Light solid waste unfired ceramsite and preparation method thereof
The invention provides a light solid waste unfired ceramsite and a preparation method thereof, and relates to the technical field of building materials. The light solid waste unfired ceramsite provided by the invention comprises the following components in percentage by mass: 50-55% of steel slag powder, 10-15% of ore slag powder, 5-10% of Portland cement, 1-5% of an excitant, 3-8% of a density regulator and 20-30% of water. The density regulator comprises hollow glass beads, the true density of the hollow glass beads is 0.30-0.40 g/cm<3>, the particle size is 2-130 [mu]m, and the compressivestrength is greater than 4000 psi. The unfired ceramsite provided by the invention is light in weight, high in strength, low in water absorption rate, good in stability, low in cost, green and environment-friendly. The invention also provides a preparation method of the light solid waste unfired ceramsite, and the preparation method is simple and convenient to operate, low in cost and beneficial to realizing large-scale production.
本发明提供了一种轻质固废免烧陶粒及其制备方法，涉及建筑材料技术领域。本发明提供的轻质固废免烧陶粒包括以下质量百分含量的组分：钢渣粉50～55％，矿渣粉10～15％，硅酸盐水泥5～10％，激发剂1～5％，密度调节剂3～8％，水20～30％；所述密度调节剂为空心玻璃微珠，所述空心玻璃微珠的真密度为0.30～0.40g/cm，粒径为2～130μm，抗压强度大于4000psi。本发明提供的免烧陶粒轻质、高强、吸水率低，并且稳定性好，成本低、绿色环保。本发明还提供了所述轻质固废免烧陶粒的制备方法，操作简便，成本低，有利于实现规模化生产。
