Foundation pit muck alkali-activated mortar as well as preparation method and application thereof
The invention relates to foundation pit muck alkali-activated mortar as well as a preparation method and application thereof, and the foundation pit muck alkali-activated mortar is prepared from the following raw materials in parts by mass: 100 parts of foundation pit muck; 25 to 80 parts of slag; 40 to 80 parts of water; 5-28 parts of an alkali activator; wherein the alkali activator is composed of 4-14 parts of water glass and 1-4 parts of sodium hydroxide. The preparation method comprises the following steps: adding the slag, the alkali activator and the water into the foundation pit muck in parts by mass, and uniformly stirring to obtain the foundation pit muck alkali-activated mortar. Compared with the prior art, the preparation method provided by the invention not only promotes the high-valued utilization of building solid wastes, but also reduces the demand of the building industry for natural resources and promotes the development of green economy, and the prepared foundation pit residue soil alkali-activated mortar has the characteristics of early setting, rapid reaching of strength and the like; the method can be applied to emergency repair and other practical engineering fields.
本发明涉及一种基坑渣土碱激发砂浆及其制备方法与应用，基坑渣土碱激发砂浆由以下质量份数的原料组成：基坑渣土，100份；矿渣，25～80份；水，40～80份；碱激发剂，5～28份；其中，所述碱激发剂由4～14份的水玻璃和1～4份的氢氧化钠组成。制备方法包括：按质量份，在基坑渣土中加入矿渣、碱激发剂和水，搅拌至均匀，即得到基坑渣土碱激发砂浆。与现有技术相比，本发明提供的制备方法不仅推动了建筑固废物的高值化利用，也减轻了建筑行业对自然资源的需求，促进了绿色经济的发展，制备得到的基坑渣土碱激发砂浆具有早凝与快速达到强度等特点，可应用于应急修补等实际工程领域。
