Repair Mortar for Structural Sustainability
Objectives: Study on the engineering properties of fiber reinforced polymer cement mortar with incremental replacement of cement by silica fume, Granulated Blast Furnace Slag (GGBS) and Metakaoline (MK). Methods/Statistical Analysis: Cement is replaced by the additives as 5, 10 and 15 percent by weight. Polymer content (SBR) was varied as 5, 10, 15 and 20 percent by weight of water to be added. The FRP fiber addition is optimized to one percent by weight of cement in all the specimens. The intention was to study the variation in engineering properties of fiber reinforced polymer with additive replacement of binder with the additives and water with polymer. Findings: It is concluded from the test results that the compressive and flexural strength of modified mortar were improved markedly with increasing polymer binder ratio and also additive replacement of binder weight by silica fume, GGBS and Metakaoline. The results obtained has given much higher values when compared to individual addition of additives or polymer. The consistency in values of both compressive and flexural strength marks the much higher efficiency of the mortar even in lower percentage of addition of additive or polymer when added individually. Supplementary Cementing Materials (SCM) have growing importance in the construction industry, as it upgrades the economic and engineering efficiency of cement compositions. The replacement of water with polymer reduces the water binder ratio, driving to high strength and durable repair mortars. The polyester fibers addition resulted in the improvement of the mechanical properties of the composition. Applications/Improvements: Thus the fiber reinforced mortar combination is a mark in structural sustainability of not only modern but also for structural rehabilitation of historic monuments, where it can replace the ancient lime mortars with high strength and durability hand in hand.
