Quality control of concrete

This report presents a general review of systems, practices, methods of testing, and other considerations that underlie the quality control of concrete production during the construction of large dams. The main purpose of this report is to assemble available information and experience into a concise guide for the preparation of a quality control program for the construction of a concrete dam and its appurtenant works.

The emphasis of this report is the quality control of mass concrete produced for placement in massive blocks in the body of a dam. However, most of the practices and methods are also valid for quality control of concrete production for related structures such as spillways, aprons, powerhouses, piers, etc. detailed quality control practices for placing, compacting, and curing of concrete during dam construction are not considered within the scope of this report.
