Abstract
The present invention belongs to the technical field of building materials, particularly to a high performance cement-base water seal and leak stoppage material. The present invention is composed of portland cement, high alumina cement, 0.16 to 2.5mm of quartz sand, cellulose, water reducing agent, gypsum and quicklime powder. The present invention can mix mortar which is quickly condensed and hardened and can carry out the water seal and leak stoppage treatment for the water penetration positions of buildings(structure) such as roofs, wall surfaces, ground, large dams, tunnels, pools, etc. in high efficiency. Accordingly, leak is thoroughly treated and living environment is greatly improved. The service life of concrete structure(structure) is prolonged. The present invention is suitable for constructions such as reinforced concrete, light aggregate concrete, industrial and civil constructions, underground chambers, bridge beams, large dams, tunnels, etc.
Description
Technical field
The invention belongs to building material technical field, be specifically related to a kind of high-performance cement-based sealing patching materials.
Background technology
Current, owing to do not take into full account the impermeability of concrete material and the brittle cracking of concrete structure when design and construction, the seepage disease of various degrees such as many large-sized concrete buildingss, concrete diaphragm wall, vault, tunnel has had a strong impact on its functions of use.And the difficulty that these works are repaired is very big.Common way has following two kinds:
1) with admixture the sand-cement slurry of water reducer, water-resisting agent and/or micro-expanding agent etc. wipe one's face;
2) brushing polyurethane waterproofing coating, silicon rubber waterproof coating or organosilicon etc. on metope.
These two kinds of methods can improve the anti-leakage of concrete body to a certain extent, but, the seepage phenomenon often occur in delivered and the engineering that comes into operation in, at this moment because water pressure is bigger, use first method, because the cohesiveness of conventional cement mortar and basic unit is relatively poor and time of coagulation is longer, is usually just washed away by pressure water before its setting and harden is set up intensity; If adopt a kind of method in back, these waterproof paints all are solvent type on the one hand, can't combine with wet metope, and on the other hand, Bao coating is difficult to the effect of renitency water like this.So these two kinds of common practices all can not effectively solve the sealing leak stopping problem of the concrete structure that seepage takes place.
Summary of the invention
The object of the present invention is to provide a kind of high-performance cement-based sealing patching materials that can effectively carry out quick blocking to concrete structure (structures) penetrating passage.
The high-performance cement-based sealing patching materials that the present invention proposes, by ordinary Portland cement, high-alumina cement, 0.16-2.5mm quartz sand, Mierocrystalline cellulose, water reducer, gypsum, calcium lime powder are formed, and the weight ratio of each component is:
Ordinary Portland cement 100
High-alumina cement 20-35
0.16-2.5mm quartz sand 90-120
Mierocrystalline cellulose 0.02-0.08
Water reducer 0.5-0.9
Gypsum 2.0-3.5
Calcium lime powder 2.0-4.0
The preferable weight ratio of each component is:
Ordinary Portland cement 100
High-alumina cement 23-32
0.16-2.5mm quartz sand 95-112
Mierocrystalline cellulose 0.04-0.06
Water reducer 0.5-0.7
Gypsum 2.0-3.1
Calcium lime powder 2.0-3.1
Among the present invention, water reducer is the naphthalene sulfonic acidformaldehyde condensation product high efficiency water reducing agent, sulfamate high-effective water-reducing agent, melamine high-efficiency water-reducing agent, polycarboxylate high-efficiency water reducing agent a kind of.
Preparation method of the present invention is: by aforementioned each part by weight weighing each component, above raw material is mixed by physical mechanical, stir, promptly obtain this product.
Among the present invention, ordinary Portland cement is as inorganic coagulation material, can with mixing water generation hydration reaction, produce hydrated product, the sclerosis back produces intensity, and can be bonded together with base part, forms whole.Hydration and hardening speed was fast after water was met in the effect of high-alumina cement, made this product have ideal rapid coagulation Hardenability, was beneficial to set up intensity immediately after the percolating water place crammed.0.16-2.5mm the effect of quartz sand is the skeleton that serves as hardened cement paste, can gain in strength and reduces contraction.Mierocrystalline cellulose helps to improve the cohesive strength between this product and the leak stopping place substrate; The effect of water reducer is plasticizing water-reduction that mortar is played, thereby gains in strength.The effect of gypsum is to provide a certain amount of SO for the slurry system
4 2-, react with the hydrated product of high-alumina cement, form and have certain volume expansible ettringite, the volumetric shrinkage of compensation mortar.The effect of unslaked lime only is aquation early, not only emits certain heat, quickens the aquation of silicate cement and high-alumina cement, and the alkali environment of high density is provided for the formation of high-alumina cement participation ettringite.
The present invention is a grey dry powder material, and during use, suitable amount of water is the 10%-25% of dry powder material weight, and concrete amount of water is determined by test according to the required flowability that slurry is reached.
The present invention uses as the sealing patching materials, effective shutoff percolating water passage, have time of coagulation fast, and basic unit's cohesive strength height, shrinking percentage low, product original characteristic such as construct on being particularly suitable at the bottom of the wet basis.
Cohesive force at the bottom of the present invention and the wet basis is big, and time of coagulation is extremely short, the back pressure-proof and snap-resistent intensity height that condenses, and have very ideal compensate for shrinkage.
The present invention can be widely used in the sealing leak stopping of structures such as concrete structure, bridge, tunnel, vault, dam, pond, water tower to the effect of inside concrete reinforcing bar non-corroding.
