摘要
将30%质量的城市固体废物焚烧(MSWI)底灰掺入混凝土中替代水泥,通过对底灰混凝土的收缩率,抗碳化性、抗渗性、抗冻性等进行试验,并与普通混凝土进行对比,研究了底灰作为水泥替代物的可行性。研究结果表明,测试的垃圾焚烧底灰具有一定的火山灰活性,一定范围内掺加底灰的混凝土具有较小的收缩率,抗碳化性、抗渗性、抗冻性能优异,底灰的引入可以改善混凝土的耐久性。
Using 30% municipal solid waste incineration （MSWI） bottom ash to replace cement in concrete, the shrinkage, carbonation resistance, impermeability, frost resistance of the bottom a^h concrete are tested. Compared with ordinary concrete, the feasibility of the bottom ash as the cement substitute is studied. The study results show that the waste incineration bottom ash has a certain ash activity. The concrete with a certain amount of bottom ash has a smaller shrinkage rate and better performances of carbonation resistance, impermeability, frost resistance. Adding the bottom ash in the concrete can improve the durability of concrete.
