Abstract
Environment-friendly high-strength wear-resistant self-leveling mortar belongs to the field of building materials. The mortar is prepared from cement, a mineral admixture, pyrite tailings, natural sand, an additive and water; the mass ratio of the cement to the mineral admixture is (0.5-1) to (0-0.5); the mass ratio of the natural sand to pyrite tailings is 1 to (0.9-1.6). In the invention, the cement is used as a cementitious material; a secondary pozzolanic reaction is performed by using a cement hydrated product, high-activity mineral slags and pyrite tailing fine powder to produce more cementitious substances, thereby enhancing the early strength of the self-leveling mortar. The self-leveling mortar has an excellent vibration-free performance, and the surface after construction is flat and smooth and the mortar can be used as disposable clear water decorative floor, and is fast in strength development, low in shrinkage and high in wear resistance.
Description
technical field [0001] The invention belongs to building materials, in particular to a cement-based self-leveling mortar. Background technique [0002] Self-leveling mortar is a dry-mixed powdery material composed of a variety of active ingredients. It can be used after mixing with water on site. After a little spreading with a scraper, a high-level base surface can be obtained. The hardening speed is fast, and it can be walked on in 24 hours. Or carry out follow-up finishing layer engineering (such as laying wood boards, gold steel plates, etc.), the construction is quick and easy. The main material of self-leveling mortar is composed of cementitious material, fine aggregate, redispersible latex powder, water reducer, shrinkage reducer, water retaining agent, water, etc. in a certain proportion. In recent years, due to the massive mining of machine-made sand and river sand, it has caused serious harm to resources and the environment. At the same time, some cement-based sel...
