Surface seeded aggregate and method of forming the same

Abstract

An improved method of producing surface seeded exposed aggregate concrete upon a subgrade. The method comprises the initial step of pouring a concrete mixture over the subgrade, which is followed by the step of finishing the exposed surface defined by the concrete mixture with a vibrating metal bull float to dispose a quantity of cement/fines paste derived from the concrete mixture at the exposed surface thereof. Thereafter, a quantity of aggregate is broadcast upon the exposed surface of the concrete mixture and subsequently mixed into the quantity of cement/fines paste thereof via the vibrating metal bull float. The exposed surface of the concrete mixture is then finished with a power trowel to facilitate an even distribution of the quantity of aggregate within the quantity of cement/fines paste, which is followed by the application of a surface retarder to the exposed surface of the concrete mixture. The exposed surface of the concrete mixture is then finished with the power trowel to massage the surface retarder into the quantity of cement/fines paste having the quantity of aggregate mixed therein.
