某循环水场施工完毕,混凝土池壁出现60多条裂缝,最大宽度达1.5mm。经研究决定采用甲凝材料进行修补。一、甲凝材料性能甲凝是以甲基丙烯酸甲酯为主剂,过氧化苯甲酰为引发剂,二甲基苯胺为促凝剂等五种材料通过聚合反应生成的高分子聚合物。主要性能如下:1.甲凝浆液在常温下粘度比水还小,压力灌浆可使浆液灌入肉眼可见的任何细微裂缝,并能渗透混凝土裂缝两侧3～5cm,把裂缝牢固粘结起来;2.甲凝浆液在0℃以下也能固化,灌浆操
After the construction of a circulating water field was completed, more than 60 cracks appeared in the concrete pool wall with a maximum width of 1.5 mm. After the study decided to use a condensate material for repair. First, the performance of a set of coagulation A coagulation is based on methyl methacrylate as the main agent, benzoyl peroxide as an initiator, dimethyl aniline as a coagulant and other five materials through the polymerization of high-molecular polymer. The main properties are as follows: 1. A coagulated solution has a viscosity lower than that of water at room temperature. Pressure grouting allows the slurry to be poured into any fine cracks visible to the naked eye, and penetrates the concrete cracks on both sides by 3 to 5 cm, firmly bonding the cracks together; 2. A coagulated liquid can also be cured below 0 °C, grouting operation
