Ensuring that the concrete is damp can increase the strength of the concrete during the early stages of curing. This is achieved through techniques such as spraying concrete slabs with compounds that create a film over the concrete that retains water, as well as ponding, where concrete is submerged in water and wrapped in plastic.

Torsional Strength of Reinforced Concrete Members Failing by Crushing

Date: 11/1/2022. The torsional strength of reinforced concrete members that fail by yielding of the reinforcement can be accurately predicted by design codes such as ACI 318-19 and the Canadian design standard CSA A23.3:19. However, these codes are relatively poor at predicting the strength of heavily reinforced members that fail by crushing.
