| Abstract: | 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 markedly.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. |
