Heat of Hydration and Cracking Assessment

BCRC were able to show that the contractors proposed 75mm of insulation was far too thick and the concrete would take a long time to cool before it could be stripped. Some features of WorldCat will not be available.

On the more positive side BCRC can also help contractors use the heat of hydration. As concrete hydrates there is an exothermic reaction and the insitu temperature rise can cause a range of problems.
