Description
Technical field
The present invention relates to a kind of pervious concrete, particularly relate to a kind of road pervious concrete and preparation method thereof.
Background technology
Pervious concrete is also known as celluar concrete, permeable terrace, it is a kind of porous light concrete by aggregate, cement and water mixing, it does not contains fine aggregate, mutually bondd by coarse aggregate Surface coating a thin layer cement mortar and form the equally distributed alveolate texture in hole, therefore there is ventilative, permeable and lightweight feature, it is possible to claim non-fine concrete.It is by American-European, Japan and other countries for the defect on the road surface of former urban road, and the one of application can allow rainwater flow into underground, effective recharge of groundwater, alleviate some Urban Environmental Problems of the level of ground water drastically decline etc. in city.And the harm of the environmental pollutions such as ground oil compounds can be effectively eliminated；Meanwhile, it is protection subsoil water, maintaining ecological balance, the excellent pavement material of urban heat land effect can be alleviated；In its benign development being conducive to environment for human survival and the work such as urban rainwater management and water prevention and cure of pollution, there is special significance.
Pervious concrete begins to research and application in the U.S. from the 1970s and 1980s in last century, many countries are all in large-scale popularization, as the road reformation of 90% to be become pervious concrete by Germany's expection in a short time, change and destroy in the past the ground of urban ecology and lay, make pervious concrete pavement depend on to obtain social benefit widely.
But, the performance indications of the pervious concrete prepared by the formula of prior art are not highly desirable, do not reach good water penetration, it is impossible to meet demand.Therefore, a kind of high performance road pervious concrete is produced particularly important.
Summary of the invention
It is an object of the invention to provide a kind of road pervious concrete, particularly relate to a kind of road pervious concrete and preparation method thereof.
The technical scheme is that a kind of road pervious concrete, it is characterised in that the formula of described concrete is aggregate 60～70 parts, sulphate aluminium cement 20～30 parts, sodium silicate 10～15 parts, gelatin 3～5 parts, plastic-steel fabric 0.5～1 part, early strength water-reducing agent 0.1～0.3 part, extender 0.1～0.3 part, accelerator 0.1～0.3 part, coloring agent 0.1～0.3 part, described aggregate is metallurgical slag, gangue, cinder, the mixture of building waste porous aggregate, and the particle diameter of aggregate is 5～20 millimeters.
Further, the preparation method of described concrete is as follows:
Step one: by gelatin with warm water according to 1: 3 dilution mixture；
Step 2: blender stirring is put in described aggregate, sulphate aluminium cement, sodium sulfate, triethanolamine, sodium lignosulfonate, mortar thickening agent, accelerator mixing；
Step 3: uniformly drench in mixture after agitation into sodium silicate emulsion, gelatin solution and proportioning water；
Step 4: the product of step 3 is stirred and heats；
Step 5: after reaching uniform temperature, mixing speed is reduced to original three/carry out in the lump continuously stirred.
Further, the temperature of the warm water of described step one is 80 degree.
Further, the mixing time of described step 2 is 10～15 minutes.
Further, the pouring angle of incidence of described step 3 is 15～20 minutes.
Further, the mixing time of described step 4 is 10～15 minutes, and temperature is heated to 65～70 degree.
Further, the mixing time of described step 5 is 10～20 minutes.
Beneficial effects of the present invention: raw material of the present invention is metallurgical slag, gangue, cinder, building waste; these raw materials are conveniently easy to get in the place of architectural engineering; the recycling of building waste is also used while reducing cost; decreasing the operation of burning, Save Resource Protect Environment kills two birds with one stone.
Sulphate aluminium cement has strong, the most high-strength feature, and its 3 days intensity are equivalent to 28 days intensity of same label portland cement, it is adaptable to repairing rush construction engineering；Owing to this cement series intensity plays fast, therefore in prefabricated components, application can save steam-cured energy expenditure；There is good frost resistance, be widely used in the engineering of winter low temperature construction；
Sodium lignosulfate, has good diffusion, can be dissolved in the water of any hardness, chemistry of aqueous solution good stability, biodegradable.Lignosulphonates have the uneven anionic polyelectrolyte of polydispersity also known as sulphite lignin.Solid product is the free-pouring powder of yellowish-brown, has hygroscopicity.Soluble in water, do not changed by pH value and affected.Aqueous solution be brown to black, have colloid property, the viscosity of solution raises with the increase of concentration.Lignosulfonates are the least to reducing the capillary effect in interface between liquid, and can not reduce the surface tension of water or form micelle.
Sodium silicate another name waterglass, purposes widely, almost throughout each department of national economy.It is used to manufacture the various silicates products such as silica gel, white carbon, zeolite molecular sieve, metasilicate pentahydrate sodium, Ludox, layer silicon and instant powdery sodium silicate, sodium potassium silicate at chemical system, is the base stock of silicon compound.In developed country, the deep processing series of products with sodium silicate as raw material have evolved to more than 50 kinds, and some has been applied to high, precision and frontier sciemtifec and technical sphere.Building trade is used for manufacture quick hardening cement, acid-resistant cement dubbin, soil-solidified-agent, refractory material etc..
The raw material that the present invention chooses not only energy-conserving and environment-protective, and be widely used in this day and age and be conveniently easy to get, the manufacture method of this concrete mainly includes that stirring and leaching are drenched, and easy and simple to handle, fast and easy, the firm long-life, low cost is so there being good development prospect.
