What is concrete sealing curing agent?
Concrete sealing curing agent is a kind of hard material produced by a series of complex chemical reactions between the compound penetrated into the concrete and the semi hydrated cement, free calcium, silicon oxide and other substances contained in the set concrete. These compounds will eventually improve the compactness of the concrete surface, thus improving the strength, hardness, wear resistance Impermeability and other indicators.

Causes and solutions of abrasion resistant floor blooming
The color of the floor is inconsistent and white in many places. The main reasons are as follows: 1. Aggregate itself: the quality of the toner in the raw materials is poor and the color is uneven.
2. The amount of aggregate is small, the aggregate layer is too thin to cover the cement layer below, and the cement slurry overflows.?
3. When pouring concrete, there is too much water, no bleeding during construction, too much cement slurry, and the aggregate has been dyed.
Use floor penetrant,? It is characterized by wear resistance, penetration, hardening, sealing, brightness, etc? It is a unique effect that other materials (such as epoxy, ordinary penetrant and paint) cannot achieve
Litec floor penetrant has good adhesion, penetration, fast drying, strong wear resistance, and is an oily liquid material with certain acid resistance, alkali resistance, color change resistance, water resistance, and impact resistance. Through effective penetration, the product can contact with the concrete floor to react chemically, forming a whole floor, and blocking the loose pores of the floor to get a dust-free and compact whole, So as to improve the abrasion resistance, compression resistance, compactness and impermeability of the floor. Undercutting solution? It solves the difficult problems of poor wear-resistant floor, sand and dust on cement floor, and can better meet your needs to form a uniform floor color and achieve the ideal floor application range of sealing and penetration;
Application of 25 concrete sealing curing agent in floor
The liquid sealing curing agent of Litec concrete has the advantages of hardening, abrasion resistance, sealing, dust-proof, impermeable, anti fouling, anti-skid, bright, curing, bonding * * *, and the unique high gloss formula, so that the newly treated floor can show a bright effect within 24 to 72 hours and achieve the functions of sealing, anti fouling, anti-seepage, and ensuring long-term wear resistance. The concrete sealing curing agent is odorless, harmless and incombustible, and meets the environmental protection requirements for volatile agricultural production system compounds (VOC)
Its main components are silicates. Working principle Diheng concrete liquid sealing curing agent will deeply penetrate into the concrete surface, and the free calcium hydroxide (Ca2 OH -) produces chemical reaction, compacts and hardens the concrete surface, so as to achieve the effect of blocking the capillary pores in the concrete, so that liquid water cannot pass through, but the water vapor can be distributed outside the surface, reducing the harm caused by surface stratification or foaming, and also preventing the generation of dust and the erosion of oil stains. Water, oil and other dirt penetrate into the surface below the concrete or gypsum body through the micro pores of the concrete or gypsum body to effectively seal the concrete or gypsum body for a long time, that is, to make the concrete or gypsum body become a solid and compact entity through chemical reaction.
The concrete sealing and curing agent is applicable to any new and old flat concrete surface that requires hardness, high abrasion resistance and high impermeability indoors and outdoors, such as roads, factories, shopping centers, warehouses, parking lots, service stations, aircraft hangars, freight distribution yards and other areas.

1 Why is the ground sanding and how to deal with it
Why is there sand and ash on the ground? Reasons for sand and ash on the ground:
1 Improper use time
The engineering practice has fully proved that when the cement concrete floor has not reached more than 70% of the design strength, the construction of the next process will be carried out on it, so that the ground surface will be subject to frequent vibration and friction, which will easily lead to ground sanding. This is especially true when the temperature is low.
