Process for accelerating cure and enhancing ultimate strength of prefabricated masonry structures

摘要

A process for accelerating the cure and enhancing the ultimate strength of prefabricated masonry structures prepared using latex modified portland cement mortar comprising (1) utilizing a portland cement mortar containing modifying amounts of a vinylidene chloride polymer latex and (2) substantially uniformly heating the non-cured prefabricated masonry structure to temperatures of from about 110 DEG to about 210 DEG F under less than about 80 percent relative humidity for a period of at least about 4 hours.
