RISInfluence of Clinker Replacement and Curing Temperature on Hydration Kinetics, Strength Development, and Phase Assemblage of Fly Ash–Blended Cements
Publisher: ASCE
Abstract: The influence of clinker replacement on temperature sensitivity of fly ash–blended cements was investigated at three realistic temperatures. Blends were prepared by replacing clinker with fly ash or quartz at two replacement ...
Graphical Facial Expression Analysis and Design Method: An Approach to Determine Humanoid Skin Deformation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The architecture of human face is complex consisting of 268 voluntary muscles that perform coordinated action to create real-time facial expression. In order to replicate facial expression on ...
Effect of Perforation on Vortex Characteristics of a Microvortex Generator Mounted on a Flat Plate
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effects of perforation on the characteristics of the downstream vortex of a microvortex generator (MVG) mounted on a flat plate, are numerically investigated in this paper. A single rectangular MVG with circular and ...
Understanding the Influence of Thermal Treatment on Phase Changes and Reactivity of Smectite for Use in Limestone Calcined Clay Cement
Publisher: American Society of Civil Engineers
Abstract: AbstractThe partial replacement of cement by calcined clays is seen as one of the most important
avenues for producing low-carbon cements. However, the limited availability of kaolinite
may become a major barrier for the ...
Impact of Alkali Salts on the Hydration of Ordinary Portland Cement and Limestone–Calcined Clay Cement
Publisher: ASCE
Abstract: Soluble alkalis play a vital role during early age hydration and strength development in cement. This study investigates the influence of alkali addition on the hydration, phase assemblage, and strength development in ...
Modeling the Variation in Hydration and Strength of Blended Cement–Fly Ash Systems
Publisher: ASCE
Abstract: Variations in the properties of fly ashes from various sources can lead to large variations in the performance of fly ash–blended cement systems. The current study combines analytical and numerical modeling approaches to ...
MDOF Modeling and Blast Dynamic Behavior of Curtain Wall with Variable Damping Approach
Publisher: ASCE
Abstract: In the present paper, a semi-active damping control approach is proposed for the resilient design of façades subjected to extreme loads in the form of blast excitation. A 4 degrees of freedom (4DOF) model is developed ...
Detached Eddy Simulation of Micro-Vortex Generators Mounted on NACA 4412 Airfoil
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Micro-vortex generators (MVGs) are simple vane-type devices installed on surfaces , i.e., aircraft wing and tail, to control boundary layer flow separation. They are cost-effective and require an efficient numerical method ...
Probabilistic Characterization of Nuclear-Blast Loads
Publisher: ASCE
Abstract: With increasing stockpiles of nuclear warheads, it has become essential to fortify critical infrastructure against nuclear blast. Therefore, a reliable estimation of nuclear-blast load is crucial for design of such hardened ...
