SpletThe rate of plastic shrinkage mainly depends upon the rate of evaporation of water and the temperature during the casting of the concrete. The plastic shrinkage of the concrete is higher if the cement content in the concrete is more. 5.2. Drying Shrinkage SpletPlastic shrinkage occurs when the water evaporates from the surface of fresh concrete. This may lead to plastic shrinkage cracking and normally they appear on the surface of …
SpletShrinkage is an inherent property of concrete. The shrinkage in concrete can be defined as the volume changes observed in concrete due to the loss of moisture at different stages due to different reasons. Contents: [ show] Types of Shrinkage in Concrete The shrinkages can be classified into the following: Plastic Shrinkage Drying Shrinkage SpletShrinkage of Concrete The property of diminishing in volume during the process of drying and hardening is termed Shrinkage. It depends mainly on the duration of exposure. If this strain is prevented, it produces tensile stress in the concrete and hence concrete develops cracks. 7. Modular ratio
