  • Method for making a plastic aggregate
    Patent number: 6030572
    Abstract: A method for producing a plastic aggregate for use in concrete compositions includes exposing high density plastics to ultraviolet irradiation in the presence of a strong alkali. The plastic may be recycled plastic which has been washed and cut into strips. Plastic aggregates according to the invention have an increased affinity for common concrete binders such as portland cement. A cement composition made with such plastic aggregates may include up to 60% by volume of plastic aggregate. The plastic aggregates are well adapted for use in concrete compositions used to make pre-cast concrete components.
