Patent number: 8172938Abstract: A silica cement blend having an insulating, fire retarding and high temperature characteristic capable of withstanding temperatures ranging from ambient to greater than 40000 F without degradation of the concrete structure. In addition to its high temperature capabilities the blend can be produced as ultra light weight to heavy weight concrete. The silica based mixture when added to cementitious materials such as Portland cement, Class C Fly Ash, silica fume and other cementitious materials. Presented also are methods for reducing fire damage by coating interior/exterior walls, ceiling, and roofs of a building with a water based latex coating containing a fire retardant material and low heat conductivity silicas. Methods for painting internal/external walls, ceilings, and roof are also presented.Type: GrantFiled: June 30, 2009Date of Patent: May 8, 2012Assignee: Specialty Concrete Design, Inc.Inventors: John Alright, David Wayne Taylor
