摘要
分析了某建筑物雨水管结垢物的成分,测量了渗出水流量和Ca (OH)2浓度。结果显示:该建筑物雨水管内结垢物是以方解石结晶态存在的碳酸钙,由于防水失效,雨水渗入混凝土内部,将Ca (OH)2溶出,渗出水Ca (OH)2浓度较高,在雨水管管壁上形成CaCO3结垢,修复防水层是防止结垢的根本解决方法。
The paper analyzed the composition of fouling in the rainwater pipe,measured the seepage and Ca(OH)2 concentration.The results show that the composition of fouling in the rainwater pipe was calcite crystal.When rainwater penetrates into the concrete,Ca(OH)2 dissolves in water and form CaCO 3 fouling in the rainwater pipe.Repairing water proof layer is the fundamental solution to prevent scaling.
