This paper reports the results of an experimental investigation into the effects of incorporating varying amounts of expanded polystyrene beads on the engineering properties of high-strength concrete. It was observed that a density reduction of 8.3% caused compressive strength, tensile strength and modulus of elasticity to reduce by 48%, 39% and 15%, respectively. Drying shrinkage was marginall...

The objective of this research is to provide a new recycling method for one the most consumed plastics today, since it used manufacture wide variety industrial products, which leads an environmental problem caused by incorrect handling and final disposal. dissolution expanded polystyrene waste was evaluated using natural esters its post treatment recovery. use omega-3 as solvent creates opportu...

The aromatic rings of polystyrene (PS) were hydrogenated in decahydronaphthalene (DHN) expanded with supercritical carbon dioxide (scCO2). Conducting the hydrogenation in scCO2-DHN offers the benefits of improved transport properties, specifically lower solution viscosity and a higher PS diffusion coefficient. Various Pd catalysts are effective for hydrogenating the aromatic rings of PS at temp...
