Vegetation concrete cementing material and preparation method thereof
The invention discloses a plant-growing concrete cementing material and a preparation method of the plant-growing concrete cementing material, and belongs to the technical field of concrete cementing materials. Comprising the following raw materials in percentage by weight: 35%-55% of slag powder or granulated blast-furnace slag, 1%-40% of limestone, 5%-30% of a pozzolanic admixture and 15%-25% of an exciting agent, and the exciting agent comprises gypsum and sulphoaluminate cement clinker in a mass ratio of (75-85): (15-25). The cementing material prepared by using the slag powder or granulated blast-furnace slag meeting the requirements, matching with the proper exciting agent, compounding with the low-calcium high-silicon-aluminum volcanic ash mixed material, the limestone and the like and grinding, and has the characteristics of high fracture resistance, high compressive strength, low pH value of a hydration product and the like. According to the technology, the utilization efficiency of granulated slag is high, and the carbon emission of a cementing material product with the same-grade strength is extremely low. The preparation method is simple in process and low in production cost.
本发明公开了一种植生混凝土胶凝材料及其制备方法，属于混凝土胶凝材料技术领域，所述植生混凝土胶凝材料，包括按重量百分比计的以下原料混合粉磨而成：35％‑55％的矿渣粉或粒化高炉矿渣、1‑40％的石灰石、5‑30％的火山灰质混合材和15‑25％的激发剂，所述激发剂包括质量比为75‑85:15‑25的石膏和硫铝酸盐水泥熟料。本发明使用满足要求的矿渣粉或粒化高炉矿渣，配合适宜的激发剂，再复合低钙高硅铝的火山灰质混合材料以及石灰石等磨细制备的胶凝材料，具有抗折、抗压强度高、水化产物的pH值低等特点。该技术粒化矿渣利用效率高，同等级强度胶凝材料产品碳排放极低。本发明制备方法工艺简单、生产成本低。
