The wear-resistant floor has been rapidly popularized in Europe and the United States since the advent of the 70s of the last century and has become a perfect replacement for terrazzo wear-resistant flooring. Into the late 80s, wear-resistant floor is the first choice for developed countries. In the construction industry, in order for the ground to meet a certain performance, such as wear, dust, moisture, etc., it is necessary to lay a corresponding wear-resistant floor on the ground, in which the wear-resistant floor is currently used more floors, He has excellent comprehensive performances such as wear resistance, compression resistance, and dust-free sand. So, what is the wear-resistant floor construction process ? Below, take a look at Ping.
Wearable floor classification
Non-metallic type
The non-metallic wear-resistant floor is composed of selected aggregates with certain particle size grading, high-strength cement, special admixtures, pigments and polymers, and can form a layer of dense colored wear-resistant surface layer on the foundation concrete. Good impact resistance. Can be widely used in shopping malls, large supermarkets, sidewalks, parking lots, production workshops,
Machine repair workshops, warehouses and other places that require special enhancement of surface abrasion resistance can be used both indoors and outdoors, even if they are in a wet state for a long time, it will not affect its performance. According to the requirements of the ground wear layer (1.5-3.5mm), the recommended dosage is 5-7kg. The main technical indicators of the quartz sand type wear-resisting floor system: 28 days flexural strength 12MPa 28 days compressive strength 85MPa surface hardness, mm (indentation diameter) 2.8 wear resistance ratio.
Metal type
The metal wear-resisting floor is composed of selected aggregates with certain particle size grading, high-strength cement, special admixtures, pigments and polymers, and is distributed in the concrete surface of the initial setting stage evenly by dry-type spraying method. With the construction of professional construction tools, a layer of extremely dense, high-strength colored wear-resistant surface layer can be formed on the foundation concrete. Hardwearing agents are available in 4 colors (cement color, gray, red, green), which have the advantages of good bonding with the foundation concrete, compact surface, high abrasion resistance and strong impact resistance. It can be widely applied to concrete surfaces that require special enhancement of surface abrasion resistance and impact resistance.
Such as production and processing workshops, machine maintenance workshops, warehouses and other places, its disadvantages are not suitable for the ground in long-term wet environment, often contact with the ground of acidic, crystalline salt and other chemical solvents. According to the requirements of the ground wear layer (1.5-3.5mm).
Alloy aggregate
Alloy aggregates wear-resistant floor materials Mineral alloy aggregates (tin-titanium alloy) Wear-resistant materials consist of a certain amount of mineral aggregate aggregate, special cement, miscellaneous miscellaneous materials and admixtures, and can be used after opening the bag. It is evenly spread on the surface of the concrete, which is about the initial setting stage, and is processed by special means so as to form a whole with the concrete floor, and the high surname with high density and color can wear the ground. Features: Strengthen the wear resistance of concrete floors, impact resistance character strength. The density of the concrete is greatly increased, so that it does not cause dusting, increases the oil repellency of the ground, and forms a high-density, easy-to-clean, anti-permeability floor together with the concrete floor. Resistance to heavy pressure, strong abrasion resistance, no dust, enhanced oil resistance on the ground, resistance to infiltration, and cleanliness.
Construction preparation
1. Construction equipment: According to the construction area and progress, prepare enough construction machinery, tools and corresponding supporting facilities.
2. Hydropower is in place: Party A should assist in solving construction and domestic water use. Construction uses 380V and 220V, and lighting uses 220V.
3. Material organization: Do a good job of budgeting materials and supplying materials in a timely manner. After the materials are on the site, they will be arranged in a unified manner and placed in warehouses.
4. Personnel organization: Technical personnel, safety personnel, material personnel, and construction personnel are in place to cooperate with the project manager to prepare for construction.
5, technical disclosure: construction technology management personnel should carry out the technical disclosure of floor engineering, and construction workers on the site construction of the safety of work.
Wear-resistant floor construction process
When the grassroots initial setting, spread the aggregate, and strive to spread evenly, sprinkle the material twice, and ensure the amount;
1. Spread 2/3 of the total amount for the first time and compact the bristles with polished discs;
2. Spread 1/3 of the total amount for the second time and use a lighted disc to compact the bristles;
3. After the initial setting, wipe it with a calender;
4. Check the smoothness of the material after spraying, adjust the material in time for the low-lying area, and compact the armpits and wipe the light at the place;
5, before finishing, polishing with a trowel machine to achieve the completion of the process;
6, uniform coating of ground curing agent.
Oil resistance: The wearable ground itself does not have oil resistance. If you want to achieve good impermeability and oil resistance, you can use HOPER liquid hardener, concrete seal curing agent so that the surface of the wear-resistant surface has better compactness, to achieve good impermeability, and can improve the wear resistance of the ground And glossiness.
Corrosion Resistance: Aggregate standard salt corrosion test. For 42 days, natural telecommunication constant is positive and stable value +0.5mm (SCE), maximum +120MV (SCE) cement sample, 5% NACI solution soak, 2 years and 3 years. There are no rust spots in the month.
Floor maintenance: After the wear-resistant floor is completed (depending on the weather conditions), water is added to the PVC film or special curing agent, and the surface of the wear-resistant floor is applied for curing to prevent its surface water from evaporating violently to ensure the strength of the wear-resistant floor. Stability, conservation time is seven days.
Summary: The relevant information on the category of wear-resistant flooring and construction technology of wear-resistant flooring 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.
