摘要:
利用矿渣硅酸盐水泥和氯烯烃胶研究了在营造的地下水环境和含水层环境中,氯烯烃胶对水泥混凝土与地下水之间发生相互作用的缓冲作用.研究结果表明,在营造的地下水和含水层环境中,氯烯烃胶对水泥混凝土与地下水之间的相互作用有一定的缓冲作用,主要表现在阻止柱块的碱性和各种元素的释放,从而减弱了水泥混凝土柱块与地下水的相互作用这种缓冲作用主要是由于氯烯烃胶和水泥混凝土柱块与水泥混凝土柱块的表面结构的不同所致.进一步的分析表明,这种缓冲作用有可能延长水泥混凝土在含水层中的寿命.

Abstract:
The buffering effect of a mixture of alkenyl chloride gum and cement to the reaction between concrete and groundwater in artificially constructed groundwater environment and aquifer environment was investigated with the alkenyl chloride gum and slag sillicate cement.By emerging concrete column and concrete column coated with the mixture in the artificially constructed groundwater environment and aquifer environment, and sampling water samples in the environments periodically and analysing the concentration of elements K, Na, Ca, Mg, etc. and pH as a function of emerging time, the concentration of elements K, Na, Ca, Mg, etc. and pH in the environments as a function of emerging time and the inducing reason were analysed quantitatively. The investigation indicates that in the artificially constructed groundwater environment and aquiter enrironment, the mixture can buffer the reaction between concrete and groundwater. The buffering effect mainly comes to the buffering of the release of the alkalinity of the concrete, and thus weakening the reaction between concrete and groundwater. JSM analysis indicates that the buffering effect is probably induced by the difference in surface structure from the concrete column to the concrete column coated with the mixture. Further analysis indicates that this buffering effect could increase the life time of concrete in aquifer.
