G561: Coating & Repairing Materials For Concrete Hydraulic Structures Damaged By Erosion

The objectives of this project were to review and select the most suitable materials, existing as well as under development, for repairing concrete hydraulic structures damaged by erosion. The materials selected were cementitious grouts, polymer modified cement based mortars containing acrylics, styrene butadiene rubbers or copolymers and epoxy mortars.

G944: Use of High Volumes of Fly Ash in Grouts and Shotcrete for Applications in Hydraulic Structures

This project involved the study of using high-volume fly ash (HVAF) in grouts and shotcrete for applications in hydraulic structures. The main objectives of this project were:a) to develop HVFA cementitious grouts and shotcrete with and without silica fume for repair and rehabilitation of hydraulic structures;b) to determine long-term durability aspects of HVFA concrete covering carbonation and corrosion of reinforcing steel embedded in HVFA concrete when exposed to NaCl solution. The report co

G788: Soniscope - Enhanced Capabilities

The objective of this project is to attempt to evaluate the capabilities of the redeveloped Soniscope (CEA Project 427 G 519). An extensive review of the literature on ultrasonic pulse velocity testing through concrete together with a limited laboratory testing program was undertaken to evaluate the properties and capabilities of the instrument.

G815Phase IV: Static Ice Loads on Hydro-Electric Structures: Field Measurements Made at the Arnprior and Otto Holden Dams During the 1994-95 Winter: Data Report

This report presents field data that have been collected as part of Phase IV of a project that was undertaken to improve present understanding of ice loads on hydro-electric structures. A more detailed analysis of these data, and of other data sets, will be included as part of this project, and these analyses will be reported under separate cover. Field data were collected during the 1994-95 winter at Ontario Hydro's Arnprior and Otto Holden dams.

G632: Survey and Evaluation of Instruments and Systems For Telemetering Data For Dams

The main objective of this research was to review and evaluate the situation of remotely controlled instruments and automated transmission for dam monitoring in Canadian conditions. This would be beneficial to utilities concerned with safety and performance of existing hydraulic structures.

G641: Simulation of Dam Break Surges For The Erosion Effects: Technical Volumes I+II and Appendices

The objectives of the project are to produce a numerical model of dam break surge simulation (whereby the sediment erosion, transport, and deposition phenomena are included) suitable for use on a personal computer; and to investigate the effects of ice on the hydrodynamics and sediment transport regime. A number of hydrodynamic and sediment transport models were examined. The study included a comprehensive literature review and examination of presently available methodologies and models. Analyse

G687: Expansion Test Methods For Mass Concrete Exposed To Alkali Aggregate Reaction Volume I+II Pricing For Set of 2 Volumes

'The main objective of this study was to propose modifications to the existing test methods in order to better stimulate field performance of mass concrete exposed to alkali-aggregate reactivity. Two non reactive aggregates and nine others thought to be alkali-reactive in dams were investigated through expansion tests on three different concretes: 1) CSA concrete made in accordance with the CAN/CSA A23.2-14A method, using a fixed water/cement; 2) "CSA+" concrete, using a higher cement content; a

G2015: Static Ice Loads on Hydro-Electric Structures: Field Measurements Made at the Seven Sisters Generating Station During the 1995-1996 Winter - Data Report

This report presents field data that have been collected as part of Phase V of a project that was undertaken to improve present understanding of ice loads on hydro-electric structures. Field data were collected during the 1995-96 winter at Manitoba Hydro's Seven Sisters Generating Station to measure the ice stresses and loads:(a) in the reservoir ice sheet, and:(b) in front of a pier, a wooden stoplog section, and a steel stoplog section.As well, the ice temperature profile was measured along w

G758: Field Application of Coatings to Protect Concrete Hydraulic Structures from Cavitation Damages

The main purpose of this project was to determine the effectiveness of polymeric coatings to protect concrete hydraulic structures from erosion due to cavitation. A screening test using a cavitating jet nozzle was performed in the laboratory to identify cavitation resistant materials. Subsequent testing was performed on the candidate materials to ensure that they can be successfully applied onto concrete. Testing included determining the bond strengths of the coatings to the concrete, and to per

EG910012/1: Static Ice Loads on Hydro-Electric Structures: Environmental and Probabilistic Analysis of Thermal Loads

An environmental model has been developed in this project to predict the ice thickness, the snow cover thickness, the slush thickness, and the ice temperature profile area as a function of time over the winter for a reservoir ice sheet. The ice temperature profile area is one of the essential inputs to a predictor developed previously for thermal ice loads. The environmental model was compared against the field data measured at the Paugan, Arnprior, Otto Holdenm, and Seven Sisters dams. Hind-cas
