Lightweight fill can be advantageous in embankment construction for the purposes of reducing (i) bearing pressures on underlying soil foundation, (ii) destabilizing moments constructed earthen slopes, and (iii) earth acting behind retaining walls. This paper investigates merits/limitations particulate expanded polystyrene (EPS) beads mixed with clayey sand (CS) as lightweight fill, considering ...

By incorporating lightweight expanded polystyrene aggregate particles in a conventional highstrength concrete mixture, its density could be adjusted to any desired level. The adjusted density concrete can be expected to have reduced strength and stiffness the permeability of concrete would not be affected since the non-water absorbing polystyrene aggregate particles are dispersed randomly in a ...

Granular jamming has been identified as a fundamental mechanism for the operation of robotic grippers. In this work, we show, that soft particles like expanded polystyrene beads lead to significantly larger gripping forces in comparison rigid particles. contradiction naive expectation, combination and elasticity gives rise very different properties jammed phase, compared hard-particle systems. ...

The peak particle size and expanded uncertainties (95 % confidence interval) for two new particle calibration standards are measured as 101.8 nm ± 1.1 nm and 60.39 nm ± 0.63 nm. The particle samples are polystyrene spheres suspended in filtered, deionized water at a mass fraction of about 0.5 %. The size distribution measurements of aerosolized particles are made using a differential mobility a...

The disposal of massive amounts waste, particularly nondecaying is now a major issue for both developed and developing countries. One the most sustainable solutions to this problem recycle garbage into valuable items. Expanded polystyrene, which manufactured in large quantities, one these waste materials. This being used globally as packaging material, construction household appliances. expande...

polymer/clay nanocomposites are considered as a new subject of research in iran and the world. addition of a minimum amount of clay (2-5wt%) can improve the mechanical properties, enhance barrier properties and reduce flammability dramatically. polystyrene (ps) exhibits high strength, high modulus and excellent dimensional stability, but it has poor ductility, elongation, and flexural modulus. ...
