  • Recycled plastic aggregate for use in concrete
    Patent number: 10294155
    Abstract: The synthetic recycled plastic aggregate for use in concrete is a composite material containing between 30% and 50% by weight shredded recycled plastic, the balance being a filler embedded in a matrix of the recycled plastic. The recycled plastic includes polyethylene terephthalate (PET). The filler can include dune sand, fly ash and quarry fines. The synthetic recycled plastic aggregate is best used to make concrete with a water-to-cement ratio of at least 0.5.
    Type: Grant
    Filed: July 21, 2017
    Date of Patent: May 21, 2019
    Assignee: King Saud University

  • Synthetic aggregate for use in concrete
    Patent number: 8921463
    Abstract: The synthetic aggregate for use in concrete is a composite material of recycled plastic having a filler encapsulated in the plastic. The synthetic aggregate includes between 30% and 50% recycled shredded plastic, the balance being filler. The plastic may be linear low-density polyethylene (LLDPE). The filler can include red sand, fly ash and quarry fines. The synthetic aggregate is best used to make concrete with a water-to-cement ratio of at least 0.5. A method of making the synthetic aggregate includes the steps of mixing plastic with filler to form a homogenized mixture, compressing the homogenized mixture in a mold, melting the plastic in the homogenized mixture to form a composite sheet or slab, and shredding the composite sheet or slab to form either coarse or fine aggregates for use in making concrete.
