Flexural performance of textile fine grained mortar containing risk husk ash as a partial cement replacement in reinforced concrete beams
… % and 40% was investigated under compressive and flexural strength. Optimum replacement of RHA in FGM also determined. 20 % of RHA replacement in cement consumption of FGM gave excellent of compressive and flexural strength. Utilization of 20 % RHA in FGM was continuing to use when FGM combined …

Increasing residual structural capacity of cracked concrete railroad crossties with polypropylene fibers
… the concrete has cracked. The center negative flexural cracking is considered as a serious failure mode in concrete railroad crossties, which decreases structural capacity and results in safety issues. It also leads to deterioration of prestressed concrete crossties and shortens the service …

Flexural Behavior of Cold-Formed and Hot-Rolled Steel Sheet Piling Subjected to Simulated Soil Pressure
… piling has long-been believed to have a better flexural performance than cold-formed sheet piling based on a test conducted by Hartman Engineering twenty years ago. However, cold-formed steel can have similar strength to the hot-rolled steel This experimental program studied the flexural …

Aging of a Polymer Core Composite Conductor Under Combined Ozone and Temperature Conditions
… room temperature did not negatively affect the flexural performance of either the neat resin epoxy, or the hybrid composite rods. When aged up to a year at 140°C no detrimental effect on flexural performance of the composite was observed, as opposed to aging at 180°C, which had a very negative …

Analysis of the design of railroad track superstructure components for rail transit applications
An extensive study of the performance of railroad superstructure in rail transit systems was conducted at the University of Illinois at Urbana-Champaign (UIUC) as part of a research program funded by the Federal Transit Administration (FTA). Focusing on field characterization of the performance of …

The Effect of Atmospheric Aging on a Hybrid Polymer Matrix Composites' Material Properties
… in this research. In particular, the flexural performance (in both static and fatigue loading) of the composite which had been exposed to elevated temperatures for prolonged periods of time was studied. To this end, a fatigue test was developed in an attempt to simulate the multi-axial …

Performance Evaluation of RC Flexural Elements Strengthened by Advanced Composites
The flexural performance of composite systems made of reinforced concrete, Fibre Reinforced Polymers (FRPs) and adhesives was studied during the current research. The experimental investigation was principally concentrated on the potential use of Kevlar® 49 (aramid fibre) for RC beam strengthening. …
