What is the surface hardener construction technology for ground hardener
Ground hardener is a hard-wearing ground, commonly known as a corundum floor. Emery ground floor is the common name for domestic hardwearing and hardened floor. Foreign enterprises call it " ground hardener ". Applicable to industrial sites, docks, parking lots, commercial stores, logistics warehouses and other ground decoration needs, with wear and compression resistance, reduce dust, hard surface, easy to clean, economical and durable. The main components of aggregates are Al2O3, Fe2O3, TiO2 and other metal oxides or metal aggregates.
Ground Hardener Introduction
Ground hardener is a hard-wearing ground, commonly known as a corundum floor. 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.
The mineral alloy aggregate (corundum) ground hardener consists of a certain amount of mineral aggregate aggregate, special cement, other admixtures and admixtures, which can be used after opening the bag. It is evenly spread on the surface of the concrete that is about the initial setting stage, and is processed by special means so as to form a whole with the concrete floor and has a high-density and coloring high-performance wear-resistant floor.
Ground hardener range of use
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.
Hardening agent properties
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.
Ground hardener construction process
Emery ground floor is the common name for domestic hardwearing and hardened floor. Foreign enterprises call it "ground hardener". Applicable to industrial sites, docks, parking lots, commercial stores, logistics warehouses and other ground decoration needs, with wear and compression resistance, reduce dust, hard surface, easy to clean, economical and durable. . The main components of aggregates are Al2O3, Fe2O3, TiO2 and other metal oxides or metal aggregates.
Baseline requirements and usage control
1) Use premixed concrete (strength grade C25 and above), cement dosage ≥300kg/M3, fly ash content ≤10% (abrasion resistant material dosage 5kg/M2).
2) Strictly control the concrete raw materials, the water-cement ratio should be 0.5 ± 0.05.
3) Material usage control: Emery: 5-6KG/m2
Standard construction practices
A: Base concrete mixing and filling
Construction requirements: equal proportions of sand, stones, cement, and water are mixed evenly; the thickness of the screed-base screed requires a thickness of 30mm-50mmM or more, the strength is more than C25, the minimum cementitious material content is, and the slump of the site is 75-100mm, The surface should be dense, smooth, and free from bleeding.
Construction taboo: During the process, avoid splashing water on the surface.
Two: Grassroots harvesting
Construction requirements: When the ground floor concrete is first set (about 2~3h), wearable floor construction can be carried out. The disc is first installed on the trowel, the whole is polished and gradually transferred from the periphery to the inner surface to smooth and pick up the slurry. effect.
Note: The initial setting time should be determined according to the operating environment, climate and other circumstances. General foot depression is not more than 5mm to start the laying of emery wear-resistant material.
Three: The first time to spread the diamond
Construction requirements: The first time spreading 2/3 of the silicon carbide material evenly spread on the surface of the crucible (evenly scraped with a scraper) until the material absorbs the water in the crucible, and the surface begins to turn gray after the darkening color begins. Time wiped.
Four: kneading, smoothing
Construction requirements: Use a trowel with a disc to grind and disperse it so that it can be combined with the concrete slurry of the grass-roots level. The wall can be iron kneaded manually and flattened.
V: Second Laying Emery
Construction requirements: The remaining 1/3 of the material shop will be scattered on the concrete surface, and the direction of spreading will be perpendicular to the first time. The second leveling work will be carried out. Finally, the troweling machine equipped with a blade is used to complete the troweling work.
Six: Recover
Construction requirements: adjust the blade inclination angle (speed and angle depending on the hardening condition) with the setting time of the concrete. The trowel operation is criss-cross (3 times or more). The corners of the corners are galvanized in the same direction with an artificial steel trowel to avoid the appearance of moire.
Seven: Maintenance
Construction requirements: 4 hours after the completion of the construction, spray special protective agent for the silicon carbide floor for 7 days.
Construction Notes
1. The single pouring area should not be too large and should be controlled below 800m2. When the side die is used, the mold release agent is used to separate the positions. When the bins are not straight, they should be straightened with the cutting machine's bullet line before the next construction. The seams should be consistent with the position of the sub-grid seam after the floor is formed.
2. When constructing the corners and columns of the wall columns, it should be vibrated and compacted, and then use artificial pulp.
3, the concrete surface elevation control is less than 3mm/2m (to have flatness guarantee measures).
4, avoid open-air operations, during the construction period and within 4 hours after the completion of construction is prohibited from contact with rain, 8 hours can open traffic
5, depending on the ambient humidity and the concrete used for the foundation concrete. Usually 24-48 hours later
Editor's summary: The relevant information on what is the surface hardening agent and surface hardening agent construction process is introduced here for everyone.
