| Abstract: | The super-fine sand was modified by recycled ceramic coarse sand,and recycled ceramic mixed sand was obtained.Then it was used in preparing recycled mortar.Using orthogonal experiment,the factors influencing the fluidity of the recycled mortar,such as the water-binder ratio,the recycled aggregate replacement ratio and the fly ash replacement ratio,were investigated.The major minor sequence among factors and the optimum design were obtained by means of range analysis and variance analysis,and the mechanism was analyzed.Ternary linear regression was carried out with the results and a consistency prediction model was given. |
