The present invention relates to settable compositions for general purpose concrete construction containing Class-F fly ash, Class-C fly ash or slag, and potassium sulfate (K2SO4) as a substantial replacement for Portland cement conventionally used in such compositions. The potassium sulfate is an additive for improved high early strength and accelerated setting times, thereby allowing the concrete structure to be put into service sooner, reducing labor cost, and allowing precast concrete and concrete masonry manufacturers to achieve rapid form and mold turnover.
