Description
Technical field
Field is manufactured the present invention relates to concrete, more particularly to a kind of modified pervious concrete formula.
Background technology
Permeable concrete ground surface material belongs to environment-friendly type, Ecotype Concrete material, with water penetration and gas permeability, its
Basic composition material and difference of the common concrete material without essence.Except that normal concrete always subtracts by every means
Few porosity, so that its is closely knit, reaches high intensity and the purpose of high-durability, and permeable concrete is by using special material
Material formula, while Pavement Condition requirement is met, its structural porous can be realized and it is continuous the characteristics of, make it have good
Water penetration.When rainfall is concentrated, rainwater can in time be permeated the ground by interconnected pore, reach rapid draining and supplement
The purpose of groundwater resources, is equipped with corresponding rainwater-collecting facility, can be with saving water resource.
In terms of engineer applied, existing numerous engineering employs pervious concrete pavement, for example, than fairly large using dew
In aggregate pervious concrete pavement case history, there is Beijing Olympic engineering, undisguisedly material is saturating more than 100,000 m2 using area of always mating formation
Water coagulation soil surface, also uses in Shanghai World's Fair construction project and undisguisedly expects pervious concrete more than 100,000 m2, and Xi'an is bright greatly
The park of palace engineering and landscape Study on principle of square design have more than 30 ten thousand m2 undisguisedly to expect pervious concrete pavement, Xi'an world flower fair scape
Engineering design is seen more than 200,000 m2 porous pavement etc., the application of middle and small scale is even more innumerable.
Compared with foreign countries, the pervious concrete research of China is still uneven with application development, is mainly manifested in following several
Individual aspect：1st, the composition Study to pervious concrete is deep not enough, to physical and mechanical property and durability and constitutive relation
Research also lack systematicness.2nd, industrialized production and big machineryization construction gap compared with external are larger, at present still with people
Based on work and small-sized machine, concrete is still that based on being prepared in situ, industrialized production is also not implemented.3rd, to the construction of concrete
Method is relatively simple, identical with the construction method of normal concrete without any difference.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of good modified pervious concrete formula of using effect.
In order to solve the above technical problems, the technical scheme is that：A kind of modified pervious concrete formula, it is innovated
Point is：Fraction proportioning by weight is made up of following components：
200-350 parts of cement；
500-700 parts of sand；
50-100 parts of second class powered coal ash；
Discarded object 15-34 parts of imitation frosted glass of section；
15-30 parts of reinforcing agent；
20-46 parts of binder materials；
170-190 parts of pulp-water；
36-85 parts of polycarboxylate water-reducer；
Super slow agent 3.85-5.1 parts；
90-160 parts of slag powders；
1500-1700 parts of rubble.
Further, the miberal powder grade is more than S95 grades.
Further, the pulp-water concentration is between 10%-15%.
The advantage of the invention is that：Match somebody with somebody principle using the level of rubble, adjust the hole of its pervious concrete, subtracted with polycarboxylic acids
Aqua reduction glue, which when adds reinforcing agent, increases the intensity of pervious concrete, and intensity and water penetration requirement can be so met again.
Make road surface closely knit using above-mentioned construction method, aggregate is firmly bonded, surfacing, improve speed of application, effectively ensure engineering
Quality.
A kind of formula for concrete that the present invention is provided, it is cheap, make simple, emphasize height, patience long, with the addition of outer
It is the best modified pervious concrete formula of in the market plus agent enhances the fastness of concrete.
