粉煤灰水泥改良垃圾土的强度试验研究

The experimental study on strength of improved MSW

分析了垃圾土的组成及性质,介绍了其特点。对人工垃圾土掺入不同质量比的粉煤灰水泥,制样、养护,在8个不同养护龄期对样品进行无侧限抗压试验,研究其随着龄期增长的各种情况下的强度特征。试验结果表明:垃圾土具有一定的结构,加粉煤灰水泥改良后,垃圾土的强度显著增强。

The nature and composition of the improvement of municipal solid waste （MSW） were analyzed. Different proportion the quality of the fly ash cement to the MSW were blended. The unconfined compressive tests were carried out in 8 different conservation age to study the strength characteristics with the growth of a variety of conservation age. The results show that the MSW has a certain structure, but the structural weak increase its fly ash cement improved, the improved MSW has a strength enhanced marked- ly. But the growth of age will be a certain degree of decline. We can conclude that there are many factors which affect the strength characteristics of the MSW in the environment.
