Abstract
A silica cement blend is provided having insulating, fire retarding and high temperature characteristics that is capable of withstanding temperatures greater than 4000° 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. Also provided 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.
