Effects of various reinforcement on mechanical properties of plastic block: A review

Abstract

Solid waste management is one of the major problems of any developing country due to the rapid growth in urbanization and industrialization. In solid waste one of the main components is plastics. Some of the plastics used in household and industrial applications are polypropylene (PP), polyethylene (PE), polystyrene (PS), polyethylene terephthalate (PET) and this kind of plastics can be recyclable but these plastics are simply dumped in landfills and water bodies and then plays a vital role in the causes for environmental pollution and other threats. Degradation rate of plastics also very slow, hence disposal of these plastic wastes without any cautions are not only affecting our surroundings but also affecting humans and other living beings. In addition to plastic waste another one main element is construction waste. Most of these waste plastics and construction wastes such as ceramic waste, metal scraps and quarry dust can be recycled by proper processes and can be reused. These waste plastics can be used to manufacture plastic blocks that may be used in construction works. This paper mainly focuses on the review of researches done on Improving mechanical properties of paver blocks using various waste materials as reinforcement. These plastic paver blocks with reinforcement can be used in nontraffic roads such as walkways, footpaths, pedestrian plazas, landscapes, monument premises and in waterlog areas due to their low water absorption property.

Upcycling Polystyrene

“…Both natural and crushed fine aggregates are commonly used for mortar production in building sectors as energy conservation methods. In addition to aggregates, blocks based on waste plastics and other materials can also be used in construction as a reinforcing strategy [59]. These reinforced plastic paver blocks' low water absorption properties can then be leveraged for application in the landscaping of footpaths, walkways, plazas, monuments, and waterlogged areas [59].…”
