Abstract

The invention provides self-compacting leveling concrete and a preparation method and usage thereof, and relates to the technical field of building materials. The self-compacting leveling concrete isprepared from 250-510kg / m<3> of fast setting fast hardening high belite sulphoaluminate cement, 687-1070kg / m<3> of a fine aggregate,815-1042kg / m<3> of a coarse aggregate, 120-182kg / m<3> of water and 0.8-9.2k / m<3> of a water reducing agent. The cement-based self-compacting leveling concrete prepared by using the fastsetting fasthardening high belite sulphoaluminate cement has the outstanding advantages of small shrinkage, high bonding strength, fast setting, fast hardening and the like, which makes it possible to prepare large-area continuous ground leveling, the construction speed can be greatly improved, the tool turnover efficiency can be improved, and the construction period can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a self-compacting leveling concrete and its preparation method and application. Background technique [0002] The usual construction process of the traditional ground is to make base concrete, then process the base concrete (including cleaning, brushing grout, punching bars, etc.), and finally level it with cement mortar. At present, low-temperature quick-drying moisture-proof leveling mortar, fast (2-4 hours can be used) leveling mortar, polymer (cellulose) modified leveling mortar, lightweight leveling mortar, leveling mortar for permeable brick paving, lightweight High-quality dry powder leveling mortar, early-strength gypsum-based thick-layer leveling mortar and early-strength cement-based thick-layer leveling mortar; and, in recent years, in order to simplify the construction process, reduce construction difficulty, and speed up the construction period, in industr...
