This document specifies the procedure for the determination of heat released by concrete during its hardening process in semi-adiabatic conditions in a laboratory. Annex B specifies the procedure when the test is performed on site. The test is suitable for specimens having a declared value of D of the coarsest fraction of aggregates actually used in the concrete (Dmax) not greater than 32 mm.<\/p>\n
