Use of PET bottles waste to substitute sand in cement based mortar applications


By Abdelshakour Awadelkarim Mohammed, Dr Ahmed Ibrahim Ahmed.


The amounts of PET bottles waste are steadily increasing globally. In Sudan the PET bottles wastes average per year for the years 2003 -2015 amounts to 38336 ton. This work aimed to reuse the PET bottles waste as a partial substitute to sand in mortar compositions in form of blocks, bricks, plaster, binding bricks mortar so as to reduce the amount of waste and save the environment from its hazards. Best conditions for the tested variables with 20% PET amount are: 8% water amount, 1% gum amount and 4,76mm size of the PET material. The resulting products from the PET mortar compositions give comparable performance against both compressive and splitting strength.
