APPLICATION OF PET BOTTLES FOR CONCRETE MASONRY BLOCKS

Sal, J.; Novakova, P.
Abstract:
The production of cavity blocks, also referred to as concrete masonry blocks (CMU) or concrete lost formwork, takes place in a mobile or stationary press by extruding a special matrix through solid fresh concrete. This production is relatively cheap, simple and fast, provided we have the appropriate press. This article examines whether such concrete blocks can be manufactured without specialized equipment. This can be beneficial, for example, in slums or areas dependent on humanitarian aid, where there is not enough dwelling. On the contrary, in these areas there is a large amount of plastic waste, washed up from the oceans and landfilled in illegal dumps. Several methods of using PET bottles for forming cavities in concrete blocks are proposed in this article. PET bottles can save some of the concrete and create a closed air cavity that improves the thermal properties of the block. Moreover, it is a way to use plastic waste that needs to be recycled and which is a huge problem of the present.
