不同融雪剂对水泥混凝土耐磨性影响试验

Effect of different snowmelt agent on the wear resistance of cement concrete

用不同质量分数的氯化钠、氯化镁、氯化钙、硝酸镁及自制CMA融雪剂溶液,对水泥混凝土试件进行了冻融试验,测试不同质量分数、不同种类融雪剂对水泥混凝土磨耗损失的影响。结果表明:当氯化钠和氯化钙溶液的质量分数为2%和4%时,混凝土的磨耗损失达到100%,当CMA溶液质量分数为4%和20%时,混凝土的磨耗损失分别为21.99%和3.56%;CMA与其他融雪剂相比,对混凝土腐蚀影响最小,是一种低腐蚀性的环保型融雪剂。

Under the condition of freeze-thawing test for cement concrete test block, the effects of different mass fraction of snowmelt agent solution and different kinds of Snowmelt agent, such as Sodium chloride, magnesium chloride, calcium chloride, CMA and so on, are studied by abrasion loss. The results show that when the mass fraction of sodium chloride and calcium chloride is 2% and 4%, the abrasion loss of concrete can reach 100%. When the mass fraction of CMA is 4% or 20%, the abrasion loss of concrete is 21.99% or 3.56% respectively. Compared to other snowmelt agent, CMA is a kind of environment friendly snowmelt agent which has the advantage of low corrosion.
