Wear-resistant floor concrete and preparation method thereof
The invention discloses wear-resistant floor concrete and a preparation method thereof. The wear-resistant floor concrete comprises 250-300 kg/m < 3 > of cement, 50-100 kg/m < 3 > of lithium slag powder, 1-3 kg/m < 3 > of magnesium fluosilicate, 0.5-2 kg/m < 3 > of aluminum dihydrogen phosphate, 0.5-5 kg/m < 3 > of hydroxyapatite, 0.5-1 kg/m < 3 > of nano calcium sulfate, 1200-1400 kg/m < 3 > of gravel, 700-900 kg/m < 3 > of machine-made sand, 5-10 kg/m < 3 > of a water reducing agent and 140-170 kg/m < 3 > of water. On one hand, the shape of machine-made sand particles is improved, and the matching effect among aggregates is fully utilized, so that a framework compact structure is formed; on the other hand, by introducing the lithium slag powder, magnesium fluosilicate, aluminum dihydrogen phosphate, hydroxyapatite and nano calcium sulfate, the compactness, wear resistance and cracking resistance of the concrete are improved, and meanwhile shrinkage can be effectively reduced; the obtained product is good in workability, high in water retention capacity, high in surface wear resistance and relatively high in crack resistance.
本发明公开了一种耐磨地坪混凝土及其制备方法，组成为水泥250～300kg/m3，锂渣粉50～100kg/m3，氟硅酸镁1～3kg/m3，磷酸二氢铝0.5～2kg/m3，羟基磷灰石0.5～5kg/m3，纳米硫酸钙0.5～1kg/m3，碎石1200～1400kg/m3，机制砂700～900kg/m3，减水剂5～10kg/m3，水140～170kg/m3；一方面通过改善机制砂颗粒粒形，充分利用骨料间的搭配作用，形成骨架密实性结构；另一方面，通过引入锂渣粉、氟硅酸镁、磷酸二氢铝、羟基磷灰石、纳米硫酸钙提高混凝土的密实度、耐磨性和抗开裂能力，同时能够有效降低收缩；所得产品工作性好，保水能力强，表面耐磨性强，具有较强的抗裂能力。
