Where concrete structures have deteriorated due to corrosion and where changes in use and/or design code do not need an increase in loading capacity, POLYMER MODIFIED MORTARS can be used to repair concrete structures efficiently. Polymer modified mortar can be used in structural repairs. Because the structures were initially built using a concrete mix (1 cement: 1.5 sand: 3 coarse aggregates) with a minimum strength requirement of 20 N/mm2 min., it was concluded that the polymer modified repair mortar would have to have a compressive strength of 25 N/mm2. According to the polymer test reports, the concrete mix used in the construction of these buildings, and the level of damage. Contractor for Polymer Modified Mortar
