract:The effect of different environmental conditions on the rate and amount of water evaporation from fresh mortar and concrete surfaces was investigated. The variables studied were air temperature, initial mortar and concrete temperature, wind speed, relative humidity, type of cement, and water content (water-cement ratio). The results show that in hot, humid climate evaporation is 3 1/2 times lower than in a hot, moderate climate and 7% times lower than in a hot, dry climate. There is an indication that Menzel’s formula may not be applicable for estimating evaporation rate at any stage of fresh mortar or concrete in any climatic conditions.
