  • Patent number: 5383967
    Abstract: A concrete composition including a naturally-occurring, mineralogic silica source material as part of the binder. The silica source material may be, for example, feldspars, naturally-occurring zeolites, diatomaceous earths, clinoptilites, mordenites, chabozites, opaline silicas, novaculites, vitreous volcanic rocks (rhyolites, dacites, latites, andesites and their tuffs, and basalts), and high silica rocks (such as quartzite sands, sandstones and many igneous and metamorphic rocks such as. granites and schists), among others, having at least 50% by weight silica. The cementitious binder of the concrete composition may have a silica content of about 20-40% by weight from the mineralogic material. The compositions exhibit improved strength and endurance, including greater density and smoothness which imparts significantly improved surface characteristics to the material.
