Grit sand ground hardener is composed of mineral alloy aggregates of a certain particle size, special cement, other admixtures, and additives, ready for use straight out of the bag. It should be evenly sprinkled on the concrete surface in the early setting stage. The amount of wear-resistant material is determined according to the material instructions and design requirements.

I. Applicable Locations:

Ideal for most industrial buildings, underground parking garages, heavy machinery factories, auto repair shops, warehouses, plazas, docks, parking lots, and warehousing supermarkets, especially areas with vehicle traffic.

Performance Features:

The cured surface boasts high hardness and excellent wear resistance.

2. The ground can withstand large impact loads.

3. Achieves complete adhesion with the base concrete, with no bubbling or peeling.

4. Daily cleaning is convenient and simple, saving materials and reducing costs.

5. Construction thickness: 3-5mm; service life synchronized with the original concrete surface

Section Two: Construction Equipment

Planetary vibrators, mortar mixers, concrete smoothing machines, stainless steel straightedges, wood trowels, iron trowels, buckets, sprayers, hand trucks, and other tools are also prepared.

(1) Suction Tools:Rubber Hoses or Vacuum Suction Equipment.

(2) Leveling Paste Tool: A Φ150 steel pipe filled with sand in the center, longer than the width of the ground mold by more than 500mm, with rotating handles at both ends.

(3) Flat-bottomed rubber shoes: Used after concrete has started to set; Waterproof paper shoes or waterproof paper bags; Surface leaf polishing application.

Process Flow:

Concrete base pouring -- Levelling --金刚砂 aggregate secondary spreading and smoothing -- Aggregate secondary spreading and smoothing -- Surface finishing and maintenance

1) Specific construction techniques

1. After the concrete pouring and leveling, the surface is troweled and smoothed with a polishing machine disc before the concrete starts to set. During the smoothing process, attention should be given to the presence of any excess slurry on the surface. If there is any, it should be manually scraped off. The purpose of smoothing is to ensure a complete bond between the hardening agent material and the concrete. Any large aggregates (stone pieces) floating on the surface should be removed during the smoothing process.

2. The timing of aggregate spreading varies with factors such as climate, temperature, and concrete mix ratios. Spreading too early can cause the wear-resistant material to sink into the concrete, losing its effectiveness. Spreading too late, when the concrete has set, results in a loss of adhesion, preventing the wear-resistant material from bonding and causing peeling. During the initial setting of the concrete leveling layer, when light footprints are about 2-5mm deep, it is possible to perform slurry topping and leveling.

3. Evenly spread the required silicon carbide hardening aggregates on the concrete surface, with an approximate usage of 4kg per square meter. Areas such as walls, columns, doors, and formwork edges lose moisture faster, so they should be prioritized in the application to prevent reduced effectiveness due to moisture loss.

4. The amount of spreading should be approximately 3/5 of the total material input per unit area. The aggregates should fall evenly and not be thrown with force to avoid separation. After spreading, use a wooden trowel to level the surface, allowing the aggregates to absorb some moisture.

5. Use a cement trowel to mechanically smooth the surface, ensuring the aggregates are bonded with the concrete subbase mortar. For edges and corners where mechanical smoothing is not possible, manual smoothing is employed, avoiding excessive pressing.

6. When spreading the material, first measure the level with a straightedge and adjust any uneven spots. The spread amount should be approximately 2/5 of the total material dosage per unit area, and increase the spreading rate for areas that lose moisture quickly. Flatten using the same method. During the operation of the paste glazer, perform longitudinal and transverse interlocking to ensure even and orderly spreading, preventing material from gathering. Use a wooden spatula to handle the edges and corners.

When the surface material hardens to the point where it slightly sinks upon finger pressure, adjust the speed and angle of the Mo Guan machine according to the degree of hardening.

Once the surface starts to set and the slurry begins to solidify, perform a final smoothing.
