Cement-based porous high-strength baking-free lightweight aggregate and preparation method thereof
The invention is suitable for the technical field of building materials, and provides a cement-based porous high-strength baking-free lightweight aggregate and a preparation method thereof. The cement-based porous high-strength baking-free lightweight aggregate is prepared from, by mass, 35-55% of fly ash, 23-45% of cement, 8-33% of perlite powder, 3-7% of calcium oxide and 0.8-2.5% of early strength agent; in the production process, pollution to the environment is reduced, industrial waste generated currently is fully utilized for production, and resources and energy are saved; and lightweight aggregate with multiple density grades and multiple strengths is produced, and the requirements of lightweight aggregate concrete with multiple density grades and strength grades are met.
本发明适用建筑材料技术领域，提供一种水泥基多孔状高强免烧轻骨料及其制备方法，所述水泥基多孔状高强免烧轻骨料，按质量百分数计，包括以下组分：粉煤灰35～55％、水泥23～45％、珍珠岩粉未8～33％、氧化钙3～7％、早强剂0.8～2.5％；本发明生产过程中减少了对环境的污染，充分利用现己产生的工业废料生产，节约资源、能源；实现生产多密度等级，多种强度的轻骨料，满足多种密度等级、强度等级轻骨料混凝土的需求。
