  • Abstract:
    Following specification harmonization for portland cements, FDOT engineers reported signs of

    deterioration in concrete elements due to temperature rise effects. One of the main factors that affect

    concrete temperature rise potential is the heat generated by portland cement during hydration. This study

    was initiated to identify the effect of cement fineness on the heat generated by portland cement. Eleven

    cements were selected for this study to address the effects of cement fineness and mineralogy. Several

    of the cements came from the same source but had different grinds. This was important in studying the

    fineness contribution to heat of hydration while maintaining similar cement mineralogy. The as-received

    cements from different suppliers had a wide range of mineralogical compositions which allowed the

    study of the effects of mineralogy on the heat of hydration. Cements were characterized through oxide

    chemical analysis, x-ray diffraction, Blaine fineness, laser particle size analysis, setting behavior, and

    strength measurements. Additionally, limited restrained shrinkage experiments were performed on two

    of the cements from the same source to determine the effect of cement fineness on restrained shrinkage.

    The findings indicate that cement fineness is better correlated to 7-day heat of hydration than the heat

    index expressed as C3S + 4.75 C3A. Additionally, the results indicate that a finer cement experiences

    higher shrinkage than a coarser cement. Comparison of activation energies indicates that cements with

    higher fineness have lower activation energy. For Type II moderate heat (MH) portland cements that

    will be used in structural concrete elements where there is a risk of cracking due to thermal stresses, it

    is recommended that limits be placed on the heat of hydration, the Blaine fineness, and the heat index.
