摘　　要：通过水泥净浆试验、强度试验,探讨分析了在同水灰比和同胶凝材料的条件下,不同掺量废水对水泥净浆流动度、凝结时间和安定性及胶砂的抗折和抗压强度的影响。结果表明:随着废水掺量增大,水泥净浆的流动度相对变差,但经时损失相对变好;废水掺量增大,试样的早期抗压强度的增高,但后期强度增长慢。according to cement paste test and strength test, effects of cement paste in the same water-cement ratio and under the conditions of cementitious materials with different water dosage on properties, flowability, setting time and compressive strength.The results show that with the dosage increasing wastewater,the flowability of cement paste is relative degree of deterioration,but they have slump time losing a relatively changed for the better; the strength of mortars grows faster in the early stage, but slower growth in the late strength.
