以高炉渣微粉和偏高岭土为主要原料,NaOH和Na2SiO3为复合激发剂,制备了碱激发矿渣胶凝材料,研究了炉渣粒度、碱添加量及养护制度对矿渣胶凝材料性能的影响.结果表明,炉渣粉磨至10 μm,在室温下养护,激发剂含量为12%时,样品的1 d抗压强度为17.66 MPa;当碱激发剂含量达到16%时,样品的1 d抗压强度为27.91 MPa;随着养护时间的延长,胶凝材料的抗压强度有提高的趋势,80 ℃养护可以提高胶凝材料的早期强度,但养护温度不宜过高.

Cementitious materials were prepared by using a large amount of blast furnace slag and a small amount of metakaolin as raw materials, as well as the mixture of NaOH and Na2SiO3 as alkali activator. Effects of average particle size of raw material, content of activator, curing time and temperature on the properties of cementitious materials were studied. When the content of the activator was 12% , the compressive strength was 17.66 MPa for the sample prepared from raw material granularity of 10 μm and cured at room temperature.However, it reached 27.91 MPa when the amount of activator increased to 16%. The results also showed that the compressive strength increased with the extending of the curing time. The curing temperature at 80 ℃ was more suitable for the improvement of the early strength than other temperatures but the temperature shouldnot be too high.
