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 potassium chloride (KCl) as a substantial replacement for Portland cement conventionally used in such compositions. The potassium 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.
Claims50
A settable composition comprising at least about 50 percent cement and about 1 percent to about 5 percent potassium chloride, wherein all percentages are based on the total weight of the composition.
A settable composition comprising cement, Class-F fly ash, and potassium chloride, wherein the potassium chloride is present in an amount of about 1 percent to about 5 percent by weight based on the total weight of the settable composition.
A settable composition comprising cement, Class-C fly ash, and potassium chloride.
A settable composition comprising cement, Class-C fly ash, Class-F fly ash, and potassium chloride.
A settable composition comprising cement, slag, and potassium chloride, wherein the potassium chloride is present in an amount of about 1 percent to about 5 percent by weight based on the total weight of the settable composition.
