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 water-resisting agent of current construction market application is of a great variety, be mainly divided into powder and liquid waterproof agent two kinds.Multifunctional water-proofing agent for concrete domestic is at present all pulvis water-resisting agent and its incorporation is higher, accounts for 8 ~ 12% of cement weight.Pulvis water-resisting agent and swelling agent etc. mix in concrete and mainly play anti-cracking waterproof effect.Known pulvis water-resisting agent exists a lot of not enough when applying, as then must other admixture of compound when adopting pumping construction concrete, as pumping agent, water reducer etc., could meet construction technical requirement.In addition, needing special messenger to feed intake, dust is large, labour intensity is high, easily being forbidden and causing accident resulting from poor quality of projects etc. to be also that produced problem often applied by powder water-resisting agent because measuring.
The liquid repellent agent of domestic application, mainly contain Indian red class water-resisting agent, fatty acid and inorganic aluminate class water-resisting agent etc., incorporation is about 2 ~ 3%.They mix in concrete water proof anti-seepage effect of mainly playing, do not have the effect such as pumping, expansion, apply comparatively powder water-resisting agent convenient.But current liquid repellent agent function ratio is more single, as being added with the admixture such as pumping agent or water reducer at Concrete Pumping Construction.And there are the needs that the water-resisting agent of single water-proof function and swelling agent can not meet development of the situation.Along with the development of Building Trade in China, Highrise buildings and underground civil defense engineering increase year by year.Because the maximization of engineering structure, complicated and concrete production and operating technique are increasingly to mechanize, modernization and commercialization development, more technical requirements is proposed for the rigidity water-proofing material mixed in concrete.
Summary of the invention
The object of the invention is the deficiency overcoming above-mentioned water-resisting agent, there is provided a kind of collect high-effective water-proof, diminishing, be pumped to one liquid repellent agent, significantly can increase mortar, concrete early strength, increase mobility, improve guarantor and mould ability, and the pumping construction technical requirements of large fluidised form water-proof concrete can be met
For achieving the above object, the present invention adopts following technical scheme:
A kind of multifunctional high-performance the reinforcement of concrete waterproofing agent of organosilicon, is characterized in that: it is made up of the component of following weight ratio: organosilicon 20 ~ 35%; Naphthalene sulfonic acidformaldehyde condensation product sodium salt 5 ~ 20%; Trolamine 0.9 ~ 1.6%; Sodium lignosulfonate or calcium lignin sulphonate 5 ~ 15%; Citric acid 0.5 ~ 1.5%; The water of Sulfothiorine 5% ~ 15% and surplus.
Further, described in multifunctional high-performance the reinforcement of concrete waterproofing agent of organosilicon of the present invention, organosilicon 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 acidformaldehyde condensation product sodium salt 7.5 ~ 13%; Trolamine 1.2 ~ 1.4%; Sodium lignosulfonate or calcium lignin sulphonate 8 ~ 12%; Citric acid 1.0 ~ 1.3%; The water of Sulfothiorine 7.5% ~ 10% and surplus.
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 colloids can be formed and binding substances is filled in concrete by synthesis and reaction at concrete, plug the capillary-size pore in concrete, reduce the thin rate in hole, improve concrete degree of compactness and impermeabilisation ability.
Naphthalene sulfonic acidformaldehyde condensation product sodium salt of the present invention is its fluidized composition, and it is a kind of surfactant, and its effect fully disperses cement, and the moisture release making cement roll into a ball parcel is come.Under the condition not increasing concrete water-cement ratio, the concrete slump can be increased significantly, thus ensure neither to affect the requirement that concrete intensity can meet again Concrete Pumping Construction.
Sodium lignosulfonate or calcium lignin sulphonate are its diminishing component.It can reduce concrete water cement ratio significantly, reduces porosity, increases concrete density thus greatly improve concrete intensity and impermeability.
Its slow setting of 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 the early stage and later strength of concrete and develop.
The drought of trolamine of the present invention strong and strengthening action structure adjusting mortar, concrete each age strength, meanwhile, be also improved effect of mortar, concrete density.
The high early strength function of Sulfothiorine of the present invention can solve the early low by force deficiency of former waterproofing agent of organosilicon.
The present invention, after compound, gives full play to effect of each component, realizes multifunction and the high-performance of water-resisting agent.
Concrete waterproofer of the present invention succeeds in the commerical ready-mixed concrete test of many times of underground works, can directly pumping without the need to pumping agent.Within 7 days, ultimate compression strength is not less than 150, and within 28 days, ultimate compression strength is not less than 135.Infiltration ratio is all lower than 30%.Ultimate compression strength loss ratio is not more than 50.Mass loss rate is not more than 70.All indexs of admixture all meet the technical requirements of JC474-1999 " mortar, coagulation foretell water-resisting agent " acceptable end product.
