Description
Technical field
The present invention relates to a kind of cementitious capillary waterproofing material, is a kind of novel cementitious capillary waterproofing material.
Background technology
GB " GB18445 (2001) cementitious capillary waterproofing material " has promoted the researchdevelopment and the practical applications of this material since implementing on March 1st, 2002, improved the working efficiency of waterproofing work, has reduced the comprehensive cost of waterproofing work; In a way, satisfied modern building to durability requirement.We can say that cementitious capillary waterproofing material wins each side personage's favor with its comprehensive advantage, in rigidity water-proofing material, leak stopping sealing material series, established own consequence.
The research and the practical applications of external cement group water-proofing material, the course of the last 100 years of having passed by.The research and development in this field, successively the type of developing and practical applications mainly contains following 3 kinds: (1) cement based MOX water-proof material; (2) cementitious capillary waterproofing material; (3) polymer modified cement base waterproof material.
Cementitious capillary waterproofing material is nineteen forty-two Germanization scholar Lauritz Jensen (Lao Lunsijiexun) in the practice that solves plastered ship percolating water, the innovation and creation of generation.The America and Europe is called: Czpillary/Crystalline Waterproofing Materials is called for short CCCW.This material system is made up of ordinary Portland cement, silica sand or silica sand, the chemical complex that has an activity functional groups, and it is with powder-form supply user use.The most application of this material be only with water mix (also will add chemicaladditives under the situation about having), be deployed into the slurry that can brush or spray.As its intension of title signal; It not only forms an effective water-proof coating; And the activity chemistry mixture that originally contains, to the inside concrete infiltration, with moisture, Ca (OH) the 2 generation chemical reactions in the concrete; Form insoluble xln mixture, and then lean on xln to increase the filling capillary channel.These xln can rise to 0.4mm-promptly be higher than the overall dimension of concrete capillary caliber usually, and concrete is fine and close, waterproof thereby make.
The common feature of cement group water-proofing material is: can be used for new, old concrete basal plane; Can on moist basal plane, construct; Newly-built and recovery project all can adopt.Cementitious capillary waterproofing material is compared with other two types, possesses the advantage that can be used for water works, and this point is that generally acknowledge countries in the world.
Cementitious capillary waterproofing material forms series product from the German VANDEX brand in early stage (the 1940's) the dozens of brands such as developing Canadian XYPEX, Canadian PERMQUIK, Canadian KRYSTOL, Singapore FORMDEX, U.S. PENETRON, French DIPSEC, Australian CRYSTAL, Japanese PANDEX of extending.The cement-base infiltration crystallization type material is to advocate the outside surface waterproof that is used for full underground concrete structure in the process that development engineering is used at first.Afterwards, found that it had its special-effect at back side (structure internal surface waterproof).Particularly the application of similar engineering such as sewage work and ground domestic water retention basin is rather desirable.Since the sixties, cementitious capillary waterproofing material progressively enlarges kind as a kind of effective ways of concrete structure back side WATER REPELLENT (inner waterproofing method), constantly gets into the frontier that building operation is used.
Dragons and fishes jumbled together in present water-proof material market, and especially the cement-based penetrant water-proof material is uneven especially, can't guarantee waterproof effect, causes the complaint of a large number of users.So press for a kind of novel concrete base osmotic crystalline waterproof material at present, solve the difficult problem of waterproof industry, bring good economic benefit and social benefit.
Summary of the invention
The objective of the invention is to solve a difficult problem and the bad problem of existing waterproof paint performance thereof that seepage perplexs people for a long time; Water-proof material of the present invention has better cohesiveness, water-repellancy and ventilation property; Can overcome the shortcoming of cementitious capillary waterproofing material in the prior art; Be fit to large-scale promotion application, have remarkable economic efficiency and social benefit.
The technical solution adopted for the present invention to solve the technical problems is: a kind of cementitious capillary waterproofing material, to form by silicate cement, silica sand, silicon powder, hydrophober and Mierocrystalline cellulose, and each material ratio by mass percentage is following:
Silicate cement: 1
Silica sand: 0.6～0.7
Silicon powder: 0.08～0.1
Hydrophober: 0.002～0.003
Mierocrystalline cellulose: 0.005～0.1.
As the further design to the aforementioned techniques scheme: aforesaid silicate cement is common silicate cement, and staple is a tricalcium silicate; The particle diameter of described silica sand is 100～200 orders; The particle diameter of described silicon powder is 800～1200 orders; Described Mierocrystalline cellulose is a methyl cellulose ether.
The ordinary Portland cement that uses among the present invention, staple is by tricalcium silicate (C
3S) etc. mineral substance is formed, and after silicate cement was met water, hydration reaction can take place the various mineralogical compositions in the cement very soon, generates various hydrates and forms comparatively fine and close sand-cement slurry sclerotium with aggregate such as silica sand.
In sum, the advantage of cementitious capillary waterproofing material of the present invention is following:
(1) superpower water-repellancy and impermeability, and have self-healing ability can be resisted secondary or seepage repeatedly;
(2) porous also forms fluid-tight complicated and confused shape xln with it to ground inside;
(3) with the same life-span of concrete structure, permanent waterproof;
(4) resist high hydrostaticpressure, have the water-proof function of the negative water surface;
(5) can on the moist basal plane of no ponding, construct;
(6) wear resistance is good, and cohesiveness is good, can directly on waterproof layer, plaster behind dried the consolidating, and smooths and use suitable glue for tile to paste various clay facing tiles;
(7) environmentally friendly machine: nontoxic, harmless, can directly be used for pond and fishpond;
(8) can prevent that moisture, salinity from polluting bacteria growing inhibiting;
(9) has air permeability and good;
(10) simple to operate, only need on-the-spot stirring to use.
