Abstract:
This paper presents a summary of six years of concrete control data for the Friant-Kurt canal and distribution systems for the Bureau of Reclaimation's Central Valley Project in California. The period covered is from June, 1946, to June, 1952. Several relationships between the different qualities of the concrete have been plotted, disclosing both an over-all trend and a cyclic variation. Partial explanation has been made for the trends and cycles, but some of the causes are obscure and defy identification.
