How is a silicon carbide wear-resistant floor constructed?
Due to its exceptional chemical properties—such as high hardness and excellent wear resistance—natural carborundum, when incorporated into floor-construction materials, imparts superior characteristics to the finished flooring, including high density, easy cleanability, and outstanding resistance to penetration. Consequently, in recent years it has been widely used in factories, workshops, parking lots, airports, schools, hospitals, and other facilities. Below, we will provide a detailed introduction. Introduce nature Carborundum wear-resistant flooring Method.
In simple terms, the entire construction process can be summarized as follows: concrete base pouring — leveling — first application and troweling of natural garnet aggregate — second application and troweling of aggregate — surface finishing and curing.
Step 1: Concrete base pouring and leveling: Due to its high hardness, excellent wear resistance, and other superior chemical properties, natural garnet sand, when added to floor-construction materials, imparts high density, easy cleanability, and excellent impermeability to the flooring. Consequently, in recent years it has been widely used in factories, workshops, parking lots, airports, schools, hospitals, and other facilities. The material is widely used. Today, Rizhao Natural Garnet Sand Manufacturer will provide a detailed introduction to the construction method for wear-resistant flooring using natural garnet sand.
Step 2: Concrete subbase placement and leveling: The key to this step is to use medium-grained sand and minimize or avoid the use of fly ash as an admixture. First, thoroughly clean the foundation to remove any loose particles and debris, then sprinkle water in advance to moisten the base while carefully controlling the water-to-cement ratio. Pour a concrete subbase of appropriate thickness. Concrete should be placed in a single pour to the required elevation whenever possible, ensuring uniform compaction and a smooth, level surface.
Step 3: While the leveling layer is still wet but has begun to set, evenly spread the aggregate over its surface. Variations in climate, temperature, and concrete properties can significantly affect the quality of a natural garnet wear-resistant floor. Spreading the aggregate too early may cause it to sink into the concrete, negating its effectiveness; spreading it too late, on the other hand, risks the concrete having already set, resulting in… This reduces bond strength, preventing the wear-resistant material from adhering properly and leading to delamination. During the initial setting of the concrete leveling layer, when light footprints are about 2–5 mm deep, slurry lifting and leveling can be performed. The application rate is approximately 4 kg per square meter; the first spreading should account for about three-fifths of the total material applied per unit area, with the aggregate falling evenly—avoiding forceful throwing that could After separation and spreading, smooth the surface with a wooden trowel to allow the aggregate to absorb a certain amount of moisture.
Step 4: Edge and corner reinforcement, and floor leveling: Areas along wall edges, column faces, door frames, and formwork tend to lose moisture more rapidly; therefore, these areas should be prioritized during application to prevent reduced performance due to dehydration. Use a cement troweling machine for mechanical smoothing, ensuring that the natural garnet aggregate bonds with the concrete substrate slurry. For edges and corners—areas where mechanical equipment cannot reach— For screeding, manual troweling is used; excessive tamping or pressing should be avoided.
Step 5: Second material spreading and troweling: During the second spreading, first use a straightedge to check the levelness and correct any uneven areas from the first spread. The amount of material used for the second spread should be approximately two-fifths of the total material applied per unit area, with faster-drying areas receiving additional material more quickly. Use the same method to perform the troweling. When operating the power trowel, advance in alternating longitudinal and transverse passes. Proceed evenly and in an orderly manner to prevent material accumulation, and finish the edges and corners with a wooden trowel.
After following the above procedures, the resulting silicon carbide wear-resistant floor coating meets quality standards, exhibits excellent gloss, and represents a highly desirable process option.
