Construction method with high strength and abrasive resistance

Preparation for construction:

Clean up the debris on the surface of the base, and there shall be no debris such as gravel, floating slurry, floating ash and release agent. Any loose parts on the foundation surface should be removed;

Wet with water 24 hours in advance, remove water 1 hour before construction, and fully chisel the surface layer;

Lay wire mesh.

Mixing of abrasive resistant materials:

The mechanical mixing time is 2-3 minutes: when stirring artificially, 2/3 of the water should be added first and mixed for 4 minutes, and then the remaining water should be added to stir until the construction workability is met.

Each mixing material mixed with water to the completion of construction should be completed within 40 minutes, prohibit infiltration of any admixture.

Flatten:

2 hours in advance, use a brush or rolling brush to evenly paint the interface agent, and then use a steel spatula to layer the wear-resistant fabric, the thickness of each layer should not exceed 30mm, and press hard in the process of pressing.

Maintenance:

Wet grass bag or rock quilt should be covered within 30 minutes after matting, and moisturized and maintained for at least 7 days. And should comply with the "concrete structure engineering construction quality acceptance Code" in the relevant provisions.
