Abstract
The invention discloses an organosilicone waterproof agent for multifunctional high-performance concrete.The organosilicone waterproof agent is composed of organosilicone, naphthalene sulfonated formaldehyde condensate sodium salt, triethanolamine, sodium lignin sulfonate or calcium lignin sulfonate, citric acid, sodium thiosulfate and water.The organosilicone waterproof agent is a multifunctional liquid-state waterproof agent integrating efficient waterproofness, water reduction and pumping and having slight expansion effect and can meet the technical requirements on pumping construction of large-flow waterproof concrete.The organosilicone waterproof agent can remarkably improve early strength of mortar and concrete, flowability and plasticity maintaining capability and is suitable for waterproof mortar, waterproof concrete and pumping concrete of underground engineering, dykes and dams, building engineering and traffic engineering.
Description
Technical field
The present invention relates to building material field, be specifically related to a kind of the reinforcement of concrete waterproofing agent of organosilicon.
Background technology
Although the waterproofing agent of current construction market application is of a great variety, but is broadly divided into powder body and liquid waterproof agent two kinds.Multifunctional water-proofing agent for concrete domestic at present be all powder waterproofing agent and its incorporation higher, account for the 8 ~ 12% of cement weight.Powder waterproofing agent and extender etc. mix and primarily serve anti-cracking waterproof effect in concrete.Known powder waterproofing agent exists a lot of not enough when application, as when adopting pumping construction concrete then must other additive of compound, such as pumping admixture, water reducer etc., construction technical requirement could be met.In addition, need special messenger to feed intake, dust is big, labor intensity is high, easily because measuring inaccurate and to cause accident resulting from poor quality of projects etc. be also that produced problem often applied by powder body waterproofing agent.
The liquid repellent agent of domestic application, mainly has ferric oxide class waterproofing agent, fatty acid and inorganic aluminum salt waterproofing agent etc., and incorporation is about 2 ~ 3%.They mix the water proof anti-seepage effect that primarily serves in concrete, do not have the effects such as pumping, expansion, apply relatively powder body waterproofing agent convenient.But current liquid repellent agent function is more single, as being added with the additive such as pumping admixture or water reducer at Concrete Pumping Construction.And there is the waterproofing agent of single water-proof function and extender can not meet the needs of development of the situation.Along with the development of Building Trade in China, skyscraper and underground civil defense engineering increase year by year.Owing to the maximization of engineering structure, complication and concrete production and construction technology develop to mechanization, modernization and commercialization increasingly, propose more technology requirement for mixing the rigidity water-proofing material in concrete.
Summary of the invention
It is an object of the invention to overcome the deficiency of above-mentioned waterproofing agent, there is provided a kind of collect high-effective water-proof, diminishing, be pumped to one liquid repellent agent, mortar, concrete early strength can be dramatically increased, increase mobility, improve guarantor and mould ability, and the pumping construction technology requirement of big fluidised form water-proof concrete can be met
For achieving the above object, the present invention adopts the following technical scheme that
A kind of multifunctional high-performance the reinforcement of concrete waterproofing agent of organosilicon, it is characterised in that: it is made up of the component of following weight ratio: organosilicon 20 ~ 35%；Naphthalene sulfonic acid-formaldehyde condensation product sodium salt 5 ~ 20%；Triethanolamine 0.9 ~ 1.6%；Sodium lignin sulfonate or calcium lignosulfonate 5 ~ 15%；Citric acid 0.5 ~ 1.5%；The water of sodium thiosulfate 5% ~ 15% and surplus.
Further, organosilicon described in multifunctional high-performance the reinforcement of concrete waterproofing agent of organosilicon of the present invention is methyl silicon sodium alcoholate.
Further, in multifunctional high-performance the reinforcement of concrete waterproofing agent of organosilicon of the present invention, contained components by weight is: organosilicon 25 ~ 30%；Naphthalene sulfonic acid-formaldehyde condensation product sodium salt 7.5 ~ 13%；Triethanolamine 1.2 ~ 1.4%；Sodium lignin sulfonate or calcium lignosulfonate 8 ~ 12%；Citric acid 1.0 ~ 1.3%；The water of sodium thiosulfate 7.5% ~ 10% and surplus.
The methyl silicon sodium alcoholate of the present invention is its water repellent component, and it is the important component of multifunction water repellent admixture.Mix water repellent component, many colloid can be formed and conjugate be filled in concrete with reaction at concrete by synthesizing, plug the capillary porosity in concrete, reduce hole XISHUAI, improve concrete degree of compaction and impermeabilisation ability.
The naphthalene sulfonic acid-formaldehyde condensation product sodium salt of the present invention is its fluidized composition, and it is a kind of surfactant, and its effect is fully dispersed cement, makes the moisture of cement group parcel discharge.When not increasing concrete water-cement ratio, the concrete slump can be dramatically increased, thus ensureing that neither affecting concrete intensity can meet again the requirement of Concrete Pumping Construction.
Sodium lignin sulfonate or calcium lignosulfonate are its diminishing component.It can being greatly reduced the concrete ratio of mud, reducing porosity, increasing concrete density thus being greatly improved concrete intensity and impermeability.
Its slow setting of the citric acid of the present invention is protected and is moulded component, can suitably extend concrete just, final set time ask, reduce concrete slump-loss, meet Concrete Pumping Construction requirement and do not affect concrete early stage and later strength development.
Non-irrigated strong and strengthening action structure adjusting mortar, concrete each age strength of the triethanolamine of the present invention, meanwhile, also has the effect improving mortar, concrete density.
The high early strength function of the sodium thiosulfate of the present invention can solve the deficiency that former waterproofing agent of organosilicon is early low by force.
The present invention, after compound, gives full play to effect of each component, it is achieved the multifunction of waterproofing agent and high-performance.
The concrete waterproofer of the present invention succeeds in the commerical ready-mixed concrete test of many times of underground engineering, it is not necessary to pumping admixture can directly pump.7 days comprcssive strength is not less than 150,28 days comprcssive strength and is not less than 135.Infiltration ratio is below 30%.Comprcssive strength loss ratio is not more than 50.Mass loss rate is not more than 70.All indexs of additive all meet the technology requirement of JC474-1999 " mortar, concrete waterproofer " Grade A.
