Abstract: A salt-saturated concrete proportioned with Class H oilwell cement, Class F fly ash, and a shrinkage compensating component was developed to meet performance requirements for mass placement as seal components at the Waste Isolation Pilot Plant. Target properties of the concrete included 8-in. slump 3 hr after mixing, no aggregate segregation, heat rise of < 25°F 4 hr after mixing, compressive strength of 4,500 psi at 180 days, minimal volume change, and probable geochemical stability for repository conditions. Thermal and mechanical properties of promising candidate concrete mixtures were measured. Modulus of elasticity and creep behavior were similar to those of ordinary portland cement mass concretes. Thermal expansion for the salt-saturated concrete developed here was typical of ordinary concrete with similar silicate aggregates. Thermal conductivity, diffusivity, and specific heat approximated values measured for other mass concretes and were similar to values of the host salt rock.
