How Is The Wear Resistance Of Anti Slip Terrazzo Reflected in Schools?

The wear resistance exhibited by anti slip terrazzo in school settings is achieved through the synergistic effect of material properties, structural design, and actual usage scenarios, specifically reflected in the following aspects:

1. Material composition: Dual guarantee of hard aggregate and high-strength matrix
Hard aggregate: Anti slip terrazzo usually uses high hardness natural aggregates such as quartz sand and granite fragments, with a Mohs hardness of 6-7 levels (close to steel), which can resist frequent friction from objects such as shoe soles, table and chair legs. For example, school corridors bear thousands of student walks every day, and hard aggregates can effectively reduce surface wear and tear.
Cement matrix: High grade cement (such as C40 and above) is used as a binder to form a dense structure and enhance overall compressive strength. Laboratory tests have shown that the compressive strength of high-quality terrazzo can reach 40-50 MPa, far exceeding that of ordinary floor tiles (about 20-30 MPa), making it suitable for high pedestrian flow areas.

2. Surface treatment process: balance between slip resistance and wear resistance
Polishing and Marking Technology: During construction, mechanical polishing is used to compact the surface, while fine grooves (such as lychee surface and fire burned surface treatment) are carved to increase friction and prevent slipping. The pressure is also dispersed through concave convex structures to reduce local wear. For example, the cafeteria floor is prone to slipping due to oil stains, and the anti slip terrazzo can reduce the accident rate by more than 30% through surface texture design.
Sealing agent protection: Apply epoxy resin or fluorocarbon sealing agent to form a transparent protective layer, block water and oil infiltration, and enhance surface hardness. Tests have shown that the wear resistance of terrazzo after sealing treatment is improved by 2-3 times, and the service life is extended to more than 10 years.
3. Structural design: Optimization for school scenarios
Partition design: Adjust the aggregate particle size and ratio according to the frequency of use. For example, coarse aggregate (particle size 8-12mm) is used at the classroom entrance to enhance wear resistance, while fine aggregate (particle size 3-5mm) is used in quiet areas such as libraries to balance aesthetics and comfort.
Joint treatment: Use elastic sealant to fill expansion joints to prevent cracking caused by thermal expansion and contraction. A case study from a certain middle school shows that reasonable joint design reduces the cracking rate of the ground by 80% and maintenance costs by 50%.
4. Verification of actual usage scenarios
High frequency usage areas: Stairs, corridors, and other areas are subjected to thousands of stampedes every day. Anti slip terrazzo is treated with hard aggregates and seals, with a surface wear rate of less than 0.1mm/year, far better than ordinary floor tiles (about 0.3-0.5mm/year).
Heavy object handling test: The laboratory simulates the dragging of heavy objects such as desks and instrument carts, and there are no obvious scratches on the surface of the terrazzo, while the PVC floor may leave permanent damage.
Long term weather resistance: The outdoor playground stands are made of anti slip terrazzo. After 5 years of sun and rain exposure, the surface friction coefficient remains above 0.6 (safety standard ≥ 0.5), and the wear-resistant layer does not peel off.

5. Maintenance convenience: reduce long-term costs
Daily cleaning: The anti slip terrazzo surface is dense, and stains are not easy to penetrate. It can be restored to cleanliness by rinsing with clean water, reducing the use of chemical cleaning agents.
Local repair: If there is local wear, it can be repaired by polishing and reapplying sealant, with a cost of only one-third of replacing the floor tiles.
data support
Wear resistance test: According to the "Code for Acceptance of Construction Quality of Building Ground Engineering" (GB50209), the wear amount of anti slip terrazzo is ≤ 0.5g/cm ² (ordinary floor tiles ≥ 1.0g/cm ²).
Anti slip coefficient: Dry friction coefficient ≥ 0.6, wet friction coefficient ≥ 0.5, in compliance with school safety standards (such as EN 13414).
Service life: High quality anti slip terrazzo can last for 15-20 years, while ordinary floor tiles take about 8-10 years.
Conclusion
Anti slip terrazzo exhibits excellent wear resistance in high-frequency usage scenarios such as school corridors, classrooms, and canteens through hard aggregates, high-strength substrates, surface anti slip treatment, and structural optimization. Its long-term weather resistance, low maintenance cost, and safety performance make it an ideal choice for school flooring materials.
