Cementing material for low-alkali and fertilizer-efficiency slow-release vegetation concrete and preparation method of cementing material
The invention discloses a cementing material for low-alkali fertilizer-efficiency slow-release vegetation concrete and a preparation method of the cementing material. The cementing material is prepared from 40-65 parts of slag sulphoaluminate cement, 3-30 parts of high-belite sulphoaluminate cement clinker, 5-10 parts of modified sepiolite, 2-5 parts of phosphorus-containing waste, 1-5 parts of clay minerals and 2-12 parts of electrolytic manganese residues. The cementing material disclosed by the invention is applied to base vegetation concrete and has the characteristics of low alkalinity pH value, low hydration heat and high early-stage and later-stage strength; more effective internal curing materials can be provided, and the early-stage crack resistance of the concrete is improved; the pH value of the cementing material is reasonably and effectively adjusted by adopting the solid waste material, the pH value range is wide, germination and rooting of plant seeds are facilitated, effective fertilizer is loaded, and the fertilizer efficiency is slowly released; storage and release of water, fertilizer ions or molecules are controlled, and water storage in rainy seasons and release in dry seasons of the base vegetation concrete, load storage of the fertilizer ions or molecules in the topdressing period and slow release in the later period are achieved.
本发明公开了一种低碱、肥效缓释植被混凝土用胶凝材料及其制备方法，所述胶凝材料包括40‑65份矿渣硫铝酸盐水泥、3‑30份高贝利特硫铝水泥熟料、5‑10份改性海泡石、2‑5份含磷废弃物、1‑5份黏土矿物和2‑12份电解锰渣。本发明的胶凝材料应用于基层植被混凝土，具有碱度pH值低，水化热低，早期、后期强度高的特点；能提供更有效的内养护材料，提高混凝土的早期抗裂性能；采用固废材料合理有效调节胶凝材料pH值，具有较广的pH值范围利于植物种子萌发生根，负载有效肥料，并缓慢释放肥效；控制水分、肥料离子或分子的存储及释放，实现基层植被混凝土雨季储水旱季释放，追肥期肥料离子或分子的负载存贮及后期缓慢释放。
