Workability Assessment of Pumpable Structural-Grade Heavy-Weight Concrete Using Novel Coaxial Cylinder Method
(American Society of Civil Engineers, 2023/07/01)The mixture proportioning of heavy-weight concrete (HWC), as seen from the literature, is primarily based on a trial-and-error approach; even so, data from the literature indicate that obtaining high-slump mixtures for ... -
Tearing Property and Allowable Tearing Stress of PVC-Coated Polyester Fabric Membranes at High Temperature
(American Society of Civil Engineers, 2023/06/01)PVC-coated polyester fabric is a widely used building material whose tearing strength is much lower than its tensile strength. Extreme loads such as fire, unexpected winds, or hail may cause cracks in the membrane. The ... -
Effect of the Chemical Nature of Polyvinyl Alcohol on the Microstructure of Cement Hydration Products
(American Society of Civil Engineers, 2023/07/01)The influence of chemical nature of polyvinyl alcohol (PVA) on the microstructure of cement hydration products was investigated. Thermal analysis, X-ray diffraction, Si29 nuclear magnetic resonance (NMR), and scanning ... -
Strength Characteristics of Geopolymer Synthetic Sand Using Fly Ash
(American Society of Civil Engineers, 2023/06/01)Sand is a naturally available resource that has numerous applications in civil engineering. Due to a rapid increase in construction activities and exploitation of natural resources, there has been a scarcity of natural ... -
Evaluating the Impact of Crushing Process on Strength Characteristics and Leachability of Cement-Stabilized Dredged Sediment
(American Society of Civil Engineers, 2023/06/01)Stabilization of dredged sediment and reusing the mixture as a construction material is an effective way to reduce environmental problems and save natural resources. However, the crushing process that occurs during ... -
Long-Term Corrosion Monitoring of Bacterially Healed Concrete Using Electrochemical and Ultrasonic Techniques
(American Society of Civil Engineers, 2023/07/01)Bacterial biocementation has been shown to have the unique capability of healing cracks in concrete. However, there is a concern that the materials used in biocement may cause corrosion. This paper reports the performance ... -
