Foam concrete

Abstract

The invention relates to the field of concrete, and provides foam concrete aiming at the problem that compressive strength of the foam concrete is easily influenced by the porous structure. The foam concrete is prepared from the following components in parts by mass: 14-16 parts of water, 20-25 parts of Portland cement, 11-15 parts of limestone powder, 75-85 parts of sand, 103-106 parts of stone,0.3-0.5 parts of a foaming agent, 0.1-0.5 parts of a water reducing agent, 0.3-0.5 parts of starch, 0.5-1 part of hollow glass beads and 0.1-0.3 parts of pineapple leaf fiber. Pores among cement particles can be filled with the hollow glass microbeads, so that compactness of the foam concrete is improved, and the foam concrete is not prone to cracking under pressure. Besides, the hollow glass microbeads also have certain fluidity, contain thin gas inside, and have the functions of light weight, heat insulation and sound insulation, and thus, the foam concrete has higher compressive strength while maintaining superior performance.

Description

Technical field [0001] The invention relates to the field of concrete, and more specifically, it relates to a foam concrete. Background technique [0002] Foamed concrete uses the foaming system of the foaming machine to fully foam the foaming agent mechanically, and evenly mix the foam and cement slurry, and then pass through the pumping system of the foaming machine for in-situ construction or mold forming. A new type of lightweight insulation material with a large number of closed pores formed by curing. [0003] Although the porous structure of foamed concrete makes the foamed concrete have the advantages of light weight, heat insulation, sound insulation and fire resistance, but the porous structure of foamed concrete easily affects the compressive strength of the foamed concrete, which makes the foamed concrete easy to crack when under pressure. Therefore, there is still room for improvement. Summary of the invention [0004] In view of the shortcomings of the prior art, the...

Problems solved by technology

[0003] Although the porous structure of foam concrete makes the foam concrete have superior properties such as light weight, thermal insulation, sound insulation and fire resistance, the porous structure of the foam concrete is easy to affect the compressive strength of the foam concrete at the same time, so that the foam concrete is easy to crack when it is under pressure. Therefore, there is still room for improvement
