Abstract
The present invention relates to settable compositions for general purpose concrete construction containing Class-F fly ash, Class-C fly ash or slag, and sodium chloride (NaCl) as a substantial replacement for Portland cement conventionally used in such compositions. The sodium chloride 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.
