Steel slag-doped low-carbon cementing material capable of solidifying soft soil and use method of steel slag-doped low-carbon cementing material
The invention discloses a steel slag-doped low-carbon cementing material capable of solidifying soft soil, and belongs to the technical field of concrete material preparation. The low-carbon cementing material doped with the steel slag is composed of two components and is composed of water glass and a dry material. Wherein the mass part of the water glass is 65-105 parts; the dry material is prepared from the following raw materials in parts by mass: 300 to 500 parts of slag, 17 to 32 parts of quick lime, 36 to 56 parts of sodium carbonate and 147 to 197 parts of steel slag. The density of the adopted steel slag is 2.8-3.6 g/cm < 3 >, and the specific surface area is 350-425 m < 2 >/kg. The steel slag contains free MgO and CaO, so that an obvious expansion effect is achieved, and the compactness and the curing strength of the solidified soil (soft soil, the steel slag doped low-carbon cementing material and water) can be improved.
本发明公开了一种可固化软土的掺钢渣低碳胶凝材料，属于混凝土材料制备技术领域。本发明的掺钢渣低碳胶凝材料为双组分，由水玻璃和干料组成。其中，水玻璃的质量份数为65～105份；干料由以下质量份数的原料组成：300～500份矿渣、17～32份生石灰、36～56份碳酸钠、147～197份钢渣。采用的钢渣密度为2.8～3.6g/cm3，比表面积为350～425m2/kg。钢渣中含有游离的MgO和CaO，起到明显的膨胀作用，能提高固化土(软土+掺钢渣低碳胶凝材料+水)的密实性和固化强度。
