Abstract
A premixed ultra-light sandless mortar for use with clay and concrete tiles. The mortar uses ASTM standard C-332 aggregate, vermiculite or perlite aggregate in place of heavy aggregates such as sand. The mortar cement is made from portland cement, lime, air entraining agents, and water repelling agents. The resulting compound retains large amounts of moisture which increases hydration time resulting in improved bonding strength, and increased tile uplift strength. The light weight of the mortar also allows a full bed of mortar to be laid on the roof with the resulting benefit of an addition insulating layer for the building. The mortar is suitable for roofing or floor tile applications.
