| Abstract: | This paper uses orthogonal test method to design suspension-dense mixture of cement stabilized gravel, and analyses the shrinkage performance of gravel mixed cement. In addition, the paper analysis relations between the shrinkage factor＇s changing and factors level. It is can concluded that mixture shrinkage factor is related to water mixture, cement dosage and admixture. The impact numerical of dense suspension of cement stabilized gravel shrinkage factor is calcuated. |
