Available in PDF, EPUB and Kindle. Book excerpt: At Lost Creek Dam at Trail, Oregon, lean 3-inch maximum size aggregate (MSA) concrete mixtures were designed to be compacted by vibratory rollers. The control mix contained 235 pounds cement per cubic yard while other mixtures had a portion of the total volume of cement replaced with pozzolan, either fly ash or a locally available calcined shale. Each layer, except bedding layers, was approximately 8-inches thick after compaction. Laboratory work on control testing was conducted. It was concluded that properly proportioned roller compacted concrete can be effectively placed by soils compaction methods using a vibratory roller. The results of tests on drilled core specimens indicate that permeability and bond test results are similar to conventionally placed lean mass concrete values. The quality of the hardened lift joint is improved with the use of bedding mixtures. A modified Vebe apparatus can be used for control testing and for molding concrete central cylinders.

Book excerpt: The subjects of the symposia are on composite materials with matrices behaving as brittle in normal or special conditions. Brittle matrix composites are applied in various domains (civil engineering, mechanical equipment and machinery, vehicles, etc.) and in the last decades their importance is increasing together with their variety. Papers include: aggregate-binder composites (concretes, fibre concretes, rocks); sintered materials (ceramics); high strength composites with brittle matrices. In principle, the general problems of structures made of composite materials are not included in the papers. Various approaches to the material engineering problems are presented in the papers.

This book was released on 1998 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ths report documents the results from a laboratory mechanical property investigation of large-diameter, roller-compacted concrete (RCC) core samples obtained from the main Elk Creek Dam, Trail, Oregon. The test matrix included 10 unconfined compression tests, 13 unconfined tension (direct pull) tests, 8 triaxial compression tests, 16 direct shear tests, and 7 splitting tensile strength tests. Eight of the direct shear tests and six of the unconfined tension tests were performed for the purpose of characterizing the strength properties of the interfaces between the RCC lifts. All tests were performed quasi-statically on air-dry specimens of the RCC. In addition, an extensive suite of nondestructive pulse velocity tests were performed on the cores to assess the degree of anisotropy in the RCC. This included numerous P-(compression), Sa-(shear waves vibrating in the axial plane), and Sr-(shear waves vibrating in a radial or cross-axis plane) wave speed determinations measured radially through the core with propagation directions oriented 0, 45, 90, and 135 deg from the right-abutment side of the dam core. Axial P- and Sa-wave velocities were determined for each mechanical property test specimen prior to being mechanically deformed.

Available in PDF, EPUB and Kindle. Book excerpt: During the life of a dam, changes in safety standards, legislation and land use will inevitably occur, and functional deterioration may also appear. To meet these challenges, these Proceedings from a panel of international experts assess, define and re-evaluate the design criteria for the construction of dams and the many attendant issues in on-going maintenance and management. Authors include international specialists: academics, professionals and those in local government, utilities and suppliers. Practitioners from these same fields will find the book a useful tool in acquiring a comprehensive knowledge of managing and retrofitting dams, so that they can continue to meet society's needs.
