Concrete wear-resistant floor is a healthy, wear-resistant, durable floor, he has nine wear-resistant hardness, super anti-heavy pressure, can withstand trailers, forklifts long-term pressure for 30 years can not afford dust sand, moisture, Anti-mildew, anti-aging, is the first choice for industrial ground floor, then, what is the characteristics of wear-resistant floor of concrete? Next, together with Xiao Bian look at the characteristics of concrete wear floor and concrete floor construction methods.
Concrete wear-resistant floor
Concrete wear-resistant floor, commonly known as 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.
Features
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.
Process flow
First, when the leveling layer is not dry, the aggregate is evenly spread on the leveling layer;
Second, corner reinforcement, ground leveling;
Third, saw the concrete in an appropriate position to make expansion joints and fill them with fillers;
Fourth, with a transparent sealer roller, electric trowel smear, wipe light, light, maintenance.
Fifth, wipe light, light, conservation.
Concrete floor construction method
one. Construction preparation
1. Elevation detection point: Φ12 steel bars are fixed on the surface of the original concrete with expansion bolts, and the height exceeds the surface of the structure by 150mm. Levels are recorded with a level meter, and +100mm lines are laid on the steel bars (including columns and wall surfaces), marked with red paint.
2. Fine stone concrete ash cake setting: According to the completed elevation detection point, pull wire set fine stone concrete elevation control point, the size is 30*30, placed on the white ceramic tile (taken out when the flat), the elevation accuracy is controlled at -5mm~ +2mm, super high is strictly prohibited to prevent the concrete surface from protruding.
3. Before the concrete is poured, it is necessary to remove the impurities from the original concrete slab, and moisten the water one day in advance (should be responsible for the special person), and remove the accumulated water before pouring the concrete.
4. Equipped with sufficient vibrating tool, insert vibrator, plate vibrator, and spare (various vibrator, vibrator), trolley
5. Concrete workers: 2 (classes), and another organization of emergency personnel on standby, electricians, mechanics, mechanics (specific numbers of decoration companies to make their own arrangements).
two. Concrete pouring
1. Concrete transportation: Horizontal transport with two concrete pumps and trolleys.
2. Concrete pouring, treatment of pump pipe water and mortar, vibrating concrete, bleeding treatment, prevention of cold joints
three. Guarantee measures
1. Illumination: In the four corners of the pouring range, a xenon lamp is set, and a 6 to 8 (fixed type) iodine-tungsten lamp is provided, and a mobile iodine-tungsten lamp: 4 lamps and a plurality of lamps (standby).
2. Column angle treatment: In advance, the column elevation control line +100mm pops up on the steel bars of the column, and the column line confirms the elevation is correct. Then, the wood mold is closed to ensure that the four-corner column mouth must be flush and beautiful.
3. The degree of concrete pouring must be determined according to the initial setting time of the concrete and the leveling work of the concrete and the construction time of the wear-resistant floor. The amplitude must not be too large.
4. The expansion joint cover bracket is installed before the concrete floor is poured.
Summary: The relevant information on concrete wear-resistant flooring and concrete floor construction methods was introduced here. I hope this article will be helpful to everyone. If you still have something you don't understand, you can leave a message to Xiaobian at the bottom. We will answer your questions as soon as possible.
