钛渣与矿渣对水泥修补砂浆性能的影响

Effect of Mineral Admixtures on Properties of Cement Repair Mortar

研究了在相同水灰比下,单掺或双掺钛渣和矿渣掺合料对水泥修补砂浆流动性、强度的影响,并与水泥修补砂浆进行了比较.结果表明,与纯水泥修补砂浆相比,钛渣、矿渣等量取代水泥能改善修补砂浆的流动性;双掺钛渣和矿渣能显著改善修补砂浆的流动性,提高修补砂浆的中后期强度与耐久性.

In this paper, the effects of the simple addition and composite addition of mineral admixtures such as titanium slag, slag on the properties of fluidity, strength of repair mortar are studied in the condition of keeping the same ratio of water to cement. And the repair mortar is compared with cement repair mortar. The results indicate that compared with cement repair mortar, the displacement of cement with titanium slag or slag can improve the fluidity of repair mortar. Composite addition of both titanium slag and slag can obviously improve the fluidity of repair mortar, and improve the medium and late-term strength and durability of the repair mortar.
