Results: The experiment results indicate that the type of recycled aggregate and its replacement ratio have significant effects on the freezethaw performance. The cubic compressive strength of recycled aggregate concrete is overall slightly lower than that of normal concrete. After 100 freeze-thaw cycles, the compressive strength decreases and the reduction extent increases with increasing repl...

The main aim of this research is to study the possible use of recycled fine aggregate made from waste rubble wall to substitute partially for the natural sand used in the production of cement and sand bricks. The bricks specimens were prepared by using 100% natural sand; they were then replaced by recycled fine aggregate at 25, 50, 75, and 100% by weight of natural sand. A series of tests was c...

Abstract The use of recycled plastic in asphalt pavements represents a sustainable and economic choice which, if correctly designed, could significantly improve the resistance against typical distresses flexible pavements. For this reason, paper aims at evaluating mechanical properties two mixtures modified with plastomeric compounds through dry method, by comparing their results those obtained...

Abstract Autonomous polymers that report damage prior to loss of function and simultaneously self-heal are highly relevant for preventing catastrophic failures extending the lifetimes materials. Here, we demonstrate mechanochromic thermally reprocessable thermosets can be used autonomic reporting self-healing coatings. A molecule, spiropyran (SP), is covalently incorporated into thermoreversibl...

In this paper, we study how voluntary recycled content claims made by a manufacturer are impacted by recyclate supply uncertainty and demand benefit for recycled products from environmentally conscious businesses and governments. We identify two types of recycled content claims product specific claims for which manufacturer makes the recycled content commitment for each product (e.g., paper nap...

The aim of this work is to investigate the performance variability post-industrial (PIR) and post-consumer recycled (PCR) polycarbonate acrylonitrile-butadiene-styrene (PC-ABS). In addition, necessary testing methodology for understanding polymer variation in polymers are established. thermal expansion behaviour all tested material were found be similar FT-IR revealed no conclusive evidence oxi...

The recycling process is the best way to manage waste polymers. From an economic standpoint, more investigation needed of whole enhance competitiveness in these systems. A first step improved interaction and interfacial adhesion blends. Polyethylene (PE) polyethylene terephthalate (PET) are incompatible polymers, so their blends general have poor properties. Compatibilization thus a necessary o...

With a constantly growing population, water scarcity becomes the limiting factor for further social and economic growth. To achieve a partial reduction in current freshwater demands and lessen the environmental loadings, an increasing trend in the water market tends to adopt recycled water for household laundries as a new recycled water application. The installation of a small pre-treatment uni...

One of the major challenges of our present society is the protection of environment; with respect to this some of the important elements are reduction of natural raw materials and consumption of waste materials. The recycled aggregate sample of size 20mm which is the maximum size of aggregate in reinforced cement concrete is collected from demolished structures in our surrounding areas and the ...

In this study we evaluated the tribological performance of polypropylene composites with wood-flour fillers obtained as a by-product from wood-processing industry, which were based on unrecycled and recycled polymer matrices. The mechanical properties polypropylene-wood wood-filler loadings 0–40 wt % determined tensile tests their friction wear behaviours studied dry reciprocating ball-on-disc ...
