Composite Portland cement and preparation method thereof
The invention relates to the field of road Portland cement preparation, and discloses composite Portland cement and a preparation method thereof. The composite Portland cement takes Portland cement clinker, steel slag, fly ash, dihydrate gypsum, an excitant and a grinding aid as raw materials. The total weight of the raw materials of the composite Portland cement is 100 parts by weight, wherein the Portland cement clinker accounts for 65-75 parts by weight, the steel slag accounts for 5-10 parts by weight, the fly ash accounts for 12-20 parts by weight, the dihydrate gypsum accounts for 5-6 parts by weight, the excitant accounts for 1-2 parts by weight, the grinding aid accounts for 1 part by weight or less, and the weight ratio of the steel slag to the fly ash is 1: (1.5-3.5). According to the technical scheme, the compressive strength, breaking strength, wear resistance and crack resistance of the road cement can be improved.
本发明涉及道路硅酸盐水泥制备领域，公开了一种复合硅酸盐水泥及其制备方法。该复合硅酸盐水泥以硅酸盐水泥熟料、钢渣、粉煤灰、二水石膏、激发剂和助磨剂为原料，以所述复合硅酸盐水泥原料的总重量为100重量份计，所述硅酸盐水泥熟料为65‑75重量份、所述钢渣为5‑10重量份、所述粉煤灰为12‑20重量份、所述二水石膏为5‑6重量份、所述激发剂为1‑2重量份、所述助磨剂为1重量份以下，其中，所述钢渣与粉煤灰的重量比为1:1.5‑3.5。本发明所述的技术方案能够改善道路水泥的抗压强度、抗折强度、耐磨性以及抗裂性能。
