Low-carbon cementing material for foundation pit supporting and preparation method of low-carbon cementing material
The invention relates to the technical field of cementing materials, in particular to a low-carbon cementing material for foundation pit supporting, which is low in carbon, low in cost, free of sintering, excellent in physical and mechanical properties and capable of utilizing a large amount of solid waste and comprises the following raw materials: an industrial solid waste mixture, ardealite and saline-alkali soil, and the industrial solid waste mixture comprises the following raw materials: blast furnace slag, steel slag and red mud; the preparation method of the low-carbon cementing material comprises the following steps: preparing an industrial solid waste mixture through primary grinding, and preparing the low-carbon cementing material for foundation pit supporting. Saline-alkali soil is introduced as a low-cost industrial solid waste active activator, high-alkalinity non-hot-stewed steel slag and sintered red mud are introduced, the activity of the low-carbon cementing material is further improved, and the prepared cementing material for foundation pit supporting is extremely good in physical and mechanical properties and anti-permeability performance, rapid and simple to produce and extremely low in carbon emission and cost; the raw materials of the supporting low-carbon cementing material for the foundation pit are solid waste materials which are difficult to treat, various solid wastes can be treated in quantity, and the low-carbon cementing material is low-carbon and environment-friendly.
本发明涉及胶凝材料技术领域，尤其是一种低碳、低成本、免烧结、物理力学性能优良、大量利用固废的基坑支护用低碳胶凝材料，包括以下原料：工业固废混合料、磷石膏、盐碱土，其中，工业固废混合料包括以下原料：高炉渣、钢渣、赤泥；低碳胶凝材料的制备方法，包括以下步骤：初磨制备工业固废混合料、制备基坑支护用低碳胶凝材料。通过引入盐碱土作为低成本工业固废活性激发剂，引入高碱度非热焖法钢渣和烧结法赤泥进一步增加低碳胶凝材料活性，制备出来的基坑支护用胶凝材料物理力学性能、抗渗性能极好，生产迅速，简单，碳排放及成本极低；基坑用支护低碳胶凝材料原材料均为难以处理的固废材料，可大量处理多种固废，低碳环保。
