Abstract
The component of water-proofing agent composition comprises (wt%) 20-60% of CaO/SiO2/Al2O3 composite breeze, 5-10% of naphthalene sulfonic acid formaldehyde condensate sodium salt, 15-50% of zeolite powder and 20-50% of active silica powder. Said water-proofing agent can be mixed with cement mortar to raise the water-resisting and water penetration resisting properties of cement mortar member and concrete building.
Description
The invention belongs to sand-cement slurry and concrete additive, particularly waterproof type additive.
Water-proof material can be divided into flexible waterproof material, rigidity water-proofing material and tile water-proof material by its attribute and form.
Its base-material of flexible waterproof material is organic or the organic/inorganic mixing material, this material has better elasticity or viscous deformation performance, but its subject matter is easily aging, work-ing life is short, all lost efficacy gradually about general ten years, and its use has limitation, and occasion all can't be suitable in that external wall, interior wall, vault back side, pond, ground be impervious etc.
Rigidity water-proofing material is made by inorganic materials, mainly contains water-proof concrete (concrete), waterproof mortar and improve the impervious ability of rigidity water-proofing material impervious agent, scrape paint etc.This material just grew up in recent years, although existing many kinds, what have also uses in some Important Project, and the problems and shortcomings that exist are very outstanding.At first hard and crisp because of its matter, it is poor to adapt to deformability, and cracking causes percolating water easily, and on exterior wall, the big area be full of cracks is very easily made in improper use, thereby loses waterproof effect especially; Next is that its impervious ability of present existing rigidity water-proofing material is mostly all at P
6～P
10About, there is the engineering of high impervious requirement to satisfy to multi-storey basement, subway, tunnel etc.; The 3rd is that existing rigidity water-proofing material site operation adaptive faculty is poor, and technology is numerous and diverse, the extremely difficult operation of general workman, and cost an arm and a leg, can't big area promote the use of.
The objective of the invention is to solve sand-cement slurry and concrete member seepage problem, a kind of high-effect cement mortar water-proofing agent is provided, the sand-cement slurry and the concrete member that are mixed with this water-resisting agent have high water repelling property.
The special character of its technical solution of trace-silicon high-effect cement mortar water-proofing agent of the present invention is the material that contains following weight percent in this waterproofing agent composite gross weight: CaO/SiO

This trace-silicon high-effect cement mortar water-proofing agent is a kind of inorganic powdered material, it contains multiple high-activity compound, mix in cement, in cement hydration process, can be formed with autohension and close-burning high-strength microcrystal, and excessive moisture can be absorbed, micro-cracks and capillary channel in sealing mortar or the concrete member, cement stone and aggregate are combined securely, and become the part of mortar and concrete, in the natural curing process, it can discharge the water molecules that is absorbed slowly, makes it continue hydration, form highdensity slaked lime, thereby reduce the pore volume, increase the glue boring ratio of cement stone, make the intensity and the impermeability of mortar and concrete, splitting resistance is further strengthened.Test shows, is mixed with the sand-cement slurry test block of this water-resisting agent, and its anti-penetration grade P＞24 are far above existing rigidity water-proofing material anti-permeability performance.For example: 1, adopt standard sand, 525
#Ordinary Portland cement, mix a kind of water-resisting agent 10% of the present invention (is benchmark with the cement weight), water cement ratio (water is than cement) is 0.6, and cement-sand ratio (cement is than sand) is 1: 2.5, and test block takes gravitational grouting to go into mold forming, wet curing seasoning after 7 days, impervious applied voltage test at hydraulic pressure 2.9MPa, was kept 60 minutes, waterproof, 7 days anti-penetration grade P＞28 of real examination.2, adopt standard sand, 525
#Ordinary Portland cement mixes a kind of water-resisting agent 10% of the present invention, and water cement ratio is 0.55, and cement-sand ratio is 1: 3, test block takes gravitational grouting to go into mold forming, wet curing seasoning after 7 days, and impervious applied voltage test is at hydraulic pressure 2.5MPa, keep 60 minutes, waterproof, 7 days anti-penetration grade P＞24 of real examination.3, adopt standard sand, the 525# ordinary Portland cement mixes a kind of water-resisting agent 10% of the present invention, and water cement ratio is 0.50, cement-sand ratio is 1: 2.5, test block takes gravitational grouting to go into mold forming, wet curing seasoning after 28 days, impervious applied voltage test, at hydraulic pressure 3.2MPa, keep 60 minutes, waterproof, 28 days anti-penetration grade P＞31 of real examination.
