Abstract:
Ground Granulated Blast Furnace Slag is widely used as a partial replacement of cement in mass concrete structures. However, the effect of slag towards thermal properties in mass concrete is not extensively investigated. Predicting thermal properties and adiabatic temperature rise are essentially useful for investigating thermal cracking potential especially at early stage of mass concrete. Existing prediction methods and models have some problems such as constant thermal properties are mostly utilized for predicting temperature rise of mass concrete. These assumptions lead to errors and inaccurate predictions of temperature and thermal cracking potentials especially at the early stage where thermal properties tend to change rapidly. Therefore accurate modelling of thermal properties could be beneficial to provide solid background to accurately predicting thermal cracking of mass concrete. This study is aimed to develop time-dependent models for predicting hydration degrees of cement and slag which are vital parameters in modeling many properties of concrete. Then the models of free water, specific heat, thermal conductivity, coefficient of thermal expansion, and total heat generation of concrete including slag are modified. These models are then composed to predict the adiabatic temperature rise of mass concrete incorporating slag. The model simulations can be used to accurately predict the experimentally measured data from different sources. Moreover, semi-adiabatic temperature rises of concrete with fly ash and slag are evaluated experimentally. The 28-day compressive strength model and initial slump model are verified with the test results of concrete mixtures containing different replacement levels of fly ash and slag
