Lightweight alkali-activated materials and ordinary Portland cement composites using recycled polyvinyl chloride and waste glass aggregates to fully replace natural sand
Abstract: Polyvinyl chloride plastic (PVC) and glass waste have proven to be significant environmental concerns considering their restricted reuse and complicated recycling procedures. Glass and PVC...
An Experimental Study on Thermophysical Parameters of Production Wells and their Applications
Abstract: Transient pressure and temperature behavior in a wellbore develops as hot fluids from the reservoir move upward, exchanging heat with the surrounding formation. Because of heat exchange...
Experimental investigation of the effect of thermal cycling on the thermomechanical properties of three rock varieties for high temperature thermal energy storage
Abstract: During the past years "rock batteries" have become increasingly relevant for the storage of renewable energy sources, such as wind and solar energy, because of their economic and ecological...
Evaluating thermal conductivity of desert sand under different initial physical properties
Abstract: Analyzing the thermal conductivity of soil as a function of other parameters is necessary to understand the flow of heat around earth-to-water heat exchanger. Thermal conductivity depends...
Results from the GeoERA MUSE shallow geothermal project – UK Cardiff pilot area
Abstract: Shallow geothermal energy systems deployment will play an important part in decarbonisation of heating and cooling of buildings. This trend will stimulate research into ground physical,...
High frictional stability of braking material reinforced by Basalt fibers
Abstract: Frictional stability is a more accurate description of the friction state than coefficient of friction (COF) and wear rate. This work aims to develop basalt fiber (BF)-reinforced braking...
Glass-ceramic foams produced from zeolite-poor rock (Tokaj)
Abstract: This study evaluated the possibility of producing innovative glass-ceramic foams from zeolite-poor rock (Tokaj, Hungary) using alkali-activation and reactive sintering techniques. The...
3D printing of cordierite materials from raw reactive mixtures
Abstract: Porous cordierite materials are 3D printed by robocasting from two kaolin containing raw materials mixtures. Water suspensions of both mixtures at variable solid concentrations...
DEVELOPMENT AND THERMO-MECHANICAL BEHAVIOR OF CEMENT-BASED COMPOSITE FOR THE RUNWAY CONCRETE OF F-35B JOINT STRIKE FIGHTER
Abstract: The current study aims at increasing the strength and heat resistance of concrete that can be used in airport pavements for vertical take-off and landing of new generation F-35B combat...
