Embodiments of the present invention described herein relate to fiberglass materials, composite glass materials, methods of making fiberglass materials and composite glass materials, and different applications of fiberglass materials and composite glass materials. The fiberglass materials can include a bimodal particle size distribution. The fiberglass materials can include an average aspect ratio of greater than about 2 to 1. Also described herein are composite glass materials including a first glass material and a second material. The second material can include at least one of post-consumer glass waste, fly ash, metakaolin, and slag. Also described herein are methods of making a composite glass material including providing a first glass material to a mixer; providing a second material to the mixer; and co-milling the first glass material and a second material to form a composite glass material.

Fiberglass materials, methods of making, and applications thereof

The present invention provides method of contemporaneously forming a particulate glass batch composition and reducing volatile components in an exhaust stream, comprising the steps of: (a) introducing an exhaust stream comprising one or more volatile components into a mixing chamber; (b) adding a particulate glass batch precursor composition comprising at least one reagent material that is reactive with at least one of the one or more volatile components of the exhaust stream into the mixing chamber; (c) reacting at least a portion of the particulate glass batch precursor composition with at least a portion of the one or more volatile components of the exhaust stream in the mixing chamber to form a particulate glass batch composition and reduce the amount of the one or more volatile components in the exhaust stream; (d) separating the particulate glass batch composition from the exhaust stream; and (e) venting the exhaust stream having a reduced amount of volatile components to the atmosphere. In one particular embodiment of the invention, the at least one reagent material is selected from the group consisting of alkali earth compounds, alkali metal compounds, aluminum compounds, silicon compounds and mixtures thereof, and the reagent material is added in an amount that is at least five times a stoichiometric molar amount necessary to completely react with the at least one of the one or more volatile components in the mixing chamber.
