一、概述用普通的水泥砂浆(R压=600kg/cm~2)为基材,MMA为其浸渍剂,在200大气压的高压下浸渍并聚合,制得R压为2400kg/cm~2的PIC(聚合物浸渍混凝土)。而使用同样的材料,通过常规浸渍后制得的PIC,其抗压强度为1600kg/cm~2。它们的聚合物浸填量分别为9.2％和7.5％。超高强PIC获得的主要因素我们认为有如下几点:①残留空气的影响大幅度下
I. Overview A common cement mortar (R pressure = 600kg/cm~2) is used as the substrate, MMA is its impregnant, and it is impregnated and polymerized under high pressure of 200 atmospheres to obtain a PIC with R pressure of 2400kg/cm~2. (Polymer impregnated concrete). Using the same material, the PIC obtained after the conventional impregnation had a compressive strength of 1,600 kg/cm 2 . Their polymer immersions were 9.2% and 7.5%, respectively. The main factors for the acquisition of ultra-high-strength PICs are as follows: 1 The impact of residual air is greatly reduced.
