摘　　要：通过Cl-电通量试验和碳化试验,探讨分析了同水灰比、不同外掺料两种的情况下,掺入不同比例的搅拌站废水对C80混凝土耐久性的影响。通过SEM微观检测表明,随着废水掺量增大,混凝土的密实度随之略有提高。电通量试验和碳化试验证明废水掺量对混凝土的抗Cl-渗透和碳化性能影响较小。accorded to electric flux and carbonation tests,effects of C80 concrete mixture in the same water -cement ratio with two dif- ferent admixture and under the conditions of materials with waster water dosage on properties and durability.The results show that with water content in concrete C1 - and carbonation was less affected,Using SEM microscopic detection methods see,with wastewater dosage increasing, the density of concrete along with some improvement.
