Influence of cement type on heat of hydration and temperature rise of the mass concrete

Abstract

This paper provides experimental and analytical study results aiming to evaluate the effects of ternary cement types with different binder combinations on the heat of hydration in mass concrete by conducting the adiabatic temperature rise test and finite element thermal analysis of mass concrete mixtures with specified compressive strength of 30 MPa. A finite element thermal analysis for mat foundation with 15 m wide, 30 m long and 3 m thick were conducted based on concrete thermal properties from adiabatic temperature rise test. Test results reveal that concrete mixture mixed with Type IV cement displays the higher rate of heat evolution generated from hydration than those of concrete mixtures with ternary cements. It indicates that the ternary cements, which provide economic and environmental advantages by reducing Portland cement production and CO₂ emission, can be used as an alternative of Type IV cement for massive members.
