Abstract
The invention discloses a kind of method for improving porous concrete product hole anti-clogging ability；This method is by the way that molding porous concrete product is immersed in the surfactant solution, surfactant is set to adhere to form new surface texture in porous concrete product pore surface, to improve the adhesive ability for reducing fine particle in hole, so as to effectively prevent tiny particle from blocking pervious concrete；The present invention can solve the blockage problem that current porous concrete product is generally faced using process, can extend the service life of porous concrete product, ensure the water permeable ability of porous concrete product.
Description
Technical field
The invention belongs to building material technical field, and in particular to one kind improves porous concrete product hole anti-clogging energy
The method of power.
Background technology
Permeable concrete is a kind of ecological method environment-friendly concrete, is that one kind has continuous aperture by special process is manufactured
The concrete of gap；Not only there is certain intensity, but also have certain ventilative water permeability.Permeable concrete, which is mated formation, can alleviate city
Rain flood, reduces rainy day skidding, dazzle, improves the security and comfort of running car, sqouynd absorption lowering noise, alleviates urban heat island effect
Should.
But general porous concrete product road surface or water-permeable brick, due to the requirement of water penetration, porosity generally compared with
Greatly, after pervious concrete pavement is built up, because of a large amount of suspended particulates such as mud contained in the rainwash of the reasons such as rainfall generation
Sand, chip etc. can be entered constantly in the hole of porous concrete product with current, pore plugging be caused, so as to cause road surface
Permeance property reduces the drain function for being difficult to play porous pavement, shortens porous concrete product service life of road surface, causes
Waste economically.
Also there are various discussions for this way to solve the problem at present, be concentrated mainly on from porous concrete product road surface
Structure and source material mixture ratio etc. solve the problems, such as.
To solve the above-mentioned problems, the present inventor after various experiments and analysis testing result by having found, above problem production
The reason for raw one is important is due to that the porosity of pervious concrete itself is larger, and tamper can be detained hole during use
It is interior.Therefore, the present inventor is from material angle, by the way that the porous concrete product of forming is immersed in some surface-actives
In agent solution, surfactant adheres to form new surface texture in pervious concrete pore surface, and it is fine to be effectively improved reduction
Adhesive ability of the particulate matter in hole, so as to avoid tamper from being trapped in pervious concrete hole, with reach prevent it is permeable
Concrete block, it is ensured that its draining it is unobstructed.
The content of the invention
The object of the present invention is to provide a kind of method for improving porous concrete product hole anti-clogging ability.
The method of the present invention includes：It is molded and is conserved to the porous concrete product of 28 day age by preparing, is immersed in surface
In activator solution 24 it is small when；
The surfactant is one kind in following material：
(1) organic silicon emulsion class surfactant, solid content are 25-40%；
(2) polypropylene esters emulsification surfactants, mass percent concentration are 0.5-5%；
(3) polyethylene esters emulsification surfactants, mass percent concentration are 0.5-5%；
(4) paraffin wax emulsions class surfactant, solid content are 30-50%；
Using surfactant solution soak method be：
1) water soluble surfactant active's organic silicon emulsion
It is 1 in mass ratio by surfactant and water:8—1:10 ratio mixing, is configured to surfactant solution, will
Prepare molding concrete product be completely soaked wherein 24 it is small when；
2) water-insoluble surfactant polypropylene esters lotion, polyethylene esters lotion, paraffin wax emulsions
By the alcoholic solution in mass ratio 1 that surfactant and mass concentration are 75%~95%:8—1:10 ratios mix
Be formed uniformly mixed solution, will prepare molding concrete product be completely soaked wherein 24 it is small when.
Porous concrete product prepared by the present invention is passed through with normal concrete product in the case where other conditions are identical
Overtesting is proved to final anti-clogging result：Product of the present invention is far superior to common porous concrete product.
The condition of present invention selection surfactant：
A. there is good dispersiveness：It can be uniformly dispersed in pervious concrete；
B. there is good compatibility：Keep pervious concrete original raw material and proportioning, process for producing constant, ` tables
Face activating agent can coexist with other raw materials of pervious concrete, and chemical change does not occur, to the mechanical property shadow of pervious concrete
Ring very little；
C. there is good hydrophobicity：The water absorption rate of pervious concrete can be greatly lowered；
D. there is good application property：Powder powder or liquid surfactant can be directly added into pervious concrete raw material
Using or immersion, be not required to extra construction technology.
The principle of the invention：The present invention is keeping the original material of common pervious concrete and proportioning, process for producing constant
On the basis of, common porous concrete product is soaked with prepared surfactant solution, surfactant can be dispersed
In porous concrete product, including it is dispersed in the pore surface on inside porous concrete product and surface.During rainfall, due to hole
The surfactant component on gap surface exists, and the surface texture of the internal void of pervious concrete is improved, reduced fine
Adhesive ability of the particulate matter in hole, so as to reduce the tamper being trapped in hole, ensures the permeable energy of pervious concrete
Power.
The advantages and features of the present invention：
1. the present invention prevents from blocking from the surface texture for improving pervious concrete internal void, solve permeable at present mixed
The anti-clogging technical barrier that solidifying soil promotes and applies.
2. the method for the present invention can extend the service life of pervious concrete；With good social and economic benefit.
