  • This study analyzed the temperature stress through mixtures mass concrete hydration heat analysis according to the replacement rates of FAC and CGS. As a result of the analysis, it was possible to confirm the effect of reducing hydration heat when CGS is substituted for the low heat mixture of mass concrete. However, the stress of the FAC+CGS combination exceeded the tensile stress. It is believed that it is necessary to apply the insulating sheet of the surface part and reduce the unit weight of cement.

  • In this study, adiabatic temperature rise of concrete depending on binder compositions and CGS contents is studied to provide informations for CGS low-heating aggregate and mixture designs for upper and lower placement lifts. Test nresults indicate that it is desirable to apply the combination of binders between top and bottom lift. For top lift, SESC or ESC is recommended, and for bottom lift, FAC+CGS 50 % is good for material composition.
