The invention relates to a permeable crystallization waterproof agent. The agent is prepared by mixing the following components in percentage by mass: 35 to 65 percent of superfine mineral powder, 15 to 30 percent of fly ash, 8 to 20 percent of calcium hydroxide, 1 to 3 percent of nano silicon oxide, 5 to 14 percent of organic silicon aid, 0 to 2.4 percent of sodium polyacrylate and 0.1 to 1.5 percent of polycarboxylic acid water reducing agent. The permeable crystallization waterproof agent is doped into concrete, active substances contained in the agent can react with a cement hydration product in the concrete to generate an insoluble crystal, and the capillary pore channels and micro cracks of the concrete are blocked, so that the density of the concrete is improved, and the permeability resistance and durability of the concrete are improved; and the agent can be widely applied to the permeability-resistant and waterproof construction of subways, ports, docks, dams, ponds, tunnels, basements and the like.
Description
Technical field
The invention belongs to building material technical field, relate to a kind of compsn, particularly a kind ofly be used for the capillary crystalline waterproofing agent that concrete water-proofs such as subway, port and pier, Ba Chi, tunnel, vault are used.
Background technology
Concrete is a kind of heterogeneous body porous hard brittle material, sees from microtexture to belong to vesicular structure, and its inside exists a large amount of holes and tiny crack, and these microdefects all will become concrete penetrating passage of later stage.In addition, the thermal cracking that concrete shrinkage crack that the surface-moisture evaporation produces when the plastic stage and sclerosis stage produce also can increase concrete perviousness, has had a strong impact on concrete weather resistance.
The anti-permeability performance that improves concrete structures is the key factor that improves concrete durability and other performances; There are several kinds of important means that improve the concrete safety in domestic for this reason priority, like impervious, cement, expansive concrete, flexible waterproof material, inorganic anti penetration enhancer or the like.More than concrete impervious technology and material relative merits are separately all arranged, possess the advantage early strong, high-strength, that time of coagulation is short, contract with dry rate is low, impervious like the impervious, cement concrete, but more difficult transportation and storage, and cost is higher; Expansive concrete is to add swelling agent in the concrete, can offset because the tensile stress that drying shrinkage produces avoids concrete to produce the crack, but expansive concrete requires the concrete pouring time long, and influence factor is a lot of instability etc. in the actual application.Flexible waterproof material can closed concrete the surface, stop the infiltration of water, but have non-refractory, be prone to shortcomings such as aging, that the life-span is short.The inorganic anti penetration enhancer is through mixing silicate, molysite or inorganic villaumite; With hydrated product in the cement generation colloidalmaterial that reacts; Stop up the inside concrete hole; Thereby improve its density, but former this product not only function singleness, seepage control and crack resistance weak effect, and be incorporated into the long-term behaviour that influences its workability and later stage in the concrete.
Cementitious capillary crystalline waterproofing agent is because anti-permeability performance is good; Has stronger self-repair function; Therefore in a lot of fields particularly waterproofing work such as underground waterproof engineering and covil construction have irreplaceable meliority, it has solved the conventional waterproof agent and has caused concrete newly to mix the problem of poor performance, and inner active ingredient of after stage and the hydrated cementitious product insoluble crystal of generation that reacts; Stop up the inside concrete tiny crack; Make concrete more closely knit, reach the purpose of concrete water-proof, satisfy building and structures durability requirement.At present, permeable crystalline waterproofing material mainly adopts external intellecture property product, like U.S. PENETRON, Canadian XYPEX etc.; Domestic product is generally the finished product of reprocessing formation from external import penetration crystallization masterbatch; Like Chinese patent number is CN101654351A, CN101362867A etc., and it mainly adopts the penetrant crystalline masterbatch to be configured, and does not have to form own real intellecture property; Therefore price is relatively costly, thereby has hindered its application in waterproofing work.
Summary of the invention
The object of the present invention is to provide a kind of capillary crystalline waterproofing agent, after concrete adds this water-resisting agent, not only can pumping construction, and possess anti-carbonization, anti-hazardous medium infiltration function, the great raising that also obtains of concrete weather resistance simultaneously.
The applicant finds after deliberation: the major cause of concrete structure deterioration is the intrusion of water; Also comprise simultaneously the objectionable impurities that is dissolved in the water; Thereby cause that concrete produces tiny crack; Causing inside concrete damage, especially cl ions or carbonic acid gas is that carrier is invaded inside concrete with water, can cause inner reinforcing bar generation corrosion and concrete generation carbonization.
Based on above-mentioned research, the present invention is the basis to mix thinking in the cementitious capillary crystalline waterproofing agent, is filler with super finely ground slag and flyash; Improving the inside concrete microstructure, is active ingredient with the nano silicon, and selects proper auxiliary agent; In pore,, generate water-fast complicated and confused shape xln, sealing inside concrete pore and microfracture with hydrated cementitious product generation physical-chemical reaction; Thereby the effectively shutoff intrusion of water that comes from the outside, play block water, waterproof effect.
Concrete technical scheme of the present invention is following:

Organosilicon auxiliary agent 8% ~ 14%
ZX-I 1% ~ 2%
Polycarboxylate water-reducer 1.0% ~ 1.5%
Above-mentioned super finely ground slag is a white, specific surface area>=8000cm
2/ g;
The fineness of above-mentioned flyash is 45 μ m, square hole sieve screen over-size＜10%;
The median size of above-mentioned nano silicon is tens nanometers;
Above-mentioned organosilicon auxiliary agent is a pulverulent solids, and the organosilicon auxiliary agent of all kinds all is applicable to the present invention, preferred silane class organosilicon or type siloxane organosilicon;
Above-mentioned polycarboxylate water-reducer is a pulverulent solids, and the polycarboxylate water-reducer of all kinds all is applicable to the present invention, preferred, polyethers class water reducer or polyester water reducer.
Capillary crystalline waterproofing agent of the present invention in use; It is the water-proof concrete that this agent (equivalent replacement cement) of 2% ~ 4% of in concrete, mixing gelling material weight can obtain not influence workability of concrete; In mixing the concrete of capillary crystalline waterproofing agent; Through the filling effect and the secondary hydration effect of super finely ground slag, flyash, can improve the inside concrete microstructure, play certain early strength function simultaneously; Can generate insoluble crystalline product with hydrated cementitious product reaction in the inside concrete hole through nano silicon, stop up the concrete capillary-size pore, play closely knit waterproof effect; And organosilicon auxiliary agent and ZX-I etc. play the booster action of water proof anti-seepage, and the while is as the complexing auxiliary agent of active ingredient silicon-dioxide; Through polycarboxylate water-reducer, can improve concrete workability and lower concrete folk prescription water consumption further increases concrete density.
