Patent number: 10358387Abstract: A refractory composition is formed by preparing a set retarded fresh cementitious composition formed from a class C fly ash, a set retardant such as boric acid, and an alkali activator such as an alkali metal citrate salt, and contacting the set-retarded fresh cementitious composition with a pH regulator, such as an alkali metal hydroxide or alkali metal carbonate. The set retarded mixture provides workability and avoids equipment fouling caused by premature setting, while the alkali activator provides rapid setting when desired. The cementitious composition is shaped into a brick, panel, slab, concrete fire log, or the like and allowed to harden. The hardened cementitious composition can be heated to form a dried cementitious composition, and further heated to produce a high strength refractory composition. Fibers and/or aggregates may be included.Type: GrantFiled: October 4, 2016Date of Patent: July 23, 2019Assignee: EVERBURN MANUFACTURING, INC.Inventor: Raymond C. Turpin, Jr.

Patent number: 10233119Abstract: Cementitious compositions and methods for preparing and using the cementitious compositions to yield hardened concrete. The cementitious compositions yield hardened concrete having reduced or attenuated water vapor emission and lower internal relative humidity (IRH). Cementitious compositions are characterized by the property of rapid surface drying while maintaining good workability, particularly when using porous lightweight aggregates that absorb substantial amounts of water. Methods of decreasing water availability and increasing surface drying of concrete, including lightweight concrete, are provided. A water soluble ionic salt may be used to sequester water within the pores and capillaries of the cement paste and/or porous lightweight aggreate by modifying the colligative propertie of pore water.Type: GrantFiled: July 1, 2016Date of Patent: March 19, 2019Assignee: US Concrete, Inc.Inventors: Alana Grace Guzzetta, Ryan Allen Henkensiefken, Raymond C. Turpin, Jr.

Patent number: 10077210Abstract: A lightweight aggregate for use in forming lightweight cementitious mixes and/or concrete is formed by encapsulating a plurality of hydrophobic polymer particles (e.g., expanded polystyrene particles) in an encasement having a first layer of a cementitious material and a second layer of a pozzolan or mineral. The lightweight aggregate can be included as at least part of the aggregate component of a cementitious mix to form a lightweight cementitious mix. The lightweight aggregate and/or lightweight cementitious mix can be used to form lightweight concrete. The encasement of the lightweight aggregate allows the cement of the cementitious mix or concrete composition to bond to the lightweight aggregate, thereby promoting strength and durability of the concrete mixture.Type: GrantFiled: May 12, 2016Date of Patent: September 18, 2018Inventor: Raymond C. Turpin, Jr.

Patent number: 10000414Abstract: Cementitious compositions and processes for preparing and using the cementitious compositions are provided. The cementitious compositions are characterized by the property of a reduced or an attenuated water vapor emission from a cementitious mix and a concrete formed therefrom. Certain cementitious compositions are characterized by the property of accelerated drying while still maintaining good workability. Methods of improving water retention and surface drying of concrete, including lightweight concrete are provided. A water soluble ionic salt may be used to sequester water within the pores and capillaries of the cement paste and/or porous lightweight aggregate. In some examples, the salt may be added directly to concrete or aggregates may be infused with a water-salt solution to provide treated porous aggregates having improved water saturation and water retention.Type: GrantFiled: September 28, 2015Date of Patent: June 19, 2018Assignee: U.S. CONCRETE, INC.Inventors: Alana Guzzetta, Ryan Allen Henkensiefken, Raymond C.

Patent number: 6451105Abstract: A cementitious composition comprising Portland cement and a finely divided limestone accelerator. The Portland cement has a fineness of at least about 3,200 Blaine. The composition may contain one or more blast furnace slags or pozzolans, such as fly ash or silica fume.
