Temperature Rise of Cement Blends

The study aims to investigate the temperature rise of various concrete binders under adiabatic conditions, which is particularly critical for mass concrete structures. It seeks to evaluate the effect of the amount of binder and the water-binder ratio on the temperature rise of concrete as well as its compressive strength. The study is carried out using a Temperature Match Curing System which replicates the adiabatic conditions inside a mass concrete structure as it hydrates. To investigate the temperature rise of various binders, fly ash, silica fume, and ground granulated blast furnace slag were used as partial cement replacement. Each material had two levels of replacement and each replacement level was investigated using four different amounts of binder. The temperature rise of various binders were evaluated in terms of the maximum adiabatic temperature rise and the time when this is reached. The blended cements all had a lower adiabatic temperature rise compared to the ordinary portland cement concrete while maintaining similar compressive strengths.
