Abstract: The microstructure of recycled aggregate prepared from the crushing of old concrete was studied. It was found that the recycled aggregate is covered with loose particles that may prevent good bonding between the new cement ...

Abstract: This study investigated the mechanism of stress transfer between glass and carbon fiber-reinforced polymer (FRP) laminates and concrete beams with deteriorated surfaces. Thirty-six beams were prepared with either a solid ...

Abstract: The environmental load of fiber-reinforced polymer (FRP) reinforced pavement was compared with that of steel reinforced pavement. Replacing steel rebars with FRP rebars can lead to changes in the concrete mix and pavement ...

Abstract: The bond mechanism of fiber-reinforced polymer (FRP) rebars to concrete was studied to evaluate the effect of cyclic loading. Five different types of 12.0- and 12.7-mm rebars were tested. The FRP rods were embedded in ...

Abstract: Winding helical fiber around fiber reinforced plastic (FRP) rods, which serve as concrete reinforcement, is used to enhance the bond between the rod and the concrete. A theoretical analysis of the strain development in the ...

Abstract: Thermal conductivity measurements are based on temperature gradients within the tested material. When testing nonsaturated moist porous materials, this gradient causes redistribution of the enclosed moisture and, as a ...

Abstract: This paper presents an analytic model, which describes the bridging load and fiber stress developed when an inclined brittle fiber bridges a crack. The coupled effect of fiber bending and axial loading is explicitly accounted ...

Abstract: The interfacial bond properties of two carbon fibers, having diameters of 10 μm and 46 μm, were tested for cement matrices of different water-to-binder (

Abstract: The level of thermal noise in a resonant vibrating beam gyroscope is lower, the longer the beam. A limitation on the length of the beam arises from the consideration that the beam acts as ...
