Filter by Keyword7 report(s) found with mechanical properties in the keywords field 1 - 7 of 7 Calcium sulfoaluminate (CSA) cement was used to cast a prestressed voided deck slab bridge girder. The rapid-set properties of CSA cement allowed the initial concrete strength to reach the required 4300 psi needed in order to cut the prestressing strands 6.5 hours after casting. Prestress losses were... Accurate prediction of the shear strength of swelling clays is critical for the design of infrastructure. Damage caused to U.S. infrastructure by swelling clays is estimated to be about $13 billion per year. Overestimation of strength can lead to failures, and underestimation can lead to an increase... This study aims to investigate the age-dependent changes in flexural and fracture properties of fiber-reinforced concrete (FRC) used in the design of thin overlay pavements. Four different types of steel or polypropylene macro-fibers with different dimensions and different fiber volume contents (0%... Concrete infrastructures in cold areas such as South Dakota tend to experience early deterioration that is mostly triggered by steel corrosion. The corrosion is initiated by chloride penetration through cracks in the concrete. Fiber reinforced concrete (FRC) is known to be a good alternative to conventional... The objectives of this study were to assess geotechnical properties of mine waste amended with fly ash and evaluate reuse of fly ash amended mine waste as road construction material. Three types of fly ash and one type of cement were used as cementitious binder. Natural and synthetic (i.e., laboratory... Over the years, Fiber Reinforced Polymer (FRP) composites have gained popularity in transportation infrastructure as a material able to restore and increase the capacity of existing concrete elements. Properties such as a high strength to weight ratio, non-corrosive nature, durability, and high malleability... Untreated native soil with high swell potential has been identified by the Colorado Department of Transportation as one of the major contributing factors in the development of premature longitudinal cracking and other pavement distresses in Colorado (Ardani et al. 2003). Unique regional factors such... |
