CRM for Bonding to Concrete and Minimizing Concrete Crack in Civil Construction
Concrete reinforcing mesh with rectangular or square mesh pattern is a kind of welded wire fabric, which can improve the bonding to concrete, minimize
the concrete cracking that may occur as a result of concrete shrinkage. And the standard of reinforcing mesh is usually 6 m long × 2.4 m wide. With flat
even surface and firm structure, it is used extensively for re-enforcement of road surfaces, masonry walls, and concrete structures in building. Besides,
it is also can be used as large animal enclosure, quarantine caging, gabion or various fences.
