Eighth Joint Meeting on Hydrotechnical Concrete

Abstract

the construction site of the Inguri hydroelectric project and was devoted to the topic "Acceleration of methods of quality control of hydrotechnical concrete." The conference was attended by more than 70 representatives of 37 planning, research, and construction organizations and of institutes of higher learning of the country, 25 reports were presented. The opening address of Doctor of Technical Sciences Prof. V. V. Stol'nikov was devoted to a review of current accelerated methods of concrete quality control and to the task of the conference.The increased level of demands placed on the concrete of dams and the diversity of concrete characteristics which require daily control were pointed out. Many standard characteristics (maximum tension, impermeability, shrinkage, swelling) have been introduced for the first time into the new State Standard GOST 4795-67. The most important requirements imposed on newly proposed accelerated methods of control should be: a) simplicity and flexibility of the methods of accelerated determinations; b) possibility of statistical analysis of the results; c) reliability of the determinations themselves and reproducibility of the obtained results.
