Experimental correlation between varying processing parameter and compressive strength of polymer-modified cement mortar composites

Experimental correlation between varying processing parameter and compressive strength of polymer-modified Cement Mortar Composites was investigated. Polymer-modified Raffia fiber (RPF) cement mortar was developed by varying the RPF from 0 to 25%. Polyester and polyvinyl alcohol (PVA) were used in the production of the cement mortar. The curing time of 28 days were used. Compressive strength of the developed composite was examined. Factorial design of the experiment can be successfully employed to describe compressive strength of the cement mortar. The results show that increasing the volume percent of RPF from 0 to 25 vol% decreased the compressive strength compressive strength by (− 3.55(PVA), − 3.815(polyester)). Polymer-modified cement mortar has a positive effect on the compressive strength by (2.12(PVA), 1.22(polyester)). The curing days appear to be the most important variable with main effect of (5.043(PVA), 7.535(polyester)). The developed linear equation model can be used in predicting the compressive strength of the composites within the selected experimental conditions.
