Best Practices in Precast: Concrete Cracking

2019-4-28 · Some times drying shrinkage occurs where the concrete is exposed to the air while still in the form. The water evaporates more rapidly on exposed surfaces, and therefore the precast element contains small micro-cracks. In reinforced concrete,

Types & Summary of Cracks in Reinforced Concrete Beams

Flexure word also means “Bending”. Cracking in reinforced concrete beams subjected to bending usually starts in the tensile zone i.e. soffit of the beam. The width of flexural cracks in reinforced concrete beams for short-term may stay narrow from the sur
