Shrinkage Cracking in Concrete Structures | Long Term Effects

Shrinkage crack

Long-term Shrinkage Cracking of Concrete Internal or external restraints in a concrete structural element may resist free shrinkage of concrete, over time this leads to Shrinkage Cracking. In concrete structures, the volumetric reduction that happen due to the loss of moisture by evaporation is known as the shrinkage of concrete. This deformation is time dependent … Read more Shrinkage Cracking in Concrete Structures | Long Term Effects

Soil Nailing | Principles | Advantages

Soil-nailing-done-to-protect-the-highway

Soil Nailing Soil nailing is a ground improvement technique which is used to reinforce soil to make it more stable. Soil nailing is used for slopes, excavations, retaining walls etc. to make it more stable. The faces of steep slopes are usually protected by shotcrete and mesh for temporary works and by either cast-in-place concrete … Read more Soil Nailing | Principles | Advantages
