Title: Use of Prepacked Aggregate Concrete in Major Dam Construction

Keywords: no keywords
Abstract:This paper sets forth the method of construction of a major gravity dam whereby the average temperature of the mass concrete may be controlled within the mean annual and the dry shrinkage reduced to a fraction of that of conventional concrete by means of prepackaging of the coarse aggregate to a density corresponding to 30 percent voids; precooling the aggregate; the intrucsion of the coarse aggregate by mortar with a cement content of two sacks per cu yd or less; and the internal post-cooling, curing and draining of the mass concrete. (This process is known as the Prepakt method of construction.)
