ABSTRACT:
This invention pertains to a process of making ASTM quality masonry cement, mortar cement, and stucco cement (also called plastic cement) and to the products themselves which are useful in making ASTM quality mortar for masonry construction or ASTM quality stucco for plastering construction. These cements are classified as hydraulic cements and are made using selected pozzolan(s), such as natural pozzolan and fly ashes, Portland Cement, hydrated lime, and an air-entraining agent. Other additives, such as fibers, may be added to further modify its properties. The pozzolans act as functional ingredients in the mix rather than as a filler. As a result, concentrations of greater than 25 wt. % and more pozzolan can be produced.
