This work presents an experimental and theoretical study on the punching shear behavior of Lightweight Concrete Slabs. obtained using Expanded polystyrene (EPS) beads as partial coarse aggregate’s replacement, without adding supplementary bonding additives, to reduce concrete density from 2400 1800 kg/m 3 . The EPS content, strength column aspect ratio were test parameters. Five groups prepared...

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 ...

Abstract Changing material into a lightweight geomaterial such as EPSCS is one of the considerable methods to improve geotechnical performance in field. This already used numerous construction projects due its light characteristics. Lightweight Modular Block or LMB type composed dredged Soil, cement, and Expanded Polystyrene (EPS). The amount cement composition are 3%, 5%,7% 9%. Meanwhile, (EPS...

This research aims to create lightweight concrete mixtures containing waste from local sources, such as expanded polystyrene (EPS) beads and plastic fibers (WPFs), all are cheap or free in the Republic of Iraq without charge. The modern, rigid, mechanical properties LWC were investigated, results evaluated. Three made, each with different proportions (0.4%, 0.8%, 1.2%), addition a mixture steak...

To explore the cushioning properties of expanded polystyrene (EPS), a novel two-degree-of-freedom mathematical model is proposed with dynamic nonlinear system and successfully implemented it. The maximum response acceleration product was first determined in used as parameter for evaluating damage. Furthermore, drop test carried out to verify theoretical showed good consistency. Based on correct...

A full-scale experimental program was used in this study to investigate the structural behavior of novel insulated concrete sandwich wall panels (SWPs) reinforced with grid-type glass-fiber-reinforced polymer (GFRP) shear connectors. Two kinds of insulation-expanded polystyrene (EPS) and extruded polystyrene (XPS) with 100 mm thickness were incased between the two concrete wythes to meet the in...

Plastic pollution of the natural environment is ubiquitous, and around 40% all plastic waste produced globally used in single-use products only 9% recycled. From this waste, expandable polystyrene pose a major problem because its great volume low density. To abord issue, authors proposed circular economy model for EPS post-consumer 2019 through case study with help one local manufacturer. Altho...
