The concrete sealing curing agent was invented by a German scientist in California after World War II. After decades of development, its formulation was gradually improved from sodium-based to lithium-based silicate raw materials. Now there is basically no real lithium-based water-soluble agent on the market, and it has been emulsified at high temperature with a unique catalyst to become a Chinese market. Three generations of products have been produced in the field: the strength of concrete mainly comes from the calcium silicate compound (C-S-H) produced by the silica and calcium in the cement component of concrete under the action of water, and C-S-H is the material that plays the main role in the strength of concrete. Concrete sealing hardener is a kind of colorless transparent liquid material. It is easy to use, non-toxic, non-flammable, strong permeability and permanent sealing concrete. It meets all VOC rules.

Sealing hardener
Mohs hardness Pinyin: m, SH, y, NGD, Mohs, Mohs: scale of hardness
Description: a standard for hardness of minerals. It was first put forward by Moss, a German mineralogical expert (Frederich Mohs) in 1824. A pyramidal diamond drill needle is used to scratch the surface of the minerals tested by scratching method. It is customary to use Mohs hardness in mineralogy or gemology. The measured scratch depth is divided into ten grades to indicate hardness: talc 1 (minimum hardness), gypsum 2, calcite 3, fluorite 4, apatite 5, feldspar; hose; periclase 6, quartz 7, Topaz 8, corundum 9, diamond 10. The hardness value is not the absolute hardness value, but the value expressed in the order of hardness.
Through effective infiltration (3-8mm), they react with concrete to produce hydrated calcium silicate, a chemical product with stable properties of non-expansion and non-contraction. This product fills the capillary holes in concrete and makes the whole concrete a solid solid solid body, thus obtaining a dust-free, compact whole and achieving hardening. Strong, anti-wear, dust-proof, waterproof, chemical erosion resistance, salt resistance, oil pollution resistance, safety and environmental protection sealing effect.
Advantage
1. prevent ASR (silicon adverse reaction). Concrete sealant curing agent has the characteristics of low viscosity and alkalinity. It reduces the reaction speed with calcium compounds in concrete, and can penetrate deeper, react more completely, and penetrate the concrete surface more evenly, so as to stop the adverse reactions of ASR.
3. does not contain expansive latex to prevent concrete from absorbing water and flooding.
4. effectively prevent water, oil penetration and chemical erosion.
5. to maximize the hardness, strength and wear resistance of concrete. Compared with untreated concrete, the hardness of concrete treated with concrete sealant and curing agent increases to 7 degrees Mohs. The strength of the ground treated with concrete sealant and curing agent is 50% higher than that of the untreated ground in one month, and increases continuously with time.
6. shine quickly and brighter.
7. good penetrability, permanent protection and no spalling.
8. waterborne products, excluding VOC, non combustible and non-toxic. It's a high-tech product.
9. construction is convenient, once coating, no need to scrub. Maintenance cost is low, no waxing.
10. for old and new concrete.
11., it is easier to clean.
Performance characteristics
Hardness: After treated with concrete permeable sealant and water-borne curing agent, the Mohs hardness will reach 9, and the Mohs hardness will increase by 45.3%.
Wear Resistance: The permeable waterborne solidifying agent of concrete can solidify various components of concrete into a hard entity to increase hardness and compactness. After the ground is ripened with the concrete sealing solidifying agent, the wear resistance will be increased to more than 8 times.
Dust-proof: The concrete permeable sealant water-borne curing agent reacts with the silicate in the concrete to form a chemical reaction on the concrete surface.
Form a dustless, dense whole, permanently controlling the concrete dust from the surface voids.
Skid resistance: the surface of ordinary concrete will precipitate from the surface and cause slippage. But the ground treated with concrete sealing and curing agent is different. It forms a solid and compact whole on the surface of concrete. Salt and alkali components will not precipitate from the surface.
Compressive strength: the compressive strength is increased by 27.3% compared with the untreated sample, and the flexural strength is increased by more than 3 times.
Anti-seepage: It can effectively infiltrate into concrete and react with it to lock the pore inside. It has permanent sealing effect on the surface of concrete and can effectively restrain water, oil and other surface dirt from entering concrete.
Weathering resistance: Ultraviolet radiation and water spraying have no adverse effects on the treated samples. They can effectively prevent the passage of chloride ions. Tests show that the treated ground will not be affected by exposure to electromagnetic or water mist.
Corrosion resistance: the treated ground will greatly improve the corrosion resistance of concrete.
Bright: The concrete floor treated with concrete sealing and curing agent will have marble-like luster, and the longer it is used.
The better the gloss.
Environmental Protection: Concrete Sealing and Curing Agent is a kind of concrete sealing, dust-proof, wear-resistant hardening agent, colorless, odorless, non-toxic.
Non combustible can make the concrete strong and dustproof; it can prevent water, oil seepage, alkalinity, weathering and so on.
Construction method
Clean the surface of base course, remove floating ash, oil pollution and other unfavorable substances; if there are too many pits in old base course, it needs to be repaired in advance; according to the construction area, the dosage of high permeability sealant and curing agent should be measured.
The high permeability sealant is evenly poured on the ground, flowing freely and penetrating. At the same time, the whole ground can be evenly penetrated by wipers. When the base surface penetration reaction becomes slippery and thick, the water mist wets the sticky surface to make the high permeability sealant continue to penetrate.
Observe the compactness and permeability of the base surface, and paint the surface three times or more with high permeability sealant and curing agent.
When the permeation reaction of the base surface is complete (the surface moisture is not completely dry is preferable), use a professional cleaning machine to clean the surface and remove excess materials.
After 24 hours of completion, the ground surface is polished with soft wool polishing pad, and the base surface is polished several times with resin abrasive. The longer it takes, the better the gloss.
Scope of application
Large factories, logistics warehouses, production workshops, supermarkets, exhibition centers, airports, underground garages, sports centers, hospitals, etc.
Reaction principle
Concrete sealing and curing agent is a kind of active colorless transparent chemical water-borne agent. It is composed of inorganic substances, chemical active substances and complexes with unique formula. It is easy to use, non-toxic and non-flammable. It can reduce the adsorbability of concrete surface, prevent dust and wear. Its working principle is to react with a large number of semi hydrated cement, free lime and calcium in concrete (continuous reaction time is about 60-90 days) to form a permanent gel, which can crystallize into hardened and wear-resistant structure inside the treated concrete. So as to get a clean and compact whole.
