- To understand when cracking is most likely
- To appreciate the significance of cracking
- To have methods for its avoidance and/or control
Who should read this?
Anyone who primarily for designers, but information is also included to support contractors.
This 113-page book gives a method for checking that the reinforcement provided will be sufficient to control early-age cracking that may develop due to temperature change and shrinkage.
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. Numerous factors influence the risk of early-age cracking including the temperature rise; the coefficient of thermal expansion of the concrete; the restraint to movement offered either by adjacent elements or by differential strain within an element; and the ability of the concrete to resist tensile strain.
This book is compatible with EN1992-3:2006 and EN1992-1-1 with regard to the properties of concrete and the design of reinforcement.
