Title: “Mass Concrete Mixture Development for Thermal Control”

Specifications for mass concrete often require explicit planning and control of thermal stresses. Historically, overdesign of compressive strength and usage of extremely high portland cement contents has caused varying degrees of early age cracking due to both thermal and autogenous shrinkage stresses in buildings and bridges. Development of low heat performance concrete or LHPC will help to minimize cracking and improve service life by meeting multiple performance objectives.  A properly designed LHPC can ease thermal control requirements and save time in the schedule, as well as provide a higher level of durability to owners. Design of LHPC requires minimization of cementitious materials content, optimization of supplementary cementing materials (SCMs), uniform gradation of aggregates, and selection of advanced admixture technology. A performance engineering approach incorporates durability in addition to early strength and constructability requirements to meet contractor needs. Performance requirements can include restrained shrinkage cracking resistance, linear free shrinkage limits, freeze-thaw resistance, alkali-silica reactivity, and chloride penetration resistance. Field performance to date has indicated that LHPC will provide owners with an increase in service life while meeting mass concrete specification requirements.
