Abstract
The invention discloses a kind of high-performance foam light soil foaming agent and preparation methods, it is applicable in ordinary portland cement, wherein high-performance foam light soil foaming agent includes water, anionic surfactant, nonionic surface active agent, water-reducing agent, retarder, foam stabilizer, thickener and colorant, it is by mass percentage water 10%~50%, anionic surfactant 10%~30%, nonionic surface active agent 5%~20%, water-reducing agent 10%~50%, retarder 5%~20%, foam stabilizer 5%~10%, thickener 2%~8%, colorant 0.5%~2%.The adaptability of high-performance foam light soil foaming agent of the present invention and cement, mineral admixture and additive is good, the foam uniform and smooth of formation, resistance to highly basic, half-life are long, it mixes and stirs that the Foam lightweight soil flow valuve to be formed is controllable, contraction distortion is small with cement slurry, ensure that the quality and durability of the Foam lightweight soils filling body such as Bridge back wall, soft soil roadbed, Roadbed widening, side slope protection.
Description
Technical field
The invention belongs to the application fields of highway engineering Foam lightweight soil more particularly to Foam lightweight soil to return in Bridge back wall
It fills out, treatment of soft foundation, Roadbed widening, side slope protection etc. application.
Background technique
Domestic Bridge back wall routinely fills the problems such as causing serious vehicle bump at bridge ends and high maintenance cost, influences safety
Traveling and highway long term life.Cast-in-place foamed light soil has Lightness, vertical property, high fluidity, bulk density and intensity adjustability
And construct the features such as convenient, it is used for back filling behind abutment, the variable gradient of relative settlement between bridge (culvert) and roadbed can be alleviated significantly, made
The variation of relative settlement is slowly changed, is homogenized between abutment, the jump being inherently eliminated between the bridge in highway (culvert) and roadbed
Vehicle problem.And the soil lateral pressure that the Foam lightweight soil generates is small, and bridge (culvert) will not be made to shift, and rises indirectly to bridge (culvert)
Protective effect to a certain extent.In recent years, domestic Foam lightweight soil was in Bridge back wall backfill, treatment of soft foundation, Roadbed widening, side
Slope, which is protected, is promoted the use of, and good result is achieved.
The domestic patent about Foam lightweight soil foaming agent mainly has at present: China State Construction Engrg. Corp. Ltd.
Disclose within 2013 a kind of composite water cement foaming agent and preparation method thereof (number of patent application: 201310292824.6).The party
Method describes a kind of foaming agent of anionic, and the foam which generates is stablized, but foam size is bigger than normal.Hubei University
Disclose within 2016 a kind of Foam lightweight soil foaming agent and preparation method thereof (number of patent application: 201610179132.4).The party
Method reacts the mother liquor that foams of attaining the Way using discarded animal cutin, hair, by high temperature corruption, and this method prepares blowing agent stability
Difference, easily stench breed bacterium, the defects of foam size is big.It is more about the report that hydrogen peroxide is foaming agent, it is still, such
Invention product is more sensitive to temperature, catalyst and pH value, especially reacts extremely difficult control under hot environment.Such invention product one
As be used for quick hardening sulphoaluminate cement, foam size size and cement setting time, cement more demanding to cement setting time
Thin pulp viscosity and exothermic heat of reaction amount have relationship, and hardening Pore stability is difficult to effectively control.Discovery is investigated, at present state
It is interior about Foam lightweight soil foaming agent, have foam stability is poor, alkali resistance is poor, foam is not fine and smooth enough, half-life is short etc.
Disadvantage.
Foam lightweight soil foaming agent is a kind of new additive of light high strength concrete, it has following technology because of this
It is required that: (1) each component substance stablize, each other without physical-chemical reaction, and each component similar density, it is easy to form uniform mixed
Close object；(2) to hydrated reaction of cement without negative effect, or even the effect that tool regulates and controls setting time and strives for；(3) foam size can
Control；(4) wide adaptation range, it is especially insensitive to different cultivars cement, mineral admixture and ambient temperature and humidity；(5) usage amount can
