Description
Technical field
The invention belongs to the field of building materials, in particular to a kind of waterproofing and anti-leakage composite material for concrete.
Background technique
Concrete is one of the present age most important civil engineering material, is widely used in the every aspect of building field.But
It is that, due to concrete, especially mass concrete and high-strength concrete etc., generally existing shrinkage phenomenon leads to concrete cracking,
The reduced performances such as concrete strength, antiseepage, anticorrosive.And it is bright existing for expansive concrete material currently used in the market
Phenomena such as aobvious defect is: the heat of hydration of concrete is high, and concrete shrinkage deformation is big, generally existing concrete cracking, leakage, together
When, also greatly reduce concrete strength.And domestic various types of compensating shrinkage of concrete material, such as swelling agents
All it is to carry out high-temperature process using pure raw material Deng, the overwhelming majority, had not only caused huge energy consumption, but also give environment
Bring influences to some extent.Since production is at high cost, so, the market sale price of such product is expensive.
Though effect is unobvious in addition, external imported product has certain waterproofing and anti-leakage performance.Therefore, for
Concrete construction, especially for mass concrete, high-intensitive concrete construction (such as Hydropower Dam, military engineering, nuclear power
Stand, subway etc.), find it is a kind of can effectively prevent concrete cracking and leakage under the premise of proof strength, be always division of construction
The great research topic of skilled worker author.
For above-mentioned phenomenon, 104140219 B of patent CN discloses a kind of concrete waterproofing and anti-leakage agent, including as follows
The following component of parts by weight: 10-70 parts of flyash, 10-50 parts of fluorgypsum, 10-70 parts of phosphorus ore slag, the concrete is anti-with anticracking
Phenomena such as penetration enhancer can reduce the heat of hydration, and compensating concrete is shunk, and improves concrete strength, prevent its cracking, leakage, improves
The stability and durability of concrete；But there are still certain defects in use with waterproofing and anti-leakage agent for the concrete: 1.
The concrete waterproofing and anti-leakage agent does not have self-cleaning function；2, the concrete with waterproofing and anti-leakage agent to the frost resistance of concrete with
And corrosion resistance can meet the requirement of society, require further study and improve.
In addition, attention is more spent in and finds graphene etc. at present in the industry in terms of waterproofing and anti-leakage composite material
Nano material or other new materials substitute traditional concrete additive formula, although sometimes can be to a certain extent
Improve the performance of concrete additive, but cost of manufacture is too high, for the concrete for being widely used in civil engineering, fits
It is relatively narrow with range.
Therefore, a kind of anti-freezing property and corrosion resistance for having self-cleaning function and concrete capable of being effectively improved is researched and developed
The waterproofing and anti-leakage composite material for concrete of energy is necessary.
Summary of the invention
Have self-cleaning function the technical problem to be solved in the present invention is to provide a kind of and concrete can be effectively improved
The waterproofing and anti-leakage composite material for concrete of anti-freezing property and erosion-resisting characteristics.
In order to solve the above technical problems, the technical solution of the present invention is as follows: a kind of waterproofing and anti-leakage composite wood for concrete
Material, innovative point are: the following component including following parts by weight: 82-83 parts of calcium carbonate, 2-5 parts of magnesium carbonate, titanium dioxide
0.3-4 parts, 5-6 parts of gelatine powder, 0.2-0.3 parts of zinc oxide, 0.5-0.6 parts of plumbi nitras, 1-20 parts of stearic acid, brown eleostearic acid 0.5-
1.0 parts and polyethylene glycol 0.2-0.3 parts.
Further, it is 1-3 μm of precipitated calcium carbonate that the calcium carbonate, which selects partial size,.
Further, it is the oxide powder and zinc of 360-420 mesh that the zinc oxide, which selects granularity,.
The present invention has the advantages that
(1) present invention is used for the waterproofing and anti-leakage composite material of concrete, and using calcium carbonate and magnesium carbonate as major ingredient, plumbi nitras is
Reinforcing agent, and the proportion of calcium carbonate, magnesium carbonate and plumbi nitras is set as 82-83:2-5:0.5-0.6, can effectively it enhance mixed
Coagulate the mechanical property of soil, the i.e. compression strength of concrete, split tensile strength and anti-abrasion strength；Meanwhile parts by weight press 0.3-4:
The burden control titanium dioxide and zinc oxide of 0.2-0.3 prepares the brightening agent with good dispersion, can make to be attached to mixed
Organic pollutant on solidifying soil surface is degraded in time under the action of ultraviolet light and these degradation products can be fallen by rain drop erosion, makes
Concrete surface remains cleaning；In addition, with the gelatine powder of weight proportion 5-6:1-20:0.5-1.0:0.2-0.3, tristearin
Acid, brown eleostearic acid and polyethylene glycol prepare the reinforcing agent with good dispersion, and by reinforcing agent and major ingredient, brightening agent and enhancing
Agent can greatly improve the anti-freezing property of concrete, and can be effectively improved Sulfate Resistance of Concrete by synergistic effect
It can, wherein stearic acid can generate fluid-tight double salt in condensation hardening process, rise and promote structure densification, to improve
The anti-permeability performance of concrete；Importantly, the present invention overcomes the technology path prejudice of those skilled in the art, using conventional object
Matter simultaneously realizes superior technique index by reasonably matching.
(2) present invention is used for the waterproofing and anti-leakage composite material of concrete, wherein it is 1-3 μm light that calcium carbonate, which selects partial size,
Matter calcium carbonate, precipitated calcium carbonate fine particles, surface are rougher, large specific surface area, can increase substantially the closely knit of concrete
Degree is conducive to promote salvaging quality；Meanwhile the compactness for improving repairing concrete is important to preventing internal steel bar corrosion from having
Effect；Wherein, it is the oxide powder and zinc of 360-420 mesh that zinc oxide, which selects granularity, during the initial set of concrete, with water and acid,
Alkaline matter neutralizes, and gradually separates hydrogen and oxygen, makes gas, be discharged from concrete, while taking away the part heat of hydration, subtract
The generation of few temperature shrinkage fracture.
