Description
Technical field
The present invention relates to concrete and its preparing technical fields, and in particular to a kind of Light-weight composite concrete plank.
Background technology
In recent years, as the driving of Building Energy Conservation Policy, energy-saving building technology and energy-saving material have rapid development.It is mixed
Concrete board material is the most commonly used construction material of construction industry, and with the development of economy with the progress of technology, people are to construction material
Requirement be also continuously improved, not only require concrete plate that there is high intensity, durable requirement, and concrete plate should also expire
Sufficient lightweight, environmentally friendly requirement.The most commonly used normal concrete plank in industry and civil buildings at present, although intensity (one
As be 20-30MPa) requirement of building structure can be substantially met, but it is heavier.However, current normal concrete plank
Fragile material is belonged to air entrained concrete plank, it is easy to be generated microcrack because of contraction, be even completely destroyed.In the market
The intensity of light concrete plate is very low (general ＜ 5MPa), cannot be satisfied the requirement of building structure, can only do non-bearing every
Wall or thermal insulation material.In addition, air entrained concrete plank is highly brittle, it is easy to be crushed in work progress transporting.Therefore, it prepares
Foamed concrete plate with high-strength light, waterproof crack resistence function is urgent needs.
Invention content
It is of the existing technology the purpose of the invention is to overcome the problems, such as, a kind of Light-weight composite concrete plank is provided,
It has the characteristics that light-weight, intensity is high, disclosure satisfy that construction industry to the requirement of concrete plate performance indicator, has good application
Foreground.
To achieve the goals above, the present invention provides a kind of Light-weight composite concrete plank, by the original of following parts by weight
Material is made：25~45 parts by weight of slag powders, 15~35 parts by weight of cement, 15~30 parts by weight of fine sand, 5~12 weight of diatomite
Part, 3~15 parts by weight of precipitated calcium carbonate, 3~12 parts by weight of aluminium polychloride, 15~48 parts by weight of lightweight aggregate, waste old grain 3
~8 parts by weight, 1~5 parts by weight of reinforcing fiber, 1~3 parts by weight of foaming agent, 0.5~1.5 parts by weight of water-reducing agent, other auxiliary agents 0
~5 parts by weight.
Through the above technical solutions, the present invention uses slag powders, cement, fine sand and composite diatomite as aggregate, improve
The interior porosity of concrete plate, significantly reduces the elasticity modulus of concrete plate, while reducing the accumulation of concrete plate
Density and mass density, have the characteristics that lighting, by being modified to waste old, can be introduced on the surface of rubber granule
Charged functional groups improve its binding force, to improve concrete plate by interacting between charge after being mixed with other raw materials
Intensity, by be added reinforcing fiber, the cracking resistance and intensity of concrete plate can be significantly improved, aluminium polychloride can
The intensity for improving concrete plate can be widely applied to building enclosed structure and horizontal weighing structure, and the raw material of the present invention
Component is mostly industrial waste, can reduce pollution of the trade waste to environment.
Specific implementation mode
The endpoint of disclosed range and any value are not limited to the accurate range or value herein, these ranges or
Value should be understood as comprising the value close to these ranges or value.For numberical range, between the endpoint value of each range, respectively
It can be combined with each other between the endpoint value of a range and individual point value, and individually between point value and obtain one or more
New numberical range, these numberical ranges should be considered as specific open herein.
The present invention provides a kind of Light-weight composite concrete plank, is made of the raw material of following parts by weight：Slag powders 25~
45 parts by weight, 15~35 parts by weight of cement, 15~30 parts by weight of fine sand, 5~12 parts by weight of diatomite, precipitated calcium carbonate 3~15
Parts by weight, 3~12 parts by weight of aluminium polychloride, 15~48 parts by weight of lightweight aggregate, 3~8 parts by weight of waste old grain, reinforcing fiber
1~5 parts by weight, 1~3 parts by weight of foaming agent, 0.5~1.5 parts by weight of water-reducing agent, 0~5 parts by weight of other auxiliary agents.
In order to further increase the intensity of the light concrete plate, under optimum condition, the Light-weight composite concrete
Plank is made of the raw material of following parts by weight：30~40 parts by weight of slag powders, 20~30 parts by weight of cement, fine sand 20~25
Parts by weight, 6~10 parts by weight of diatomite, 5~12 parts by weight of precipitated calcium carbonate, 5~10 parts by weight of aluminium polychloride, lightweight aggregate 20
~45 parts by weight, 3~6 parts by weight of waste old grain, 2~5 parts by weight of reinforcing fiber, 1~3 parts by weight of foaming agent, water-reducing agent 0.5
~1.5 parts by weight, 0~5 parts by weight of other auxiliary agents.It is furthermore preferred that the Light-weight composite concrete plank, by following parts by weight
Raw material be made：35 parts by weight of slag powders, 25 parts by weight of cement, 23 parts by weight of fine sand, 8 parts by weight of diatomite, precipitated calcium carbonate 8
