混合材对水泥与聚羧酸减水剂相容性的影响

摘要

The two kinds of blending materials (i.e. fly ash and ground water-granulated blast furnace slag ) on the actions of poly-carboxyl-ate superplastieizer to cement are investigated by testing the fluidity and fluidity loss of cement pastes added with poly-carboxylste superpiaslicizer. The results show that ground water-granulated blast furnace slag in cement could enhance the compatibility between surperplaster and cement while addition of fly ash could lead to reduction and fast loss of fluidity of cement pastes.%通过对聚羧酸高效减水剂水泥净浆流动度及流动度损失的测定试验,研究了粉煤灰和水淬高炉矿渣在不同替代率及不同配比情况下对减水剂效果的影响.研究结果表明:水淬高炉矿渣有利于改善水泥与减水剂的相容性,而掺粉煤灰则会导致减水剂塑化作用的降低,而且浆体流动度损失也有增大趋势.
