Filter by Keyword50 report(s) found with materials in the keywords field Fibers are used in an asphalt mix to improve its durability and resistance against distresses, such as rutting and cracking. Consequently, accurate rheological and performance characterization of asphalt binders and mixes containing fibers is of vital importance. With increased concerns over the environmental... Escherichia coli (E. coli) is often used as an indicator organism to quantify the microbial safety of natural water resources. E. coli in stormwater runoff can cause serious health risks in natural water bodies. Conventional stormwater best management practices are generally not effective at removing... This report presents the behavior of reinforced concrete beams retrofitted with carbon fiber reinforced polymer (CFRP) sheets and ultra-high performance concrete (UHPC) jackets in a multi-hazard environment. Following the procedural protocol of a published standard, the beams are cyclically loaded under... In recent years, major initiatives have been taken to replace non-renewable materials with environmentally friendly and sustainable ones. The present study was undertaken to apply a scalable process for laboratory production of cellulose nanofibers (CNF) and to evaluate the feasibility of using the produced... Ultra-high-performance concrete (UHPC) is distinguished by its superior mechanical and durability properties. These characteristics are attained through a precise mixture design that includes a low water-to-cement ratio, high fineness supplementary cementitious materials (SCMs), and steel fibers. This... With the popularization of accelerated bridge construction (ABC), the utilization of splice sleeve connections has been researched to determine their performance using a variety of connection details and under several loading scenarios. However, fundamental research on the load distribution and load... This research explores the influence of thermo-mechanical beneficiation methods on the physicochemical characteristics and reactivity of fly ashes disposed of in landfills (LFAs) obtained from power plants in Wyoming and Colorado, USA. An in-depth assessment was conducted on the mechanical and performance... The first part of the study presents the time-dependent interfacial behavior of near-surface-mounted (NSM) carbon fiber reinforced polymer (CFRP) strips bonded to a concrete substrate using inorganic resins. Four types of bonding agents (mortar, polyester-silica, ultra-high performance concrete (UHPC)... Stormwater runoff generated in urban areas can increase the risks of flooding and contaminate surface waters. Various contaminants carried by stormwater runoff can negatively affect the water quality of receiving water bodies. Many of the conventional stormwater best management practices are designed... This report presents a comparative experimental study on the axial behavior of concrete subjected to alkali-silica reaction (ASR) with and without confinement by carbon-fiber reinforced polymer (CFRP) sheets. A total of 120 cylinders are cast using two types of coarse aggregates to represent variable... |
