Description
Technical field
The invention belongs to technical fields prepared by concrete, provide a kind of bagasse pervious concrete and preparation method.
Background technology
With the lasting propulsion of urban construction, natural soils are constantly by both waterproof or air-locked compact-type concrete institute
A series of the problem of covering, influence human survival qualities of the life such as " urban heat land effect ", urban waterlogging, groundwater resources deterioration
Gradually show.It is advocated energetically for appeal problem country and builds sponge city, it is desirable to which city can in time be inhaled as sponge
It accepts the enemy's surrender rain, improves city itself and adjust and the ability of reply climate change.The most important ring in sponge city is built in propulsion
The good ecological permeable concrete of water-permeable and air permeable performance is vigorously promoted the use, the effect of natural soils water conservation, water purification is given full play to.
Permeable concrete is also known as blown-out concrete, is a kind of porous light made of aggregate, cement and water mixing
Matter concrete, it is free of fine aggregate, is mutually bonded by coarse aggregate surface cladding a thin layer cement mortar and is formed hole and be uniformly distributed
Honeycomb structure.The main purpose of pervious concrete application is water resource, environmental protection and prevents the flood during Urban Rain
Damage caused by waterlogging is done harm to, and the mode of action is by itself and the infiltration of base original place or to infiltrate into the moisture on its surface in soil nearby, from
And safeguard the level of ground water in some areas, purify water, reduce the drainage load of sewerage system and the rainwater of low laying areas
Aggregation.
The group of permeable concrete and common concrete material, which is closed, to be made a big difference, and coarse aggregate size is single,
The special material combination the characteristics of determining pervious concrete for not mixing or mixing less fine aggregate be with the gap being largely connected to,
It is high with permeability, water-holding capacity is strong, absorbing sound and lowering noise, good dicoration, ease for maintenance, freeze-thaw resistance, durability, high heat dissipation
The advantages that property and eco-environmental prote.For water-permeable cement concrete, to synthesize and coordinate water-cement ratio-rheological characteristic-intensity-porosity it
Between relationship, can just make prepared water-permeable cement concrete on the one hand there is required water permeable ability in this way, on the other hand
With good intensity.
At present certain effect has been achieved in terms of pervious concrete, especially modified enhancing pervious concrete both at home and abroad.
Wherein sliding dawn et al. has invented a kind of polymer pervious concrete for building sponge city（Chinese invention patent application number
201610566934.0）, every cubic metre contains the following raw material：370 ~ 420kg of cement；Rubble 1500kg, ballast grain sizes be 5 ~
10mm；The silica sand of grain size 0.5mm, dosage are the 5% ~ 10% of cement weight, and silica sand particles are ellipse；Mixing intensity enhances
Agent, dosage are the 5% ~ 8% of cement weight；The weight ratio of water, water and cement is 1：0.27~1：0.33；Polymer compound formulation,
Dosage is the 3% of cement weight；Polymer compound formulation is formed by the raw material mixture of following weight proportion：Epoxy resin 12
Part, 0.6 part of chlorinated paraffin, 1.6 parts of montmorillonite powder, 1.2 parts of polyacrylamide, acrylic acid-acrylic acid hydroxypropyl ester copolymer 0.3
Part；The polymer pervious concrete of the invention, the half unimpeded gap and dead air space generated in forming process is few, unimpeded gap
More, water permeability is good, and intensity is high；The polymer of introducing makes Behavior of Hardened Cement Paste have certain flexibility, and non-deformability is good, has preferable
Anti-freezing property.In addition, Zheng Li has invented by force a kind of pervious concrete（Chinese invention patent application number 201710374266.6）,
Including following components：1500 ~ 1700 parts of coarse aggregate；300 ~ 550 parts of cement；90 ~ 120 parts of water；30 ~ 80 parts of additive；Mesoporous material
50 ~ 150 parts of material；150 ~ 220 parts of reinforcing fiber；The invention has the following advantages and effect：First, mesoporous material in pervious concrete
Glued layer is formed in coarse aggregate particle after material, reinforcing fiber and cement mixing, the reinforcing fiber in glued layer passes through mesoporous
Material connects, and forms reticular structure, improves the intensity of pervious concrete；Second, it is netted in coarse aggregate particle surface glued layer
Structure so that pervious concrete has higher mechanical property at high temperature, improves the high temperature resistance of pervious concrete；The
Three, coarse aggregate uses single-grade, makes pervious concrete that there is excellent water permeability, dewatering and noise reduction to adjust earth's surface humiture
Etc. ecological functions, environmental protection achieved the effect that good water permeability, ecological, environmental protective, intensity height, high temperature resistant, had a wide range of application.
As it can be seen that pervious concrete in the prior art is because there are more connected holes, generally existing compactness is poor, causes whole
Body low strength exists simultaneously slurry adhesive force deficiency, and the problem of easily sinking to the bottom, these problems hinder pervious concrete significantly
Promotion and application.
