Performance of concrete sidewalks: field studies
This article examines the different failure modes of concrete sidewalks through an extensive field survey of sidewalk inventories in major cities in the Canadian Prairies. The major form of sidewalk damage is longitudinal cracks. There was no correlation of either the liquid limit or the plastic limit of the soil beneath the sidewalk with the type of sidewalk damage observed in each city. Howev...
متن کاملIndirect estimates of flexural strain in concrete sidewalks induced by vertical movement
This paper examines different numerical methods to estimate flexural strain from surface elevation measurements on concrete sidewalks. Surface elevations, along a typical concrete sidewalk cross section, were monitored on a monthly basis as part of a study to determine the cracking mechanism of concrete sidewalks. These measurements were carried out in Calgary, Edmonton, and Camrose, Alberta, b...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Field Performance of Prestressed High Performance Concrete Highway Bridges in Texas
16. Abstract Two prestressed high performance concrete (HPC) highway bridges were constructed in Texas utilizing concrete with 56 day design strengths of up to 97 MPa (14,000 psi). The utilization of HPC allowed for longer spans and larger girder spacing than typically used in conventional prestressed concrete bridges. An extensive research program was conducted to monitor the shortand long-ter...
متن کاملPerformance of High-strength Concrete
This research was undertaken to investigate performance of high-strength concrete incorporating mineral admixtures, fly ash and silica fume. For modern construction, the use of new construction materials is increasing to achieve economy and improved final results. An extensive literature search was carried out to review various engineering properties of high-strength concrete. In this study, th...
