High-density and high-strength calcium magnesium silicate board and preparation method thereof
The invention belongs to the field of calcium silicate board wall materials, and discloses a high-density and high-strength calcium magnesium silicate board and a preparation method thereof. The high-strength and high-density calcium magnesium silicate board comprises the following components in percentage by mass: 15%-25% of cement, 20%-35% of slaked lime powder, 40%-60% of graded quartz sand and 0.5-3% of magnesium oxide powder. The graded quartz sand is composed of quartz sand with three particle size intervals. The prepared calcium silicate board is low in porosity, high in density and high in breaking strength, meanwhile, the application limitation of magnesium-containing carbonate and magnesium-rich resources in the field of calcium silicate boards is solved, and discarding and idling of the magnesium-containing carbonate and the magnesium-rich resources, resource waste and environment pollution are avoided.
本发明属于硅酸钙板墙体材料领域，公开了一种高密度高强度硅酸钙镁质板材及其制备方法。所述高强高密度硅酸钙镁质板材包括下述质量百分比的组分：水泥15％‑25％，消石灰粉20％‑35％，级配石英砂40％‑60％，氧化镁粉0.5‑3％。其中级配石英砂由三个粒度区间的石英砂组成。本发明制得的硅酸钙板孔隙率低、密度高、抗折强度高，同时解决了含镁碳酸盐和富镁资源在硅酸钙板领域的应用限制，避免其抛弃、闲置，浪费资源并污染环境。
