Summary of the invention
The invention aims to overcome the deficiencies of the prior art and provide a kind of cementitious capillary waterproofing material,
The Matter Composition that it is formed is simple, and several Matter Composition prices are low, so the waterproof material low manufacture cost of composition, is easy to push away
Extensively；In addition, waterproof performance is greatly improved；In addition, either composition is formed, is used for, national green can be met
The related request of environment-friendly building materials product.
Above-mentioned goal of the invention is achieved through the following technical solutions, a kind of cementitious capillary waterproofing material,
It is characterized by: the waterproof material is mixed by the component of following weight proportion: 56~62 parts of cement, 27 parts of quartz sand~
33 parts, 7~11 parts of complex catalyst, 1~3 part of zeolite waterproofing agent；The complex catalyst by following weight proportion component
It is mixed and modified to form: 87~75 parts of zeolite powder, 5~10 parts of lithium metasilicate, 5~10 parts of gluconate, isobutyl triethoxy silane
3~5 parts.
Preferably, the zeolite waterproofing agent is modified zeolite, fatty acid, the surface-modified processing of silane Composite Milk again
Rubber powder, cellulose ether form.
Preferably, the gluconate be one of calcium gluconate, sodium gluconate, magnesium gluconate or
Two kinds or more.
Beneficial effects of the present invention are as follows: because this waterproof material only uses cement, quartz sand, complex catalyst, zeolite anti-
Four kinds of Matter Compositions of aqua, and four kinds of Matter Composition prices are all very limited, so low manufacture cost, is easy to promote；And four kinds of objects
Zeolite waterproofing agent in matter composition utilizes its distinctive adsorptivity, ion exchange using high grade natural zeolite as primary raw material
Property, acid resistance, alkali resistance, by the way that activation, roasting, surface be modified etc., series of process are handled, and are that collection is closely knit, bleed, are hated
The water-proofing anticrackings such as water, secondary crystallization, microdilatancy, decrement mechanism is in the multifunctional mortar of one.Its water-proof mechanism: modified processing
Zeolite crystallite afterwards can improve the uniformity of cement mixture, workability, promote hydrated cementitious and form hydrophobic adsorption layer and not
Dissolubility colloidal substance, filling concrete capillary slit prevent water translocation, reduce water absorption, improve hydrophobicity and impermeability.Due to
Zeolite is rich in SiO2, activity A12O3And various trace elements, the hydration reaction of continuous uniform can be carried out with cement, generation has
Calcium sulphoaluminate, that is, entringite of micro-expansibility can play the role of compensation and shrink；Due to the zeolite through silane surface modified processing,
It can significantly reduce the surface tension of Behavior of Hardened Cement Paste, reduce the negative pressure generated after the dehydration of cement pore, to reduce the dry of Behavior of Hardened Cement Paste
Contracting.Activated silica and activated aluminum in zeolite can participate in cementitious material hydration and hardening, generate hydrated calcium silicate and calcium aluminate, increase
Gelled product improves cementing with cementitious material, increase density of gathering materials, raising compression strength.It simultaneously can also be with hydrated cementitious
Secondary response occurs for the calcium hydroxide and gypsum generated afterwards, generates hydrophobicity crystalline material blocking pore, seam, further increases
Density and crack self-healing.The special porous rack-like structure of zeolite and pozzolanic activity, moreover it is possible to reduce hydration heat of cement and
Inhibit alkali-aggregate reaction, makes waterproof effect that there are long-time stability.Cementitious capillary waterproofing material of the invention is adopted
With complexing-precipitation reaction mechanism, there is the chemical activities that can be complexed with calcium ion in cementitious capillary waterproofing material
Substance-complex catalyst, under the collective effect of concentration and pressure difference, complex catalyst penetrates into concrete by carrier of water
Portion is complexed when by calcium hydroxide high concentration region with the calcium ion ionized out in concrete, is formed soluble easily in water unstable
Calcium complex.Complex compound is spread in concrete pore with water, encounters the higher unhydrated cement of activity, cement gel body
Deng, active chemistry will be replaced by more stable silicate, aluminate etc., occur crystallization, precipitation reaction, thus by hydrogen-oxygen
Change calcium and be converted into the crystalline compounds with some strength, is filled in crack and capillary porosity in concrete.And activity chemistry
Substance then becomes free radical again, and continuation is internally migrated with water.When concrete is in drying regime, it is situated between due to lacking diffusion
Matter, active material is in " suspend mode " state, and when there is water infiltration, active material will be activated once again, and new crystallization occurs for catalysis
Reaction, makes structurally waterproof.Therefore, such material has permanent waterproof characteristic.
