WebOct 4, 2024 · Early-age thermal cracking occurs when the tensile strain, arising from either restrained thermal contraction or a temperature differential, exceeds the tensile strain capacity of the concrete. In high strength concretes autogenous shrinkage may also contribute to early contraction. It is proposed to minimise the number of movement joints … WebMitigating early-age cracks in concrete structures is critical for sufficient durability, avoiding possible strength reduction, and reducing maintenance costs. ... During the design process, restraints in various concrete elements should be followed as they restrict concrete movements due to thermal expansion and autogenous shrinkage. Cracks ...
Webbreakwaters, especially dealing with thermal stresses due to the heat of hydration (Dechaene et al 1994). A new simulation method for early age concrete thermal cracking has been developed, entirely based on the degree of hydration, including basic creep behaviour and basic shrinkage. A short overview of the simulation method is presented.
