Abstract

The invention discloses low-water-absorption foamed cement. The low-water-absorption foamed cement is prepared from the following raw materials in parts by weight: 100 parts of cement, 1.8 to 2 partsof a foaming agent, 0.6 to 0.8 part of a foam stabilizer, 10 to 12 parts of a waterproof agent, 0.02 to 0.04 part of a naphthalene water reducer, 0.4 to 0.6 part of a reinforcing agent, and 45 to 50 parts of water, wherein the foaming agent is lauryl sodium sulfate and fatty alcohol polyoxyethylene ether sodium sulfate. The low-water-absorption foamed cement is good in waterproof performance, lowin water absorption rate and good in strength.

Description

technical field [0001] The invention relates to the technical field of cement, in particular to a low-water-absorbing foamed cement. Background technique [0002] Foamed cement is to fully foam the foaming agent mechanically through the foaming system of the foaming machine, and evenly mix the foam with the cement slurry, and then go through the pumping system of the foaming machine for cast-in-place construction or mold molding. A new type of lightweight thermal insulation material with a large number of closed pores formed by natural conservation. [0003] Foamed cement has a porous structure and is easy to absorb water, which will affect the service life of foamed cement and limit the application of foamed cement. Contents of the invention [0004] Based on the technical problems in the background technology, the present invention proposes a low water absorption foamed cement, which has good water resistance, low water absorption and good strength. [0005] A kind of ...
