Abstract: The ultra-high strength concrete (UHSC) used in this study had a compressive strength greater than 145 MPa and was produced using materials commonly available in southern New Mexico. Specifically, locally available Type ...

Abstract: This paper presents the development of a new algorithm to identify dynamic properties of concrete by comparing simulated and experimental results of nonlinear ultrasound testing. Prismatic concrete specimens with different ...

Abstract: An experimental program consisting of resilient modulus and creep‐rebound testing was conducted to determine the effects of aggregate top size on the stiffness and resistance to permanent deformation of bituminous concrete ...

Abstract: A field study of corrosion of reinforcing bars in existing concrete pier structures is presented in this paper. The objective of the research was to evaluate the effectiveness of calcium nitrite for combating corrosion in ...

Abstract: A two-dimensional algorithm has been developed to determine the locations and sizes of steel bars in reinforced concrete members. This algorithm uses magnetostatic relationships to relate measured distortions in the magnetic ...

Abstract: Tests were conducted to measure the fundamental frequencies of reinforced concrete beams. Beams were tested prior to load application and after they had been loaded to various fractions of their ultimate moment capacity. ...

Abstract: Ultrahigh-performance concrete (UHPC) exhibits exceptional strength and durability properties that facilitate smaller, more efficient members that have longer expected lifespans compared to conventional concrete. However, ...
