Description

A kind of pervious concrete admixture and application thereof
Technical field
The present invention relates to a kind of the reinforcement of concrete admixture and application thereof, particularly a kind of pervious concrete admixture and application thereof.
Background technology
Pervious concrete is a kind of ecological environment-friendly type concrete, and be the concrete with continuous hole grinding choosing by material, make through special process, existing certain intensity, has again certain ventilative water permeability.Pervious concrete is that one can meet pavement performance, again can with physical environment coordinated growth, the paving material of the comfortable living environment of behaviour class formation, the pervious concrete with upper and lower open pore effectively can improve the heat balance on earth's surface, strengthen the circulation of earth's surface upper and lower water, groundwater resource are increased to city, alleviates tropical island effect, improve urban climate and have great importance.
The successful Application of pervious concrete need possess following some: can discharging obtain certain density from agitator truck fast, and there is no slurry stream to concrete base; There is time enough to construct before maintenance, guarantee the drying condensation that pervious concrete can not be too early; There is enough intensity and endurance quality.Reach above requirement, need be regulated by special admixture, and there is no a kind of special additive of pervious concrete at present, in Practical Project, multiplex normal concrete admixture replaces, thus cause that pervious concrete is dry, time of coagulation is too fast, not easily discharging, the problems such as poor durability, later strength are low, serviceability is poor, bring inconvenience to production and workmen.The pervious concrete performance perameter adding normal concrete admixture is generally: spillage 3.5%, the presetting period 11 time 45 points, porosity 28.8%, coefficient of permeability 1.8mm/s, ultimate compression strength 28.4MPa, freeze-thaw-cycle index 140 times.
Summary of the invention
Goal of the invention: for the problems referred to above, the object of this invention is to provide the admixture that a kind of pervious concrete is special, makes pervious concrete have good mobility, weather resistance, later strength; The application of this admixture is provided simultaneously.
Technical scheme: a kind of pervious concrete admixture, comprise water reducer, retardant, viscosity modifier, air entrapment agent, water, each constituent mass is than being water reducer: retardant: viscosity modifier: air entrapment agent: water=(30 ~ 50): (1 ~ 3): (0.5 ~ 3): (0.3 ~ 1.5): (42 ~ 60).
Described water reducer is poly carboxylic acid series water reducer, its component comprises polyoxyethylene glycol, butyl methacrylate, methyl methacrylate, alkene ether polyoxyethylene, maleic anhydride, water, each component is polyoxyethylene glycol in mass ratio: butyl methacrylate: methyl methacrylate: alkene ether polyoxyethylene: maleic anhydride: water=2: 2: 5: 25: 5: 61 mixing, obtain to when there is tawny thick liquid 70 ~ 100 DEG C of reactions.Water reducer for increasing the density of pervious concrete, and guarantees that pervious concrete has enough rheologicals, contributes to transport mixer discharging.
Described retardant is one or both mixing of amino trimethylammonium phosphoric acid, phosphine butane tricarboxylic acid.Retardant can increase the usable time of building operation, makes pervious concrete that rapid drying or early coagulation phenomena not occur.
Described viscosity modifier is the one of polyacrylamide, starch, Walocel MT 20.000PV ether.Viscosity modifier contributes to the density, the water-retentivity that improve pervious concrete, reduces slurry and runs off, and can improve pervious concrete surface durability.
Its component of described air entrapment agent and quality proportioning are sodium lauryl sulphate: stearic acid: sulfonated melamine=(75 ~ 80): (10 ~ 15): (10 ~ 12).Air entrapment agent contributes to improving pervious concrete mobility, improves its serviceability, contributes to strengthening pervious concrete frost-proof test simultaneously, extends its work-ing life.
The application of above-mentioned a kind of pervious concrete admixture, the consumption of described admixture in pervious concrete is 1 ~ 3% of gelling material quality.
Beneficial effect: compared with prior art, advantage of the present invention is the application requiring for pervious concrete, special admixture is provided, after adding pervious concrete use, the mobility of pervious concrete can be improved, prevent too early drying condensation, so that discharging, weather resistance and later strength are also improved.
