Description
Technical field
The invention belongs to building material technical fields, and in particular to a kind of ecological permeable bricks and preparation method thereof.
Background technique
With the rapid development of China's economy and greatly developing for urbanization, greenery patches originally is by large-scale ground pavement
Replace, " the city desert " of formation considerably increase Permeable stratum area, prevent urban rainwater is from back to nature, as a result, city
City's underground water largely reduces, the danger for having urban architecture to sink；And heavy rain is met when city is prominent, rainwater on road surface can not quickly seep
Leakage causes to municipal drainage facility and greatly bears and easily send out into urban waterlogging.At the same time, the road of mating formation of large area
Face weakens the respiratory function in city, will cause " tropical island effect ", reduces city comfort level and causes urban ecological system unbalance,
Therefore water-permeable brick as a kind of good water permeable paving material start by more and more attention has been paid to.
Although currently, asking for above-mentioned municipal drainage difficulty can be solved to a certain extent by having researched and developed some water-permeable bricks
Topic, but a large amount of rainwater directly passes through water-permeable brick and infiltrates into ground, and ground is be easy to cause to loosen, thus water-permeable brick is needed to have
Stable porosity, good compression strength and fracture resistance.
Summary of the invention
The purpose of the present invention is overcoming the porosity of existing water-permeable brick unstable, compression strength and fracture resistance is bad asks
Topic.
For this purpose, the embodiment of the invention provides a kind of ecological permeable bricks, including surface layer and initial bed, the raw material of the surface layer

25%, big stone 30~35%, yellow ground 20~25%, the second additive 0.5~2%, surplus is water.
Further, the partial size of the handstone is 1~5mm, and the partial size of big stone is 5~10mm, the handstone and
The mass ratio of big stone is 1.5:1~1.7:1.
Further, first additive is one or more of curing agent, antioxidant and ultraviolet absorbing agent
Mixture, the second additive are water-reducing agent.
Further, the raw material of the surface layer further includes the pigment that mass fraction is 0.5~1%.
Further, the raw material of the initial bed further includes fiber and cementitious material, and the cementitious material is by house refuse
Flying ash, slag, alkali-activator are constituted.
Further, the surface layer with a thickness of 5~8mm, the initial bed with a thickness of 50~55mm.
In addition, including the following steps: the present invention also provides the preparation method of above-mentioned ecological permeable bricks
1) surface layer mixed slurry is prepared
Each raw material of surface layer is mixed evenly in mass ratio, obtains surface layer mixed slurry；
2) initial bed mixed slurry is prepared
Big stone and handstone are ground after first cleaning handstone and big stone respectively and its partial size is screened, then
Other raw materials of the handstone filtered out and big stone and initial bed are mixed evenly in mass ratio, obtain initial bed
Mixed slurry；
3) initial bed mixed slurry prepared by step 2) is put into molding die, is tamped through vibration, after its preliminary solidification,
Surface layer mixed slurry prepared by step 1) is added in molding die again, vibration is tamped, and is demoulded after standing curing molding, natural
5~10 days are conserved under state to get ecological permeable bricks.
Compared with prior art, beneficial effects of the present invention:
