混合材料对高铝水泥性能的影响

INFLUINCE OF ADDITION PROPERTIES OF HIGHALUMINA CEMENT

本文研究了粒化高炉矿渣和砂岩粉对高铝水泥性能的影响。结果表明高铝水泥中掺入一定量粒化高铝矿渣能有效抑制高铝水泥六方水化物向立方水化物的转化及由此引起的强度倒缩;砂岩粉则没有发现这种抑制作用。与对比样相比,高铝水泥中掺入粒化高炉矿渣高达40～50％,对某些耐火性能影响不大。

The artiie studies the influence of granulated blast furnace slag (GBFS) and sandstone powder (SSP)on properties of high alumina cement (HAC). Results of the study show that a proper amount of GBFS mixed in HAC Will effciently prevent the conversion of the hexagonal hydratea of HAC to the cubic hydrate and the reduction of strength resulting form this conversion. This effect, however,is not found in SSP . As compared with the control sample,HAC mixed with GBFS up to 40 ?50% has little influence on some refractory properties of it.
