Low-alkalinity calcined clay cement-based porous vegetation concrete and preparation method thereof
The invention belongs to the technical field of porous vegetation concrete, and discloses low-alkalinity calcined clay cement-based porous vegetation concrete and a preparation method thereof. The porous vegetation concrete is prepared from the following raw materials in percentage by mass: 15 to 25 percent of low-alkalinity calcined clay cement, 5 to 10 percent of water, 0.5 to 1.5 percent of additive and 65 to 75 percent of gravel, the low-alkalinity calcined clay cement comprises the following raw materials in percentage by mass: 35-60% of calcined clay, 10-30% of limestone powder, 5-10% of gypsum, 15-30% of ordinary Portland cement and 5-10% of slaked lime. The porous vegetation concrete disclosed by the invention has relatively high mechanical property, porosity and durability, the slurry wrapping property is good, the pH value of the pore solution is low, and healthy growth of plants can be ensured.
本发明属于多孔植生混凝土技术领域，公开了一种低碱度煅烧黏土水泥基多孔植生混凝土及其制备方法。本发明多孔植生混凝土包括以下质量百分含量的原料：低碱度煅烧黏土水泥15～25％、水5～10％、外加剂0.5～1.5％、碎石65～75％；其中，低碱度煅烧黏土水泥包括以下质量百分含量的原料：煅烧黏土35～60％，石灰石粉10～30％，石膏5～10％，普通硅酸盐水泥15～30％，熟石灰5～10％。本发明多孔植生混凝土具有较高力学性能、孔隙率和耐久性，且浆体包裹性好、孔溶液的pH值低，能够保证植物的健康生长。
