Mortars and cements having improved freeze-thaw properties and method of achieving same

摘要

Inorganic mortars, cements, and concrete are subject to crazing, cracking and spalling when subjected to alternate freezing and thawing. The present invention significantly decreases this affect by providing a network of tiny glass filaments having a hydrophilic surface throughout the mortars and cements. Preferably there should be more than approximately 675 lineal inches of network forming filament per cubic inch of mortar.
