摘要:
混凝土吸水性是混凝土耐久性能评价的重要指标.采用混凝土下部吸水的方法,试验研究了混凝土水灰比、烘干温度、水浸没试块的深度以及试验环境的温度和相对湿度对混凝土吸水性的影响规律.试验结果表明:水灰比和烘干温度对混凝土吸水性影响显著;水浸没深度控制在5mm以内对混凝土吸水性影响不大.吸水试验的环境温度和相对湿度增加,会促进水的毛细吸收,毛细吸收对环境温度的敏感性要高于环境相对湿度
Abstract:
Concrete sorption capacity is an important index of durability appraisal. The theory and measurement of capillary suction in the concrete were introduced. The effect of water-cement ratio, drying temperature, submerged depth, environmental temperature and relative humidity on sorption capacity in the concrete were investigated by the capillary rise test. The test results showed that water-cement ratio and drying temperature had significant effects on concrete sorption capacity. The submerged depth below 5mm had little effect on it. The increase of the environment temperature and relative humidity could promote the concrete sorption capacity. The sensitivity of the environmental temperature on the sorption capacity was higher than that of the relative humidity
