RISCombined Free and Forced Convection Through Vertical Rectangular Channels With Unequal Heating From Sides
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fully developed laminar combined free and forced convection through vertical rectangular channels is studied. Uniform heat input per unit length is considered. All fluid properties are considered ...
HPC Composites Formulated to Counteract Early ASR Expansion
Publisher: American Society of Civil Engineers
Abstract: The authors investigated the ability of different high-performance concrete (HPC) composites to restrain an alkali-silica reaction (ASR) in the presence of reactive aggregates. They evaluated the effectiveness of different ...
Optimized Fresh and Hardened Properties of Strain Hardening Cementitious Composites: Effect of Mineral Admixtures, Cementitious Composition, Size, and Type of Aggregates
Publisher: American Society of Civil Engineers
Abstract: The present paper thoroughly investigates the effects of mix design with various water-to-binder (W/B) ratios, types of mineral admixture and types and sizes of local sands on the tensile ductility of engineered cementitious ...
Fiber-Matrix Interfacial Behavior of Hooked-End Steel Fiber-Reinforced Concrete
Publisher: American Society of Civil Engineers
Abstract: Concrete has inherent low tensile strength and fails at low tensile strains. These drawbacks have been bypassed by the introduction of discontinuous randomly distributed fibers to the concrete. The fiber-matrix interfacial ...
Forced Convective Heat Transfer in Cross-Corrugated Solar Air Heaters
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Forced convective heat transfer in a cross-corrugated channel solar air heater has been studied experimentally using air as a working fluid. The channel was formed by two transversely positioned ...
Optimized Fresh and Hardened Properties of Strain-Hardening Cementitious Composites: Effect of Sand Size and Workability
Publisher: American Society of Civil Engineers
Determination of Temperature Dependence of Electrical Conductivity and Its Relationship with Ionic Strength of Anaerobic Digester Supernatant, for Struvite Formation
Publisher: American Society of Civil Engineers
Abstract: Electrical conductivity (EC) is used for monitoring different types of aqueous systems. The measured EC value at any temperature needs to be corrected for a standard temperature, for reporting or comparison, since EC is ...
Viscous Dissipation Effects on Combined Free and Forced Convection Through Vertical Circular Tubes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of viscous dissipation on the flow phenomena and heat transfer rate in a vertical circular duct is analyzed for combined free and forced convection. All fluid properties are considered ...
Production of Recycled Plastic Aggregates and Its Utilization in Concrete
Publisher: American Society of Civil Engineers
Abstract: Plastic represents an environmental issue, as only 7% of it is recycled. The plastic remaining is either burned, disposed of in an uncontrolled manner, or landfilled. Thus, to reduce the quantity of plastic that is disposed ...
Constitutive Compressive Stress–Strain Behavior of Hybrid Steel-PVA High-Performance Fiber-Reinforced Concrete
Publisher: ASCE
Abstract: The constitutive compressive stress–strain response of hybrid high-performance, fiber-reinforced concrete (HyHP-FRC) containing steel and polyvinyl alcohol (PVA) fibers is scarcely reported. In this study, the compressive ...
