Alkali-free vegetation concrete
The invention relates to alkali-free vegetation concrete which comprises the following components: a special cementing material for the unfired alkali-free vegetation concrete, unfired sludge ceramsite, a water reducing agent, tap water and liquid CO2, and the special cementing material for the unfired alkali-free vegetation concrete comprises the following components: S95 mineral powder, steel slag powder, desulfurized gypsum powder, polyferric sulfate and potassium alum. The unfired sludge ceramsite comprises the following components: a special cementing material for unfired alkali-free vegetation concrete and river and lake sludge. According to the alkali-free plant-growing concrete, a large amount of steel slag, desulfurized gypsum and river and lake sludge can be utilized, and the alkali-free plant-growing concrete is free of sintering, low in cost, extremely low in carbon emission and ultralow in alkali content; liquid CO2 is used for rapid carbonation, long-time carbonization curing and large-scale investment on carbonization curing equipment are not needed, and the physical and mechanical properties and durability of the prepared product are better than those of common vegetation concrete, and the product is alkali-free; the common problem of high alkali content of hydrated common vegetation concrete can be effectively solved, and plant growth is promoted.
本发明涉及一种无碱植生混凝土，包括以下组分：免烧无碱植生混凝土专用胶凝材料、免烧淤泥陶粒、减水剂、自来水、液态CO2，免烧无碱植生混凝土专用胶凝材料包括以下组分：S95矿粉、钢渣粉、脱硫石膏粉、聚合硫酸铁、钾明矾，免烧淤泥陶粒包括以下组分：免烧无碱植生混凝土专用胶凝材料、河湖淤泥。本发明的无碱植生混凝土，可大量利用钢渣、脱硫石膏及河湖淤泥，免烧结，成本低，碳排放量极低，含碱量超低；用液态CO2进行快速碳酸化，无需长时间碳化养护及大规模投资碳化养护设备，所制备的产品物理力学性能及耐久性由于普通植生混凝土，且无碱；可有效解决普通植生混凝土水化后的含碱高通病，促进植物生长。
