Manufacturing Light Concrete with PET Aggregate

Abstract. The manufacture of concrete using a polymer instead of a stony coarse aggregate known as gravel is presented. Polyethylene terephthalate (PET) is the polymer used, recycling soft drink containers with sufficient tenacity.PET is a material commonly used by engineers as a structural element, not as an aggregate.
