Results of Field Investigations of the Quality of Jointing Precast Elements of Saratov Hydroelectric Powerplant (Rezultaty Naturnykh Issledovanii Kachestva Omonolichivaniya Stykov Sbornykh Elementov Saratovskoi Ges)
Saratov combined dam and powerplant on the Volga is built from an experimental design, using precast reinforced concrete elements. The separate elements are jointed by placing and vibrating concrete mix in 60-cm-wide joints, following a technology developed by research institutes. Field tests on these joints during 1965 showed that, with proper technology and equipment, the bond between the concretes of the element and the joint and the density, strength, and watertightness of joint concrete were satisfactory. However, many unsatisfactory joints were found, due to failure to place all concrete in the joint continuously, failure to meet mix specifications, and poor vibration for lack of proper vibrating equipment. The methods used and results of these field tests are discussed. (Author)
