The aspects such as border play actively significant effect.Ardealite is to prepare phosphoric acid using Wet Processes of Phosphoric Acid sulphuric acid and rock phosphate in powder reaction
The side-product for obtaining.The trade waste resources such as extensive effectively utilizes phosphorus slag, flyash, reduce environmental pollution, give full play to
The effect of trade waste and reduce the consumption of cement to reduce the production cost of concrete, be to need what is further solved to ask
Topic.
The content of the invention
To solve the above problems, the invention provides a kind of phosphorus slag, flyash and ceramsite concrete light-weight concrete, using cement,
Phosphorus slag, flyash as composite gelled material, haydite and pottery sand as light aggregate, by adding water reducer and polypropylene fibre
Further improve the performances such as its mechanical property, water absorption and coefficient of softing, prepare insulation, sound insulation, environmental protection it is light
Matter concrete.Environmental conservation and building energy conservation be nation-building it is new society key link, phosphorus slag flyash-haydite concrete
Compared with normal concrete with from heavy and light, heat-insulated, sound insulation and heat insulation effect, under the requirement for meeting design strength, general deadweight drop
It is low by 30%～40%, with significant economical, societal benefits and environmental benefit.
For achieving the above object, the technical scheme taken of the present invention is：
A kind of phosphorus slag, flyash and ceramsite concrete light-weight concrete, per 1m3Each raw material dosage of haydite concrete is：Gelling material
Material 510kg, net duty of water 200kg, pottery sand 364kg, haydite 331kg, water reducer are the 0.8～1.2% of cement mixing content, mix
Polypropylene fibre of 1.8%～2.2% length for 15mm, in the Binder Materials, cement accounts for 40～60%, and phosphorus slag powder accounts for 20
～30%, flyash accounts for 20～40%.
Preferably, the water reducer accounts for the 1.0% of Binder Materials.
Preferably, the volume of polypropylene fibre is 2.0%.
Preferably, the cement adopts composite Portland cement, and strength grade is 42.5, and apparent density is 3100kg/m.
Preferably, the fineness of phosphorus slag powder is more than 350m2/ kg, apparent density are 2850kg/m3。
Preferably, 18～45 μm of the diameter of the polypropylene fibre, cross sectional shape are Y shape, and burning-point is 590 DEG C, density

Describe in detail.It should be appreciated that specific embodiment described herein is not used to limit this only to explain the present invention
It is bright.
Raw material used in following examples is：
Cement：Composite Portland cement, strength grade are 42.5, and apparent density is 3100kg/m3。
Phosphorus slag powder：Fineness is more than 350m2/ kg, apparent density are 2850kg/m3, less than cement 3100kgm～3, mixed
It can be the weight for reducing concrete phosphorus slag powder part to be mixed in coagulating soil and substitutes cement, but a small amount of due to containing in phosphorus slag powder
P2O5Cement setting time can be extended with F, so volume is general no more than 40%.
Flyash：Apparent density be 2420kgm～3, less than phosphorus slag powder 2850kgm～3With cement 3100kgm
~3, it is the lighting for being very beneficial for increasing concrete that flyash is mixed in concrete.Although doping quantity of fly ash is bigger, mix
The more of soil weight reduction are coagulated, but volume is excessive, also results in mechanical performance of concrete etc. and drastically declines, while also needing to ensure
Certain curing age.
