含水层中氯烯烃胶对水泥与地下水发生相互作用的缓冲作用研究

利用矿渣硅酸盐水泥和氯烃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，主要表面阻止柱块的碱性和各种元素的释放。从而减弱了水泥８９混凝土柱决的相互作用。

BUFFERING EFFECT OF ALKENYL CHLORIDE GUM AND SEMENT MIXTURE TO THE REACTION BETWEEN CONCRETE AND GROUNDWATER

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.
