In this paper, the use of waste plastic as modifier for aggregates (plastic coating aggregate) was investigated and the test results had demonstrated that there was an improvement in the properties of plastic coated aggregates.Abstract:
Rapid growth of plastics industries in Asia's emerging markets particularly in Malaysia, in one way, it raised expectations for everyday comforts, in the other way it also causes environmental issues. Plastic bottle for recycling can be found from the household waste stream, and most of them are made from Polyethylene Terephthalate (PET). Recycling this plastic into another form might be one of the cheapest and rapid solutions. However, turning this plastic into some other usable form uses energy and this may not become a green waste management solution. In this research, PET is utilized to explore its potential prospects to upgrade asphalt mixture properties. This study investigates the use of waste plastic as modifier for aggregates (plastic coating aggregate). The type of plastic used in this study was waste PET plastic bottle. The shredded waste PET plastic (size 0.075mm to 1.18mm) was mixed with hot aggregate to form a thin layer on the surface of the aggregates. The properties of modified aggregate and unmodified aggregate was tested and compared. 1% and 2% of plastic by weight of aggregate were used to coat the aggregate. The plastic-coated aggregates are tested for impact value and crushing value. The test results had demonstrated that there was an improvement in the properties of plastic coated aggregates.read more

Energy performance of building envelopes integrated with phase change materials for cooling load reduction in tropical Singapore
TL;DR: In this paper, the energy performance of building envelopes integrated with phase change materials (PCMs) for cooling load reduction in tropical climate through numerical simulations was investigated and the results showed that PCM can effectively reduce heat gains through building envelope throughout the whole year, indicating the significant advantage of the use of PCMs in tropics over other regions where PCMs are only effective in certain seasons.
