Introducing construction methods that can improve load-bearing capacity and durability.
The "Sprayed Floor Slab Thickness Increase Method" is a technique that involves spraying polymer cement mortar to increase thickness and integrate with existing concrete, thereby improving load-bearing capacity and durability. It can be applied to reinforce damaged road bridge RC slabs and beams due to insufficient load capacity caused by changes in design loads or fatigue deterioration from wheel loads. Additionally, it is applicable for bending and shear reinforcement of RC structures such as tunnels and box culverts. 【Features】 ■ Improved load-bearing capacity and durability ■ Reduced existing rebar stress and deflection ■ Restores the slab function and significantly enhances fatigue durability ■ Possible improvements in workability and cost-effectiveness *For more details, please download the PDF or feel free to contact us.