2 Water cement ratio is too large
? Scientific experiments have proved that the amount of water required for hydration reaction of commonly used cement is about 25% of the cement mass, that is, the water cement ratio of cement mortar is about 0.25. Such a small water cement ratio can meet the water consumption of hydration reaction, but it is very difficult in construction. In order to ensure the fluidity of construction, the water cement ratio is usually within the range of 0.40-0.60. However, the water cement ratio is inversely proportional to the strength of the cement concrete floor. If the water consumption is too large, it will not only greatly reduce the strength of the cement concrete floor surface, but also cause mortar bleeding, further reducing the strength of the cement concrete floor surface, which will lead to the problem of ash and sand on the cement concrete floor.
3 Improper construction process
Because the basic principle of cement setting and hardening is not understood, the calendering process of cement concrete floor is not properly arranged, and the bottom layer is too dry or wet, the calendering time of cement concrete floor is too early or too late. Engineering practice shows that if the calendering is too early, the cement hydration reaction has just begun, the gel has not yet been fully formed, and there is more free water in the mortar, although the calendering is carried out, there will still be a layer of water on the surface, which will seriously reduce the strength and abrasion resistance of the cement concrete floor; If the calendering is too late and the cement has finally set, not only the pores and trowel marks on the surface cannot be eliminated, but also the hardened surface will be disturbed, which will greatly reduce the strength and abrasion resistance of the cement concrete floor.
4 Improper maintenance
The cement enters the hardening stage after initial setting and final setting, which is the stage when the cement hydration reaction is intense. Under appropriate temperature and humidity conditions, with the deepening of hydration reaction, the strength of cement concrete ground is continuously improved. After the completion of the cement concrete floor, if it is not cured or not properly cured, it will inevitably affect the hardening speed of the cement concrete floor. If the curing temperature or humidity is too low, the hydration reaction of cement will slow down, and even stop hardening in serious cases, which will dehydrate the cement concrete and affect the strength. If the cement concrete ground is cured by watering before reaching the final setting, the surface will also have quality problems such as peeling, ash and sand.
5. Cement concrete is frozen
The cement concrete floor is constructed under low temperature in winter. If no insulation or heating measures are taken, the mortar is liable to be frozen. After being frozen, the volume of cement concrete will expand by about 9%, resulting in large ice expansion stress, and its strength will be greatly reduced; After thawing, the volume of cement concrete no longer shrinks, which increases the porosity of surface cement concrete; The adhesive force of the cement slurry film around the aggregate is destroyed, forming loose particles, and sand will also appear after friction.
6 Nonconforming raw materials
? The raw materials are mainly cement and sand. If the strength grade of cement used is too low, or there are expired agglomerated cement and damp agglomerated cement in the cement, the strength and wear resistance of cement concrete will be seriously affected. If the sand particle size is too small, its surface area will be large, the mixing water demand will be large, the water cement ratio will be increased, and the concrete strength will be reduced; If there is too much mud in the sand, it is bound to affect the bonding of cement and sand, and it is also easy to cause ground sanding.
7 Improper construction environment
During winter construction, temperature rise measures should be taken in the room where the cement concrete floor is newly poured. If the correct smoke emission measures are not taken, the carbon dioxide gas generated by combustion is in the lower layer of the air. After it contacts the surface of the cement concrete, it reacts with the calcium hydroxide generated by cement hydration and not yet hardened to generate white powdered calcium carbonate, It not only has low strength, but also hinders the normal cement hydration reaction, thus significantly reducing the strength of the cement concrete ground surface.
Treatment method for sanding and dusting of cement floor:
Litec concrete sealing curing agent is a kind of advanced chemical product in powder form. Its working principle is that after the curing agent penetrates into the concrete floor, it reacts with a large amount of semi hydrated cement, free calcium lime and other soluble particles in the concrete to form a long-term solidified solid. High density and high hardness cubic tetrahedral molecular structure mineral crystals can be formed inside and on the surface of the treated concrete, filling the voids, making the concrete structure more stable, thus enhancing the strength of the concrete itself. It can prevent damage caused by various chemical substances and completely prevent dust generation. Through one-time construction, it will coexist with the concrete, effectively improve the degree, density and wear resistance, and extend the original design service life for more than 20 years.
