对内掺硅烷乳液的防水混凝土进行耐久性试验,包括不同硅烷乳液掺量下混凝土的抗压强度试验、毛细吸水试验、渗透试验和抗冻试验。结果表明,内掺硅烷乳液的防水混凝土在毛细吸收和静水压力作用下有很好的抵抗水分侵入的能力。但是,由于硅烷颗粒的存在减缓了水泥的水化作用,使得内掺硅烷乳液的防水混凝土的抗压强度及抗冻性能较空白混凝土下降;并且随着硅烷掺入量的增加,其抗压强度降低、抗冻性能变差。
Durability test of waterproof concrete containing silane emulsion was carried out, including compressive strength test, capillary water absorption test, infiltration test and freeze-thaw test of concrete under different silane emulsion dosage. The results show that the water-repellent concrete with Silane-mixed emulsion has a good ability of resisting water intrusion under capillary absorption and hydrostatic pressure. However, the presence of silane particles slows the hydration of cement, making the compressive strength and frost resistance of waterproof concrete with silane-mixed emulsion decrease compared with that of blank concrete. With the increase of silane content, compressive strength Reduce, frost resistance deterioration.
