Production technology and properties of polystyrene concrete on recycled polystyrene

Seismic Performance of Composite Shear Walls Constructed Using Recycled Aggregate Concrete and Different Expandable Polystyrene Configurations

The seismic performance of recycled aggregate concrete (RAC) composite shear walls with different expandable polystyrene (EPS) configurations was investigated. Six concrete shear walls were designed and tested under cyclic loading to evaluate the effect of fine RAC in designing earthquake-resistant structures. Three of the six specimens were used to construct mid-rise walls with a shear-span ra...

Effect of Styrene Maleic Anhydride on Physical and Mechanical Properties of Recycled Polystyrene Wood Flour Composites

In this work, the influence of three types of styrene maleic anhydride (SMA) oligomers on the adhesion of polystyrene wood plastic composites (WPC) was investigated. The composites were processed on a twin-screw co-rotating extruder below 200°C using 20 wt% of wood flour. The styrene maleic anhydride with different content of maleic anhydride groups, 30%, 25% and 20% (w/w) and levels of 1, 2 an...

Morphology and Properties of Wood. Fiber Reinforced Blends of Recycled Polystyrene and Polyethylene

ABSrRAcr: Material properties of composites prOOuced from ruycled plastics and ruycled ~ fiber were compared. A blend of high -density polyethylene aIKi polystyrene was used as a simulated mixed plastic. Stift'ness was generally improved by the addition of fiber, as expected, but brittleness also increased. Pre-treatment of the ~ fiUer with phenol-fonna1~ resins did not significantly a~t materi...

Effects of Recycled Concrete Aggregates on Properties of Asphalt Concrete

effects of different types of clays and maleic anhydride modified polystyrene on polystyrene/clay nanocomposites

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. ...
