The polystyrene aggregate concrete was produced by partially replacing coarse aggregate in the reference (normal weight) concrete mixtures with equal volume of the chemically coated crushed polystyrene granules.
Polystyrene-bead concrete properties and mix design
1982年8月1日 · Polystyrene-bead concrete is used to form the cores of concrete sandwich beams and slabs in current research in the University of Durham. The paper describes the properties of the material and suggests a method of mix design.
Effect of Expanded Polystyrene Beads on Mechanical, Thermal, …
2024年4月25日 · The optimal mixture for expanded polystyrene (EPS) beads-based lightweight concrete, i.e., EPLC (0.5,2.5,3), (0.5,3,4), (0.5,3.5,3), was determined by considering lower density, even beads distribution, and adhering to minimum ACI …
Review of concrete with expanded polystyrene (EPS): …
2022年9月15日 · The mix design had a water-to-cement ratio (w/c) of 0.38–0.43 and a superplasticizer content of 2.5 kg/m 3. The authors varied EPS content from 0%, 25%, 50%, 75%–100% of natural aggregate by volume and resulted in the densities ranging from 980 kg/m 3 to 2025 kg/m 3 without any segregation of fresh mixtures.

2020年9月29日 · Precast concrete sandwich systems containing expanded polystyrene (EPS) is gradually replacing the conventional blockwork systems due to its lightweight, enhanced insulation properties and...
Abstract: We developed a new structural light weight concrete by completely replacing coarse aggregate in concrete by expanded polystyrene (EPS) beads. Expanded polystyrene (EPS) is a lightweight material that has been used in engineering applications since at least the 1950s.
Polystyrene-bead concrete properties and mix design
Polystyrene aggregate concrete is one of many lightweight and low strength materials. This project reports the results of an experimental investigation into the properties of hardened concrete bricks …
(PDF) Mixing Procedure and Strength Prediction in EPS Concrete
In this research, 8 concrete mix designs with density about 700 kg/m 3 were made. The results of this research show that using silica fume and air entraining agent can decrease segregation of EPS grains and improve bonding between EPS and cement paste, so the concrete mixture will have more homogeneity.
Expanded polystyrene waste replaces coarse aggregate to produce light weight non-structural concrete with unit weight varying from 950 to 2000 kg/m3. Metakaolin is a valuable supplemen-tary cementitious material for concrete and cement applications. Usually 8–20% (by weight) of Ordinary Portland Cement is replaced by Metakaolin.
Design and production of sustainable lightweight concrete …
2021年11月26日 · Precast concrete sandwich systems containing expanded polystyrene (EPS) is gradually replacing the conventional blockwork systems due to its lightweight, enhanced insulation properties and rapid installation. Research has shown that the system’s technical properties are highly dependent on the mix design and the production and installation methods.
