Concrete is essential in many modern structures, from buildings to bridges and dams. Strengthening and reinforcing the material is essential in ensuring its strength and durability. Unfortunately,
Vibration is one of the methods used to consolidate poured concrete to achieve required density and, subsequently, the designated concrete strength. Vibrators (internal and external or shutter vibr
Dry shake hardener is a mixture of cement, aggregate, and admixture which is applied as a dry compound onto the fresh concrete surface to protect floor surface from abrasion and impact effects, pro
Concrete is not normally designed to resist direct tension. However, tensile stresses develops in concrete members as a result of flexure, shrinkage and temperature changes. Principal tensile stres
Dry pack mortar is used to repair the concrete surfaces which contains cracks or holes of depth larger than or equal to the least dimension of the repair area. The holes generally found on concrete
