Description
Technical field
The present invention relates to technical field of concrete, be specifically related to pervious concrete prepared by a kind of foam concrete waste material.
Background technology
Along with expanding economy and the quickening of urban construction, the earth's surface of modern city is progressively covered by building and concrete road surface.Means of transportation, the road of smooth laying bring great convenience to the trip of people easily, but these fluid-tight road surfaces bring many negative impacts also to the ecological environment in city.Owing to the road surface of concrete making lacks water penetration and breathability, rainwater can not permeate the ground, and causes ground flora to be difficult to normal growth due to serious water shortage；The very difficult exchange carrying out heat, moisture with air in air-locked road surface, lacks urban surface temperature, the regulating power of humidity, produces so-called " heat island phenomenon ".Additionally, fluid-tight soil rainwater can not get infiltration, cause subsoil water normally not supplement, and groundwater resources usage amount is increasing, cause earth formation unstable, form ground and cave in.The feature that pervious concrete has loose structure, porosity is big, can permeate rainwater, increases urban groundwater resource, improves urban climate, protects environment, is a kind of Eco-friendly concrete, is widely used in road and parking lot etc. in square, footpath, park.
In recent years, China increasingly payes attention to Building Energy-saving Work, and along with the enforcement with building energy conservation relevant policies, materials for wall reform achieves significantly achievement, and energy-saving material enjoys great popularity.Foam concrete, because of its good characteristic, is widely used in energy-saving wall material.At present, about family more than 800 of foam concrete enterprise of China, wherein, and cast-in-place enterprise about 400, product enterprise about 150, apparatus processing enterprise about 100, foaming agent manufacturing enterprise about 80.About producing the waste material of 10% in foam concrete production process, how foam concrete waste material has been processed into the urgent difficult problem that manufacturing enterprise faces.At present, foam concrete waste material is many to be processed in modes such as accumulation deposit or road fillings and utilizes, and not only occupies the confined space, causes the wasting of resources simultaneously, the significant damage to environment structure.Foam concrete waste recovery is utilized, replaces natural resources to produce pervious concrete, be to protect national resource, improve environment, an important channel of Promote Sustainable Development.
Summary of the invention
For solving the problems referred to above, the invention discloses a kind of low in raw material price, pervious concrete prepared by foam concrete waste material simple and easy to get.The pervious concrete of the present invention has good combination property, and solve foam concrete waste material stores up problem simultaneously, it is achieved that the resource high value added utilization of foam concrete waste material, decreases the use of natural material simultaneously, reduces production cost.
For achieving the above object, technical scheme is as follows:
Pervious concrete prepared by a kind of foam concrete waste material, is made up of the material of following percentage by weight: cement 12-22, water 2.7-8.9, regenerated coarse aggregate 55-75, modifying agent 10-14, water reducer 0.1-0.3；
Described, regenerated coarse aggregate be mean diameter be the foam concrete waste material of 5.5-12mm；
Foam concrete waste material is due to the reason such as do not have strict Classification Management standard, quality control the strictest, the most with the process such as accumulation deposit or road filling and utilization, this low value-added Land use systems not only occupies the confined space, cause the wasting of resources simultaneously, and the significant damage to environment structure.Owing to foam concrete waste material exists substantial amounts of enclosed type foam hole, and there is certain active mineral composition, on the basis of giving full play to its porosity, be remarkably improved the performance of pervious concrete.
Described, modifying agent is by quick lime: calcined alunite forms according to the weight ratio of 1:1；
Described, water reducer is lignosulfonates high efficiency water reducing agent；
Described, cement is 42.5 Portland cements.
Preferably, pervious concrete is made up of the material of following percentage by weight: cement 13.9-19, water 4-7, regenerated coarse aggregate 60.8-71, modifying agent 11-13, water reducer 0.1-0.2.
It is furthermore preferred that what pervious concrete was made up of the material of following percentage by weight: cement 16, water 5.7, regenerated coarse aggregate 66, modifying agent 12.15, water reducer 0.15.
Beneficial effects of the present invention: pervious concrete prepared by the present invention employs substantial amounts of foam concrete waste material, instead of natural gravel, not only solve the problem that a large amount of soil was deposited and occupied to foam concrete waste from stacking, additionally provide a kind of excellent performance, cheap pervious concrete, reduce the exploitation to natural stone, achieve the resource high added value comprehensive utilization of foam concrete waste material, there is obvious economic and social benefit；The pervious concrete of preparation on the premise of meeting comprcssive strength, frost resistance, coefficient of permeability >=3.0mm/s, it is ensured that engineering construction quality, dramatically increase urban groundwater resource, regulate urban climate, improve the ecological environment.
Detailed description of the invention
Principle and feature to the present invention are described below, and illustrated embodiment is served only for explaining the present invention, is not intended to limit the scope of the present invention.
Pervious concrete prepared by a kind of foam concrete waste material, is made up of the material of following percentage by weight: cement 12-22, water 2.7-8.9, regenerated coarse aggregate 55-75, modifying agent 10-14, water reducer 0.1-0.3.
