Abstract: Historically, concrete and mortar have been used as a flooring and wearing surface because of their availability, durability, and relatively low cost. Under extreme exposure conditions, however, conventional Portland cement mortar and concrete are not sufficient. For example, chemicals, abrasion, and freeze-thaw cycling require that some method of protection be given to the concrete or that another material be used. The most versatile and economical method of protection is a topping of Portland cement mortar modified with saran polymer. The unique chemistry of the saran polymer is such that the mortar bonds tenaciously to the concrete substrate, while maintaining superior chemical and abrasion resistance to most environments encountered in chemical and processing plants. Chemical exposure tests, as well as 10 yr of history, have demonstrated the performance of this modified mortar.
