Description
Technical Field
The invention relates to the technical field of building materials, in particular to light foam concrete for backfilling a sunken toilet.
Background
The water seepage of the toilet is always a chronic disease of common diseases of building quality, the existing sinking toilet is basically backfilled with ceramsite, but the ceramsite only solves the problem of light weight, does not contribute to water resistance and water resistance, and the calcination of the ceramsite also generates smoke dust which is very harmful to the environment, and the country eliminates the high-pollution materials.
The foam concrete is a novel material, which is composed of a large number of tiny unconnected air holes, has the advantages of light weight, sound insulation, water resistance and pipeline protection, and has the advantages of good waterproof effect, strong bonding force with a base surface, high construction speed and the like when being applied to the backfill of a toilet.
The foam concrete is prepared by taking cement, slag derivative and fly ash as cementing materials and adding high molecular materials such as methyl cellulose ether, polyvinyl alcohol fiber, plant protein foaming agent, suspending agent, foam stabilizer and the like, and can be directly prepared into a porous light material with the apparent density of 350-550Kg/m3 by adopting a high-speed stirring mode.
The foaming amount and the anti-settling segregation are the key and difficult points of the technology. The foaming amount is too small, the apparent density of the finished product is high, and the foaming agent is too large, so that corner collapse and low strength of the finished product are easily caused. Segregation settling is to keep the slurry separated from the cementitious material in the middle of the hardening process to ensure that the slurry concentrations at the bottom and top are completely consistent.
