Description
Technical field
The invention belongs to concrete additive technical fields, and in particular to a kind of conjunction of autogenous healing, which subtracts, seeps additive, system
Preparation Method and its application method.
Background technique
Normal concrete refers to using cement as major gelled material, and water, sand, stone, mix when necessary chemical admixture and
Mineral admixture is cooperated by proper proportion, by artificial stone made of uniform stirring, closely knit molding and maintenance hardening.Coagulation
Native stone material is most widely used construction material in the world, but physical property due to its own constitutive material and manufacture craft,
The reasons such as construction environment are easy to appear crackle or phenomenon of rupture under the action of exposing to the weather, expanding with heat and contract with cold.To improve coagulation
The mechanical property and weather resistance of soil structure, the present invention develop a kind of new concrete self-healing and subtract infiltration additive, activity
Substance can be chemically reacted with aquation substances a variety of in concrete material under the action of water, generate insoluble crystalline solid, envelope
The micro-cracks generated on stifled concrete structure, in concrete dry and wet cyclic process, continuous action.
Summary of the invention
In view of the deficiencies of the prior art, the purpose of the present invention is to provide a kind of conjunctions of autogenous healing to subtract infiltration addition
Agent, preparation method and its application method.
Technical solution of the present invention is summarized as follows:
A kind of conjunction of autogenous healing subtracts infiltration additive, including following parts by weight of component: 14-15 parts of superfine silicon dioxide, five
38-39 parts of water sodium metasilicate, 35-40 parts of calcium oxide, 7-10 parts of calcium sulfate, 9-13 parts of magnesium sulfate, 8.5-10 parts of zinc sulfate, clothing health
Sour sodium 5-8 parts, 0.5-1 parts of hydroxypropyl methyl cellulose, 0.2-0.5 parts of polycarboxylate water-reducer.
A kind of autogenous healing conjunction subtracts the preparation method of infiltration additive: each raw material being uniformly mixed, 60 DEG C of low temperature dryings
30min, hermetically storing.
A kind of autogenous healing closes the application method for subtracting and seeping additive: in use, the self-healing is subtracted seep additive by
It is added in cementitious material according to the quality of 0.8% concrete gel material, is uniformly mixed.
Beneficial effects of the present invention:
1) present invention is with superfine silicon dioxide, metasilicate pentahydrate sodium, calcium oxide, calcium sulfate, magnesium sulfate, zinc sulfate, clothing health
Sour sodium is additive active constituent, under the action of water, it is anti-chemistry can not only to occur with aquation substances a variety of in concrete material
It answers, meanwhile, complicated chemical change can also occur between each other for each active material, and then generate insoluble complicated and confused shape crystalline solid,
The micro-cracks generated in blocking concrete structure, in concrete dry and wet cyclic process, continuous action.
2) present invention subtract seep additive application self-healing effect in commerical ready-mixed concrete it is obvious, significantly improve concrete impervious
Grade extends concrete set time, reduces concrete water bleeding rate, improves concrete crushing strength, General Promotion coagulation soil property
Amount.
