Control of Thermal Cracking in Mass Concrete with Blast-Furnace Slag Cement

The purpose of this study is to improve crack resistance of mass concrete with blast-furnace slag cement. The fineness of blast-furnace slag, the slag content, and the content of gypsum were varied, and the effects of these factors on autogenous shrinkage and adiabatic temperature rise of concrete were experimentally investigated. Based on the experiments, blast-furnace slag cement with low heat of hydration and low autogenous shrinkage, which complies with the requirements of JIS R 5211, was proposed. It was proved from restraint stress tests and applications to mass concrete structures that thermal cracking at early ages could be effectively controlled by using the proposed blast-furnace slag cement.
