Abstract
The invention discloses a kind of building waste pervious concrete preparation methods, selection building waste partial size is 5~10mm, natural stone is substituted using building waste, form concrete skeleton, coal ash instead part of cement, addition additive improves concrete performance and proposes the calculation method of exact each component material utilization amount using relationship between quality between each component and the inherent parameters of each material.This method chooses the single building waste of partial size, can debug concrete performance by control aggregate size.This method has larger effect to the improvement of concrete performance using flyash part substitution cement and addition additive.Pervious concrete is prepared using building waste, realizes the recycling of solid waste, is conducive to environmental protection, reduces engineering cost.
Description
Technical field
The invention belongs to waste and scrap recycle utilization technology fields, more particularly to raw using the pervious concrete of building waste
Produce preparation method.
Technical background
With the development of Development of China's Urbanization, building waste yield is increasing year by year, it was reported that and standing crop has surpassed 20,000,000,000 tons,
But utilization rate is less than 5%, far below developed countries such as America and Europes.It is domestic at present more random to the processing of building waste, mostly only
It is simply filled or is toppled over, occupy a large amount of lands used, destroy soil texture, cause ground settlement, pollute environment.As economical fast
Speed development, the resource usage of infrastructure is growing day by day, and transition exploits natural sand stone and destroys the ecological balance, brings to human lives
Many influences, country have begun the exploitation of limitation sandstone, put into effect relevant policies and encourage Green Development, reinforce to the sharp again of solid waste
With, be realize sustainable development the only way which must be passed." blue montains and green waters is exactly Kingsoft Yin Shan ", " blue montains and green waters is rather wanted, it should not Kingsoft silver
Our attention to environment of the present age are embodied on mountain ", we will also take into account the protection to natural environment in economic construction simultaneously, and solid waste is again
Utilize a kind of important means for being environmental protection.
Pervious concrete is made of raw material such as coarse aggregate, cementitious material, additive and water, is wrapped up in by coarse aggregate surface
Attached a thin layer cement slurry is mutually bonded into the equally distributed honeycomb structure in hole, has the features such as ventilative, permeable and light.Make
For a kind of celluar concrete, pervious concrete is commonly applied to pavement, garden landscape road, society's internal road and service area etc..
Pervious concrete can reduce waterlogging, sqouynd absorption lowering noise, reduce urban heat land effect compared with normal concrete, raw to local soil
State environment plays a role in improving.It is coarse aggregate as the main composition material of pervious concrete, the shortage of sandstone material is also serious
The material cost valence for influencing pervious concrete, limits its popularization and application.So finding thick bone in a kind of alternative pervious concrete
The material of material has become hot research direction.
Summary of the invention
It overflows for building waste and the problems such as sandstone is in short supply, the present invention provides a kind of permeable with solid waste material substitution
The method of natural coarse aggregate in concrete, and according to the characteristic of building waste, reach Performance optimization by adjusting match ratio,
It prepares a kind of with pervious concrete of good performance, the recycling of realization solid waste material.
The technical problems to be solved by the invention are realized using following technical scheme:
A kind of building waste pervious concrete preparation method, includes the following steps:
(1) building waste pervious concrete includes coarse aggregate building waste, cementitious material, water and additive.
(2) coarse aggregate building waste forms skeleton in building waste pervious concrete, and cementitious material wraps up the table of coarse aggregate
Cementation is played in face, and additive is to improve concrete performance.
(3) building waste pervious concrete, coarse aggregate account for 60~75%, and additive accounts for 1~2%, and water accounts for 5~10%, coagulate
Glue material accounts for 20~30%, and synthesis ratio is 100%.
Coarse aggregate size is the building waste of 5~10mm.
Cementitious material includes cement and flyash, and cement consumption is 75~90% in cementitious material, flyash 10~25%,
Synthesis ratio is 100%.
Each component volume is calculated according to following formula in building waste pervious concrete:
mg=0.98 ρg
In formula:
mgFor coarse aggregate building waste quality (kg)；ρgFor coarse aggregate bulk density (kg/m3)；
mcFor cement quality (kg)；mzFor flyash quality (kg)；
mwFor the quality (kg) of water；mkFor additive quality (kg)；
rgFor the apparent density (kg/m of coarse aggregate3)；rcFor the apparent density (kg/m of cement3)；
rwFor the apparent density (kg/m of water3)；rzFor the apparent density (kg/m of flyash3)；
α is coal ash instead cement consumption mass fraction (%)；β is that admixture dosage accounts for cementitious material mass fraction
(%)；
W/B is water-cement ratio.
Additive is naphthalene water reducer, and volume is 1.0~2.0%.
The method have the benefit that:
(1) a kind of building waste pervious concrete preparation method of the present invention, choose building waste partial size be 5~
10mm promotes the performance of building waste pervious concrete, and can be according to certainly by controlling the partial size mixture proportion of building waste
Body performance requirement realizes that pervious concrete performance is controllable by deploying each material mixture proportion.
(2) a kind of building waste pervious concrete preparation method of the present invention substitutes natural stone using building waste,
Coal ash instead part of cement, realizes the utilization again of solid waste material, and protection environment reduces engineering cost.
(3) a kind of building waste pervious concrete preparation method of the present invention, from performance perspective, mineral powder material
Material uses flyash, establishes its relationship between voidage and intensity, establishes the permeable coagulation of building waste using mass parameter
Each component calculated relationship in soil, and then improve pervious concrete performance, convenience is provided for pervious concrete preparation.
