Abstract
A concrete composition contain glass, including ordinary recycled glass is provided. The invention also relates to methods of producing the concrete compositions of the invention. A concrete composition containing glass particles, including recycled glass, a substance to mitigate alkali-silica reaction such as E-glass particles, and or pozzolans and/or lithium-containing substances, and cement is provided as well. Compositions containing E-glass (also known as electric glass) and processes for producing E-glass-containing compositions are also provided.
Claims38
A concrete composition comprising E-glass particles, cement, and glass aggregate.
A concrete composition comprising E-glass particles, cement, and reactive aggregate.
A concrete composition comprising E-glass particles as coarse aggregate, fine aggregate, or a combination of coarse and fine aggregate.
A concrete composition comprising glass particles, cement, and aggregate, wherein the size of the glass particles is characterized by a maximum size of from about 30 to about 100 mesh, and from about 40% to about 60% of the glass particles are from about 80 to about 200 mesh, and from about 10% to about 30% of said glass particles are less than 325 mesh.
A concrete composition comprising glass particles, cement, and aggregate, wherein about 0% to about 30% of the glass particles is about 100 mesh, about 50% to about 80% of the glass particles is about 200 mesh, about 10% to about 20% of the glass particles is about 325 mesh, and about 0% to about 20% of the glass particles is below about 325 mesh.
A process for preparing a cementitious component for use in concrete compositions comprising E-glass particles, cement, and aggregate selected from the group consisting of glass aggregate and highly reactive non-glass aggregate, wherein an E-glass component is added during a general processing operation in an unprocessed form along with at least one additional unprocessed cementitious components.
