42.5-grade ordinary low-alkali Portland cement containing sandstone and preparation method thereof
The invention discloses 42.5-grade ordinary low-alkali Portland cement containing sandstone and a preparation method thereof. The cement comprises a component A and a component B, wherein the component A comprises Portland cement clinker, furnace slag, fluorgypsum and glass fiber; the component B comprises sandstone, furnace slag, fluorgypsum and high-calcium limestone; wherein the Portland cementclinker comprises the following raw materials in percentage by mass: 70-80% of raw material limestone, 15-20% of raw material sandstone and 5-10% of raw material slag; wherein the mass ratio of the component A to the component B is (75-85): (15-25); wherein the mass ratio of the component A to the component B is (60-80): (20-40); by adopting the application of the sandstone cloud magnesium slag in the production of the ordinary low-alkali Portland cement, the production cost of the ordinary low-alkali Portland cement is effectively reduced, meanwhile, the content of free calcium oxide and alkali in the cement is reduced, the cement performance is optimized, and the cement construction performance is improved.
本发明公开了一种含有砂岩的四十二点五普通低碱硅酸盐水泥及其制备方法，包括A组分与B组分；所述A组分包括：硅酸盐水泥熟料、炉渣、氟石膏、玻璃纤维；所述B组分包括：砂岩、炉渣、氟石膏、高钙石灰石；其中所述硅酸盐水泥熟料的原料质量百分比为：原料石灰石70%～80%、原料砂岩15%～20%、原料炉渣5%～10%；所述A组分与B组分的质量比为（75～85）：（15～25）；所述A组分与B组分的质量比为（60～80）：（20～40）；本发明通过采用砂岩云贷镁渣在普通低碱硅酸盐水泥生产中的应用，有效缩减了普通低碱硅酸盐水泥的生产成本，同时降低了水泥游离氧化钙及碱含量，优化水泥性能，提高水泥施工性能。
