What is concrete floor hardener? The concrete ground hardener is a material for wear-resistant and hardened ground, commonly known as emery floor, which is directly constructed on the concrete surface at the initial setting stage. Since its inception in the 1970s, the ground hardener has been rapidly popularized in Europe and the United States, and has become a perfect replacement product for terrazzo flooring. In the late 1980s, wear-resistant flooring is the first choice in developed countries. If you have this need, you might as well join me to learn about the relevant knowledge of concrete floor hardener

concrete floor hardener

1 Classification

I. powdered cement-based solid ground hardener: also known as wear-resistant ground (flat), emery ground (flat), cement-based aggregate wear-resistant ground (flat), etc. It is the best substitute for terrazzo floor

1. Composition of concrete floor hardener material: it is a cement-based powder material premixed in the factory, which is mainly composed of high-grade cement, wear-resistant aggregate (quartz sand, emery, alloy aggregate, etc.), pigment powder (gray, red, green, blue, yellow), concrete additive (water reducer, etc.)

2. Construction process: pouring base course concrete, leveling, lifting slurry, removing excess bleeding &mdash& mdash; Spreading concrete floor hardener &mdash& mdash; Trowel compaction, troweling &mdash& mdash; Apply curing compound &mdash& mdash; Cut expansion joints

3. Advantages: fast construction speed (basically completed at the same time as the base concrete ground) and little environmental pollution during construction; Low cost, good wear resistance, hardness and impact resistance; The surface is smooth and can be colored. In general, this solid hardener floor is an economic and practical industrial floor

4. Disadvantages: compared with epoxy floor, the aesthetics is slightly poor, and there will be obvious color difference on the colored concrete hardener floor; The ground formed by concrete ground hardener is actually a kind of concrete ground. Although its compactness and hardness are significantly better than ordinary concrete ground, its interior is still a microporous structure, and its impermeability (especially oil impermeability), antifouling performance and easy cleaning performance are far inferior to epoxy floor. Therefore, it is not recommended to use concrete floor hardener for the use occasions with high requirements for ground cleanliness, or the ground with frequent oil dripping

5. Generally, it is recommended to use concrete floor hardener for occasions that do not require high cleanliness or aesthetics and focus on economic, practical and durable

II. Liquid concrete floor hardener: also known as cement floor sanding treatment agent, concrete sealing and curing agent, liquid floor hardener, concrete surface reinforcement agent, concrete penetration hardener, etc

this is a water-soluble chemical hardener, which generates a large number of gel through a series of chemical reactions with the by-products of cement hydration. This gel can block the pores in the concrete, so the compactness and hardness of the concrete floor are adjusted. The chemical reaction of some two-component liquid floor hardeners is more complex, which not only generates gel, but also generates some stable calcium silicate hardeners, thus greatly improving the surface hardness, strength and compactness of cement concrete floors

1. Main material composition: alkali silicate with reactive activity, or modified active silicate, surfactant, catalyst, etc. Some liquid floor hardeners also contain fluorosilicates

2. It cannot be mixed with concrete or cement mortar, and only the formed cement or concrete ground can be used. It works by penetrating into the concrete floor, without changing the appearance of the original floor

3. Advantages: the construction is convenient and will not change the appearance of the original ground, and the surface hardness, compressive strength, wear resistance and impermeability are significantly improved. Some liquid ground hardeners, such as vl-m2 cement ground sanding treatment agent, have a stronger hardening effect. Even the cement ground with obvious sanding will become extremely hard through its hardening treatment, and the effect is permanent

4. Disadvantages: the cost of some imported products is too high, and the requirements for the original ground are too high (most single component products require the strength of the base floor to be above C25), and the improvement of the comprehensive performance (especially the hardness and wear resistance) of single component products is limited; Relying solely on the material itself cannot improve the apparent effect of the original ground. Only when it is polished with the machine can the ground have good brightness; Nor can we change the color of the original ground. Only on the basis of the colored emery ground that has been constructed can we make a bright ground

modern industrial plant floors are combining the above two kinds of floors. Under the condition that solid concrete floor hardener has been prepared, reliable liquid concrete

2 is used Scope of use

it is used for concrete floors that must be wear-resistant, impact resistant and reduce dust, such as warehouses, docks, factories, parking lots, maintenance workshops, garages, warehouse malls, docks and places that need unified colors to improve the working health environment and beauty without corrosive media

3. Characteristics

enhance the wear resistance and impact resistance of the concrete floor. It greatly improves the density of concrete, reduces dust, increases the oil resistance of the ground, and forms a high-density, easy to clean and impermeable ground. It is constructed together with the concrete floor, and the construction period is short. Good durability, reducing the cost caused by periodic coating or surface thickening. It has less dust than the non-metallic hardened ground, looks like a starry night, has better impact resistance, and has a certain effect on anti-static

4. Process flow

step 1: when the leveling layer is not dry, evenly distribute the aggregate on the leveling layer

step 2: reinforce the corners and smooth the ground

step 3: saw the concrete at the appropriate position, make expansion joints, and fill up the required joint filler

step 4: roll with transparent sealant, trowel, trowel, polish and maintain

step 5: trowel, polish and maintain

editor's summary: the above is what is the concrete floor hardener. The product characteristics and application scope of the cement floor hardener are introduced. The modern industrial plant floor is combining the above two kinds of floors. Under the condition that the solid concrete floor hardener has been prepared, the liquid concrete floor hardener with reliable quality is used, together with the finished floor after machine polishing, It has both the advantages of epoxy floor and emery wear-resistant floor, and avoids the shortcomings of these two kinds of floor. It can be said that this is a very promotional industrial floor
