摘要
采用雾室养护和自然养护两种方式,研究了苯乙烯-丁二烯乳液(SB-latex)与硅灰(silicon fume)共掺时,其掺量对混凝土抗水渗透、抗氯离子渗透、抗碳化和抗硫酸腐蚀性能的影响。试验结果表明苯乙烯-丁二烯乳液和硅灰的共掺可显著地改善混凝土的渗透性,不过SB-latex和硅灰掺量较大时,会分别对混凝土的抗硫酸腐蚀和抗碳化性能产生一定的不利影响。
The influences of contents of added SB-latex and silicon fume on the properties of water-permeation, chloride diffusion, carbonation and sulphate atacking resistance to concrete are tested. Frog curing and natural curing were adopted in this study. The experimental results show that addition of SB-latex and silicon fume can obviously improve the concrete permeability. But over dosage of SB-latex and silicon fume will be harmful respectively to carbonation and sulphate atacking resistances of concrete.
