What is a concrete floor hardener ? The concrete floor hardener is made of hardened ground material, commonly known as corundum flooring, and it is directly applied to the surface of the concrete that will be in the initial setting stage. Ground hardener has been rapidly popularized in Europe and the United States since the advent of the 1970s, becoming the perfect replacement for terrazzo floors. In the late 1980s, wear-resistant flooring was the first choice for developed countries. If you have such needs, you may wish to follow me to learn more about the relevant knowledge of concrete floor hardener ! Concrete floor hardener 1. Classification First, powdered cement-based solid surface hardener: also known as wear-resistant ground (Ping), corundum ground (Ping), cement-based aggregate wear-resistant ground (Ping). It is the best alternative to terrazzo floors. 1. Concrete floor hardener material composition: It is a kind of cement-based powder material pre-mixed in the factory. The main components are high-grade cement, wear-resistant aggregate (quartz sand, corundum, alloy aggregate, etc.), pigment powder (gray , red, green, blue, yellow), concrete additives (water reducer, etc.). 2, construction process: pouring primary concrete, flattening, picking pulp, remove excess bleeding - spreading concrete floor hardener - trowel compaction, trowel - smear curing agent - cutting expansion joints. 3. Advantages: The construction speed is fast (basic and grass-roots concrete floor is completed at the same time), the environment pollution is small during construction; the cost is low, and the abrasion resistance, hardness and impact resistance are good; the surface smoothness is good and can be colored. In general, this solid hardener floor is an economical and practical industrial floor. 4. Disadvantages: Relative to the epoxy floor, the appearance is slightly poor, color concrete hardener on the ground there will be more obvious color difference; concrete ground hardener forming the ground is still a concrete floor, although its density is significantly better than the degree of hardness Ordinary concrete floor, but its interior is still a microporous structure, its impermeability (especially the resistance to oil seepage), anti-fouling performance, easy to clean performance is far less than the epoxy floor. Therefore, concrete floor hardeners are not recommended for use where high ground cleanliness is required, or where there is often dripping of oil. 5. It is generally recommended to use concrete floor hardeners for applications where the degree of cleanliness or aesthetics is not high, and the emphasis is on economical, practical and durable applications. Second, liquid concrete floor hardener: also known as cement floor sand treatment agent, concrete seal curing agent, liquid surface hardening agent, concrete surface enhancer, concrete penetration hardening agent. This is a water-soluble chemical hardener that generates a large amount of gel by undergoing a series of chemical reactions with the cement hydration by-products. This gel can block the pores inside the concrete, so it can adjust the density of the concrete floor. Hardness and so on. The chemical reaction of some two-component liquid surface hardeners is more complex, not only generates gels, but also generates some stable silicon-silicon-based hardeners, thereby greatly improving the surface hardness, strength and compactness of cement concrete floors. 1. Main material composition: Reactive alkali metal silicate, modified active silicate, surfactant, catalyst, etc. Some liquid surface hardeners also contain fluorosilicates. 2, can not be mixed with concrete or cement mortar, can only use the existing cement or concrete floor. By infiltrating into the concrete ground, it does not change the original appearance of the ground. 3. Advantages: The construction is convenient, the original surface appearance will not be changed, and the surface hardness, compressive strength, abrasion resistance and impermeability will be significantly improved. Some liquid floor hardeners, such as VL-M2 cement floor sand treatment agent, have a more powerful hardening effect. Even if the cement floor is obviously sanded, it will become extremely hard through its hardening treatment, and the effect is permanent. of. Disadvantages: Some imported products are too costly and require too much of the original ground (most single-component products require ground floor strength above C25), and single-component products have comprehensive properties (especially hardness and wear resistance). The promotion of sex is limited; purely relying on the material itself can not improve the apparent effect of the original ground, and only with the grinding of the machine can the ground have a good brightness; also can not change the color of the original ground, only in the construction The foundation of the color corundum ground can make bright color ground. The ground of the modern industrial plant is being combined with the above two types of ground. In the case of solid concrete floor hardeners, the use of reliable liquid concrete 2. Use range For concrete floors that are resistant to abrasion and impact and reduce dust, such as: warehouses, docks, factories, parking lots, maintenance workshops, garages, warehouses, shopping malls, docks, and the need for uniform color to improve work environment and aesthetics while no corrosion Medium place. 3. Characteristics Strengthen the wear resistance and impact resistance of concrete floors. The density of the concrete is greatly increased, so that the dust generation is reduced, the oil repellency of the ground is increased, and a high-density, easy-to-clean, impervious floor is formed. Work together with concrete grounds, the construction period is short. The durability is good, reducing the cost due to periodic painting or thickening the surface. It is less dusty than a non-metallic hardened ground. The appearance is as glittering as a starry night. It is more resistant to shock and has a certain effect on anti-static electricity. 4. Process flow The first step: When the leveling layer is not leveled, the aggregate is evenly spread on the leveling layer; The second step: corner reinforcement, ground leveling; The third step is to saw the concrete in an appropriate position, make expansion joints, and fill the required joint filler; Step 4: Use a transparent sealer to roll, wipe, smooth, light, and maintain. The fifth step: wipe light, light, conservation. Editor's summary: The above is a description of the product features and application scope of the concrete floor hardener concrete floor hardener. The modern industrial factory floor is combining the above two types of ground, in the case of solid concrete floor hardener , The use of reliable quality liquid concrete floor hardener, with the finished machine ground surface, both the advantages of epoxy floor and corundum wear-resistant ground, while avoiding these two ground defects, it can be said that this is a Very popular industrial floor.
