Solid waste-based thin-layer masonry mortar as well as preparation method and use method thereof
The invention relates to the technical field of masonry mortar, and particularly discloses solid-waste-based thin-layer masonry mortar as well as a preparation method and a use method thereof. The concrete contains more than 98wt% of solid waste, and cellulose ether is added into the solid waste residue powder, so that the activity of each component in later use of the water granulated slag, the steel slag and the desulfurized gypsum can be improved, the viscosity of a system is increased, and the stability is improved; active components in the solid waste residue powder interact with cement, so that the gelling performance of the solid waste-based thin-layer masonry mortar is improved; by limiting the dosage of the raw materials, the early hydration speed of the solid waste micro powder is controlled, the coagulation time of a cementing material system is adjusted, all the components have a synergistic effect and supplement each other, and the mechanical strength and stability of the solid waste-based masonry mortar are improved. The solid waste-based thin-layer masonry mortar provided by the invention is good in appearance quality, can reduce the mortar joint thickness from 20mm to 2-4mm, is excellent in use performance, greatly reduces the cost, and has good industrial prospects and social benefits.
本发明涉及砌筑砂浆技术领域，具体公开一种固废基薄层砌筑砂浆及其制备方法和使用方法。本发明含有98wt％以上的固体废物，在固废渣粉中加入纤维素醚，可提升水渣、钢渣和脱硫石膏在后期使用中各成分的活性，增加体系的黏度，提升稳定性；通过固废渣粉中活性组分与水泥的相互作用，提高了固废基薄层砌筑砂浆的胶凝性能；通过对各原料的用量限定，控制了固废微粉的早期水化速度，调节了胶凝材料体系的凝结时间，各组分协同作用，相辅相成，提高了固废基砌筑砂浆的力学强度及稳定性。本发明提供的固废基薄层砌筑砂浆，外观质量好，可将灰缝厚度从20mm降至2～4mm，使用性能优良，大大降低了成本，具有良好的工业前景和社会效益。
