煤矸石、粉煤灰、页岩、矿渣等硅铝质原料,由于含铝量较高,作为硅酸盐水泥的原料不太适宜。近年来,由中国建筑材料科学研究院水泥所通过微量组分的引入,改变了传统的硅酸盐水泥的矿物组成,研制了一种改性硅酸盐水泥熟料。不仅为硅铝质原料的利用开创了一条新途径,而且该熟料还具有以下特点: Coal-silica, fly ash, shale, slag and other silica-alumina raw materials are not suitable as raw materials for Portland cement due to their high aluminum content. In recent years, the introduction of trace components by the China Institute of Building Materials Science has changed the mineral composition of traditional Portland cement and developed a modified Portland cement clinker. It not only created a new approach for the use of silica-alumina raw materials, but also has the following characteristics:
