چکیده
Recycling plastic waste has been one of the most significant challenges in recent decade. The reuse produced cellular plastics (i.e. EPS) within a conventional construction binder can contribute, simultaneously, to elimination and improving energy performances building envelopes. This work investigates recycling expanded polystyrene (EPS) cement-based matrix. aim is develop lightweight, energy-efficient composite for eco-construction. Portland cement was mixed with small amount gypsum (4 wt%) before adding EPS aggregates ranging from 0–0.6 wt%. thermal properties were determined using two different non-destructive methods, transient plane source technique (Hot Disk Method) Flash method. experimental results showed remarkable decrease 54, 12, 36% conductivity, diffusivity, density, respectively. These indicate improvement resistance EPS-cement-gypsum- mixes. In addition, water absorption compressive tests revealed that composites containing beads have improved durability be used structural insulation purposes. Finally, Numerical indicated savings up 18% may achieved by applying waste-based mortar, underscoring promise this product efficiency benefits.

Lightweight Geopolymer Concrete with EPS Beads
Activation of class F fly ash with the 10 M sodium hydroxide and sodium silicate and its geopolymeric products were analysed under quasi-isothermal mode of DSC, FTIR and TG/DTA techniques. Before adding in concrete, expanded polystyrene beads were prewetted with the styrenebutadienestyrene latex aimed at to improve their bonding with geopolymer. Lightweight mortars/concretes were made from geop...
متن کاملProperties of Cement Mortar and Ultra-High Strength Concrete Incorporating Graphene Oxide Nanosheets
In this work, the effect of graphene oxide nanosheet (GONS) additives on the properties of cement mortar and ultra-high strength concrete (UHSC) is reported. The resulting GONS-cement composites were easy to prepare and exhibited excellent mechanical properties. However, their fluidity decreased with increasing GONS content. The UHSC specimens were prepared with various amounts of GONSs (0-0.03...
