Abstract
The invention discloses an additive for pervious concrete. The additive for the pervious concrete comprises a water reducer, a retarder, a viscosity modifier, an entraining agent and water, wherein the mass ratio of the water reducer to the retarder to the viscosity modifier to the entraining agent to the water is (30-50): (1-3): (0.5-3): (0.3-1.5): (42-60). The invention further discloses the application of the additive for the pervious concrete. The additive for the pervious concrete has the advantages that for the application requirement of the pervious concrete, the additive special for the pervious concrete is provided; after the additive is added to the pervious concrete to be used, the fluidity of the pervious concrete can be improved, premature drying and condensation can be avoided, unloading is facilitated, and the durability and the long-term strength of the previous concrete are improved.
Description
Technical field
The present invention relates to a kind of the reinforcement of concrete admixture and application thereof, particularly admixture and application thereof for a kind of pervious concrete.
Background technology
Pervious concrete is a kind of ecological environment-friendly type concrete, is the concrete with continuous hole that grinds choosing, makes through special process by material, and existing certain intensity, have again certain ventilative water permeability.Pervious concrete is a kind ofly can meet pavement performance, can coordinate symbiosis with physical environment again, the paving material of the comfortable living environment of behaviour class formation, pervious concrete with upper and lower open pore can effectively improve the heat balance on earth's surface, strengthen the circulation of the upper and lower water in earth's surface, city is increased groundwater resource, alleviates tropical island effect, improves urban climate and have great importance.
The successful Application of pervious concrete need possess following some: can be fast discharging obtain certain density from agitator truck, and there is no slurry stream to concrete base; Before maintenance, there is time enough to be constructed, guarantee that pervious concrete can too early drying not condense; There is enough intensity and endurance quality.Reach above requirement, need be regulated by special admixture, and there is no at present a kind of special additive of pervious concrete, in Practical Project, multiplex normal concrete admixture replaces, thereby cause, pervious concrete is dry, time of coagulation is too fast, be difficult for discharging, poor durability, the problem such as later strength is low, serviceability is poor, give and produce and the workmen brings inconvenience.Add the pervious concrete performance perameter of normal concrete admixture to be generally: spillage 3.5%, 11: 45 presetting period, 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 purpose of this invention is to provide a kind of admixture of pervious concrete special use, make pervious concrete there is 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: mix at 25: 5: 61, obtain when the tawny thick liquid occurring 70～100 ℃ of reactions.Water reducer is for increasing the density of pervious concrete, and guarantees that pervious concrete has enough rheologicals, contributes to the transport mixer discharging.
Described retardant is amino trimethylammonium phosphoric acid, tricarboxylic one or both mixing of phosphine butane.Retardant can increase the usable time of building operation, makes pervious concrete that rapid drying or coagulation phenomena early not occur.
Described viscosity modifier is a kind of of polyacrylamide, starch, Walocel MT 20.000PV ether.Viscosity modifier contributes to improve density, the water-retentivity of pervious concrete, reduces slurry and runs off, and can improve the 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 improve the pervious concrete mobility, improves its serviceability, contributes to strengthen pervious concrete freeze-thaw-weather resistance simultaneously, extends its work-ing life.
The application of admixture for above-mentioned a kind of pervious concrete, 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-purpose admixture is provided, after adding pervious concrete to use, can improve the mobility of pervious concrete, prevent that too early drying from condensing, so that discharging, weather resistance and later strength also are improved.
