| Abstract: | Firstly,the best composition of the lime-fly ash mortar is determined by the orthogonal study,based on many indoor experiments and theoretical analysis;secondly,the rate of voids in the mixed aggregates is gained by the method of vibrating test,in which the optimal gradation of coarse aggregates is got.At last,the suited ratio of coarse aggregates to ash-fly mortar is determined by the volume method.Through the computation and experiment,the design of mix ratio of lime-fly ash stabilization macadam based on... |
