Such cracking is inevitable in many situations and a significant amount of reinforcement crossing each crack is required for crack control. Contractor Solutions Contractors need to understand the risks from heat of hydration.
Published by Elsevier Ltd. We can also advise on whether the Contractor was responsible for cracks or whether the cracks stem from design and specification limitations. However, Intelli-Rock temperature loggers are often the most efficient means for the contractor to log and report temperatures. They also have 32 channel strain loggers to record thermal strains.

Early-age thermal crack control in concrete
Finding libraries that hold this item Boddington – BCRC undertaook an analysis of crack widths expecated in an end restraint situation. The Red document status indicator indicates that the document is an old version The document has likely been withdrawn by the publisher, also the meta data presented here may be out of date as it is no longer being viria by the editorial teams at NBS.

BCRC also provide a service for assessment of insitu strength using maturity. As concrete hydrates there is an exothermic reaction and the insitu temperature rise can cause a range of problems. I would assume if you buy a hard copy from Curia it will come with it. BCRC are able to undertake insitu monitoring to measure the maximum temperature rise and differential.

Early-age thermal crack control in concrete (Computer file, ) 
This is the essential heat generating signature of the concrete mix that is used in modelling insitu temperature. Considers design aspects such as estimating the magnitude of crack-inducing strain, how to control the size of cracks using reinforcement and ways to minimise risk.

Thermal and Cracking Assessment As concrete d660 there is an exothermic reaction and the insitu temperature rise can cause a range of problems. This phenomena happens when tensile cirla is greater than the tensile strain capacity of concrete.
