Description
Technical field
The present invention relates to technical field of concrete, and in particular to a kind of pervious concrete and preparation method thereof.
Background technology
In modern urban construction, most road surface or slope surface all use stone slab, cement square bricks, pipe duct etc. to harden road
Face is a lack of respiratory, absorbs heat and permeates the ability of rainwater although the road surface and slope surface of hardening are neatly durable.Therefore
Many ecological environment problems are brought, the time rainwater that such as rains is blocked the supplement of underground water, and level of ground water is difficult to,
With the loss of rainwater, urban surface drying aggravation is easy to form " tropical island effect ", aggravates city raised dust pollution;On the other hand,
Rainfall is big, and municipal drainage is obstructed, be easy to cause Urban flood, the serious consequence such as traffic jam is caused, for river two
For the slope surface of bank, the protective slope structure and material of hardening can cause river water not smooth, it is difficult to infiltrate, reduced velocity flow causes Ha Noi to give birth to
The deterioration of state has a serious impact the animals and plants of surrounding.Again, the road surface of hardening and slope surface color are relatively simple, unfavorable
In the landscape ecological construction of diversification.
Pervious concrete is a kind of ecological, environmental protective concrete, and pervious concrete is while meeting intensity requirement, it is also necessary to
Perforation hole centainly is kept to meet the requirement of water penetration, therefore is also wanted other than selecting suitable raw material when preparing
Achieve the purpose that proof strength and porosity by mix-design and preparation process and additive.Therefore, permeable coagulation
Soil be it is a kind of not only meeting Pavement Performance, but also the road surface slope surface coordinating material mutually coordinated with natural environment, for improving earth's surface heat
Balance, flow is logical up and down for enhancing earth's surface, alleviates tropical island effect and is of great significance.But big logarithm pervious concrete at this stage
Preparation method it is complicated, be unfavorable for practical application.
Invention content

Preferably, the pervious concrete includes according to mass fraction:10 parts of cement, 38 parts of aggregate, biomass carbon 1.2
Part, 1.2 parts of colorant, 0.3 part of water-reducing agent and 2.7 parts of water.
Preferably, the cement is 42.5 grades of Portland cements.
Preferably, the aggregate size is the simple grain grade rubble of 5~25mm.
Preferably, the water-reducing agent is high performance water reducing agent of polyocarboxy acid.
Second aspect of the present invention provides a kind of preparation method of pervious concrete.Specifically, the method includes following
Step:
It is sufficiently mixed Step 1: water-reducing agent and water are stirred 10~20min, aggregate surface is sprayed in a manner of spray, made
Aggregate must be mixed;
It is sufficiently mixed Step 2: cement, biomass carbon and colorant are stirred 30~40min, intermixture is made;
Step 3: intermixture is sufficiently stirred with aggregate is mixed, pervious concrete is made.
Preferably, it is uniformly sprayed on the aggregate surface by different level after water-reducing agent in the step 1 and water being mixed.
Preferably, the mixing aggregate is to be sufficiently humidified so as to and flow out state without water droplet.
Preferably, the pervious concrete is that intermixture mutually wraps up and with aggregate is mixed without stream shape slurry outflow shape
State.
The method of the present invention has the following advantages that:
The pervious concrete of the present invention is cooperated by intermixture with aggregate is mixed, and the equally distributed honeycomb in hole is formed
Shape structure can in time absorb water, water storage and infiltration to enhance the aeration and seepage of water of pervious concrete in the rainy day
The harmful substance in runoff water is filtered and adsorbed simultaneously, to have the function that purifying ecological environment, and environment can be adsorbed
In noise, solve that urban surface hardening, Ecological Slope destroys, atmospheric air circulation is unsmooth, noise pollution and water to a certain extent
The ecological problems such as soil loss;
Secondly, pervious concrete performance of the invention is higher, and various colors can adapt to various municipal works, Landscape
Sight and Ecological Road etc., there is unique artistry and appreciation.
