How big a hammer does it take to smash a meter thick cement?
The maximum particle size of gravel coarse aggregate used in one-meter-thick cement should not be greater than three times the thickness of the surface layer, and the particle size of gravel used in fine stone concrete surface layer should not be greater than 15mm, so generally speaking, a 70cm hammer should be used for one-meter-thick cement.
Precautions for cementing:
When cement is applied, when the static load or live load is large, it is appropriate to configure steel bars or add steel fibers in the concrete cushion according to the load calculation, and the tensile strength of steel fibers should not be less than 1000MPa.
The flexural toughness ratio of steel fiber reinforced concrete should not be less than 0.5. When the cushion is only used for structural reinforcement, steel mesh with the diameter of 14mm and the spacing of 1200mm can be configured.
