Abstract
The invention discloses foam concrete which solves the problem that the tensile strength of existing foam concrete is low. The foam concrete is composed of, by weight, 60-100 parts of cement, 10-20 parts of silica fume, 70-110 parts of coal ash, 0.2-2 parts of PP fiber, 20-65 parts of water, 1-2 parts of water reducer and 0.5-3 parts of foaming agent. According to the foam concrete, all the raw materials are in cooperation so that the tensile strength of the foam concrete can be obviously improved, and therefore the requirements of various building wallboards are met.
Description
Technical field
The present invention relates to a kind of foamed concrete.
Background technology
Building energy conservation is the important energy saving policy of one, China, become the study hotspot in construction work and building material industry, but novel environment-friendly heat-preserving building energy-saving material is then a kind of important form of building energy conservation.Foamed concrete, as a kind of Novel energy saving thermal insulation material, has the features such as light weight, fire line be good, has broad application prospects in wall heat insulation material.Compared with the concrete that other are common, the advantages such as foamed concrete has compressive strength and resistance to deterioration, high temperature resistant type, good environmental protection, thermal insulation is good, construction intensity is high, rate of permeation is low, impermeability is good, but there is the low shortcoming of tensile strength in it simultaneously.
Summary of the invention
The object of the present invention is to provide a kind of foamed concrete, solve the problem that existing foamed concrete tensile strength is low.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of foamed concrete, is made up of the raw material of following weight part:
Cement 60 ~ 100 parts
SILICA FUME 10 ~ 20 parts
70 ~ 110 parts, flyash
PP fiber 0.2 ~ 2 part
20 ~ 65 parts, water
Water reducer 1 ~ 2 part
Whipping agent 0.5 ~ 3 part.
Below provide several concrete scheme:
Scheme one: described foamed concrete by weight part be the cement of 80 parts, the SILICA FUME of 15 parts, the flyash of 85 parts, the PP fiber of 1 part, the water reducer of 1.5 parts, the whipping agent of 1 part, 40 parts of water form.
Scheme two: described foamed concrete by weight part be the cement of 90 parts, the SILICA FUME of 11 parts, the flyash of 100 parts, the PP fiber of 0.75 part, the water reducer of 1.2 parts, the whipping agent of 1.2 parts, 60 parts of water form.
Scheme three: described foamed concrete by weight part be the cement of 65 parts, the SILICA FUME of 18 parts, the flyash of 107 parts, the PP fiber of 1.85 parts, the water reducer of 1.8 parts, the whipping agent of 2 parts, 55 parts of water form.
Scheme four: described foamed concrete by weight part be the cement of 85 parts, the SILICA FUME of 17 parts, the flyash of 90 parts, the PP fiber of 1.35 parts, the water reducer of 1.3 parts, the whipping agent of 1.5 parts, 30 parts of water form.
Scheme five: described foamed concrete by weight part be the cement of 95 parts, the SILICA FUME of 12 parts, the flyash of 75 parts, the PP fiber of 1.5 parts, the water reducer of 1.7 parts, the whipping agent of 2.2 parts, 45 parts of water form.
What deserves to be explained is, the preparation method of foamed concrete of the present invention is identical with existing preparation method, therefore is not repeating at this.
The present invention compared with prior art, has the following advantages and beneficial effect:
The present invention adopts the cooperation each other of each raw material, ultimate compression strength of the present invention is significantly improved, thus meets the requirement of various building wall board.
Embodiment
Below in conjunction with embodiment, the invention will be further described, and embodiments of the present invention include but not limited to the following example.
Embodiment 1
