INTRODUCTION:
Safeguarding that every nation's citizen lives in a sustainable and clean environment is one of the most critical challenges facing governments today. The remarkable growth in construction activity has greatly increased the demand for river sand, diminishing and utilizing natural sand resources and having negative environmental backlashes like falling water table and slipping of river edges. So, it is essential to find an alternative material that can be used in place of river sand and crushed sand while making concrete.
Bakelite was invented by Leo Baekeland in 1907 and patented in 1909. It was the first synthetic plastic and marked the beginning of the Polymer Age. Bakelite is formed through condensation reaction of phenol and formaldehyde. In this reaction, phenol and formaldehyde react to produce o-hydroxymethyl phenol, which then reacts with phenol to form Bakelite. It is a thermosetting phenol-formaldehyde resin. Earlier it was used in jewelry (vintage jewelry) and due to its resistance towards heat it is used in kitchen utensils over their handles. Also it is used in electrical appliances such as telephones, adaptors, switches, plugs, insulators and more. Because of its huge demand it leads to the extreme generation of waste, around 80,000 tons of Bakelite waste was generated in India in year 2020. It is a thermosetting plastic that hardens permanently when exposed to heat and pressure. However there are some ways to recycle or reuse Bakelite and our topic is one of them i.e. Bakelite Waste In Concrete. The chemical formula for Bakelite is (C6H6O-CH2OH)n. It has more than 50% carbon present in it so we can’t use it for structures near water bodies, as it will result in water pollution. We can use it in blocks, light structure and also in roads. It can also be used in WBM road.
