Pertinent physical properties of three mass concrete mixtures were determined and used as input to finite-element programs to calculate temperature rise and resulting thermal strains in mass concrete. This concrete mixture proportioned with coarse aggregate having an elastic modulus of 7,800,000 psi produced 1.3 times higher creep and 1.5 times greater increase in ultimate strain capacity, with lower modulus of elasticity, than did concrete with a coarse aggregate with a modulus of 11,000,000 psi. Concrete mixtures tested produced values for adiabatic temperature rise between 39 F for 3000-psi concrete with 25 percent pozzolan replacement and 85 F for 4000-psi with no pozzolan.
