Abstract
The invention discloses a kind of pervious concrete and preparation method thereof, the concrete compares raw material by following quality：Cement 350 450, coarse aggregate 1,200 1500, adhesive 30 50, polypropene staple 30 60, short steel fibre 50 100, admixture 50 150, additive 30 50 and water 150 200 form.Perspective concrete prepared by the present invention has the characteristics that resistance to compression, bending resistance, excellent in cushion effect.
Description
Technical field
The present invention relates to a kind of pervious concretes and preparation method thereof, belong to technical field of concrete.
Background technology
Pervious concrete be it is a kind of rainwater can be allowed to flow into underground, effective recharge of groundwater, the level of ground water for alleviating city is anxious
Some Urban Environmental Problems of play decline etc..Meanwhile it is protection underground water, maintaining ecological balance, urban heat island effect can be alleviated
It should, promote the excellent pavement material of surface water cycle, be conducive to benign development and the urban rainwater of environment for human survival
Reason improves in the work such as urban development secondary environment problem, has special significance.General concrete road surface permeability rate
Good low strength, and intensity reaches requirement, water penetration can not just ensure, these two aspects performance is difficult to take into account, it is difficult to a wide range of
Using.
The content of the invention
The technical problem to be solved by the invention is to provide it is a kind of can improve resistance to compression, bending resistance, impact strength it is permeable
Concrete and preparation method thereof.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of pervious concrete, the concrete compare raw material by following quality：Cement 350-450, coarse aggregate 1200-1500, glue
