渗透结晶型涂料对砂浆性能的影响及其机理研究

Research of the Effect of Permeable Crystalline Material on the Performance of Mortar and Its Mechanism

研究了渗透结晶型防水涂料对水泥砂浆试件的力学性能、抗渗性能以及微观结构的影响,并探讨了渗透结晶型防水涂料的反应机理,结果表明渗透结晶型防水涂料的涂层确实可以通过活性离子传输引发渗透结晶反应,达到堵塞水泥砂浆内部孔隙,增强水泥混凝土性能的目的.

The impermeability and compressive strength different coverage rates and curing time were investigated. of samples treated by permeable crystalline coating for In the meantime, the effect of permeable crystalline coating on the microstructure of mortar was studied by SEM. It is indicated that the permeable crystalline coating of not only can repair the pores and crack of mortar during its curing process, but also the permeable pathway caused by impermeability test can be healed. Therefore, the permeable crystalline coating can enhance the performance of concrete by the ionic transmission.
