摘要
研究了不同混合材在不同掺量条件下铁铝和硫盐复合水泥的强度发展。结果表明,掺入粉煤灰、石灰石和煤矸石混合材后,强度性能下降比硅酸盐水泥明显,原因是水泥浆体孔溶液的pH值较低,反应的热力学驱动大小。
Influence of different mineral admixtures and their dosages on the strength of blended ferrialuminate and sulphoaluminate cements was investigated.Results indicate that the addition of fly ash,lime stone and gangue results in obvious decrease of the strength of such blended cements comparing with that of blended portland cements,and this may be attributed to the lower pH value of pore solution in cement paste,and the lower thermodynamic driving force.Porosity of ettringite system may be determined with a proper drying process at 60℃ for 6 hours.
