Porous material composition, porous material, and preparation method and application of porous material
The invention provides a porous material composition which comprises the following components in parts by weight: 15-60 parts of cement; 40-85 parts of fine coal gasification slag; 0-20 parts of reinforcing particles; and 0-10 parts of an auxiliary cementing material. The invention also provides a porous material prepared from the porous material composition as well as a preparation method and application of the porous material. According to the porous material composition and the porous material, the coal gasification fine slag and the cement can be comprehensively utilized, the coal gasification fine slag and the cement can achieve a synergistic effect to form a special three-level pore structure, and the specific surface area and the porosity can be remarkably increased under the condition that the compressive strength is not reduced by utilizing two mesoporous structures in the three-level pore structure; the problems of low specific surface area and single pore structure of the existing biological filter material, water treatment filter material, wetland filter material and wetland filler are solved.
提供一种多孔材料组合物，其包括以下重量份数的各组分：水泥15‑60；煤气化细渣40‑85；增强颗粒0‑20；辅助胶凝材料0‑10。还提供由多孔材料组合物制得的多孔材料及其制备方法和应用。该多孔材料组合物和多孔材料能够综合利用煤气化细渣和水泥，二者能够起到协同作用，形成特殊的三级孔结构，且能够利用其中的两种介孔结构在不降低抗压强度的条件下显著增加其比表面积和气孔率；克服了现有生物滤料、水处理滤料、湿地滤料及湿地填料比表面积低、孔结构单一的问题。
