高寒地区混凝土防渗节水问题的探讨

渠道混凝土防渗节水工程是提高农田灌溉面积，减少水资源浪费的有效措施之一，文章提出了混凝土防渗节水设计的具体内容，包括混凝土水灰比的设计，不同砂粒的最佳搭配，骨料的最佳选择及最佳灰砂比的确定，以及根据裂缝，温度，湿度对混凝土的影响所应采取的相应防治措施。

Probe into Seepage Controlling and Water Saving of Concrete in Paramos

Construction of channel concrete seepage controlling and water saving works is an effect measure for increasing the irrigated area of the farmland and reducing the dissipation of water resources. This paper puts forward the concrete contents of concrete seepage controlling and water saving design, including the design of water-cement ratio of concrete, the optimized proportion of different sand grains, the optimized selection of aggregates, the determination of optimized cement-sand ratio, and some corresponding preventive measures should be taken according to the influence of the crack, temperature and moisture on the concrete.
