Synthetic aggregate for use in concrete

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 plastic, the balance being filler. The plastic may be polyethylene terephthalate (PET), low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), or other recyclable plastics. The filler can include red sand, fly ash, silica fume, rice husk ash, and air cooled slag. The synthetic aggregate is best used to make concrete with a water-to-cement ratio of at least 0.5.The synthetic aggregate for use in concrete is a composite material of recycled plastic having a filler encapsulated in the plastic.
