Abstract

The invention discloses a lightweight high-strength concrete material with a self-leveling characteristic and a preparation and construction method thereof. Portland cement is used as a traditional cementing material, high belite cement and anhydrite are utilized, and hydroxypropyl methyl cellulose, an expanding agent, a water reducing agent, a stabilizer and the like are optimally proportioned, so that the workability and the flowability of concrete are greatly improved; meanwhile, the stability is improved, self-flowing leveling can be achieved under the influence of the gravity of materials, the effect is dense and flat after leveling, one-time forming is achieved, the phenomena of surface bubbles, yellow sand, voids, pitted surfaces and the like are avoided, the construction difficulty is lowered, the pouring time is shortened, and the working and economic efficiency is improved; damage and noise pollution caused by vibration of the heating pipe fitting or the embedded pipe fitting are avoided.

Description

technical field [0001] The invention relates to the technical field of concrete material preparation, in particular to a lightweight high-strength concrete material with self-leveling characteristics and its preparation and construction methods. Background technique [0002] With the continuous improvement of the country and the construction industry's requirements for building construction, quality, environmental protection, thermal insulation and sound insulation, traditional building materials are also facing great opportunities and challenges, especially the traditional floor leveling concrete materials and The construction technology is especially relatively backward. Its construction technology is difficult, leveling is difficult, the material itself is low in strength, easy to hollow and crack, easy to form air bubbles on the surface, yellow sand and honeycomb pockmarks, etc. It has always been difficult to effectively solve a series of problems, and the traditional C...
