Abstract: The effect of polymer addition on the rate and the extent of alkali silica reactions in mortars containing high alkali concentrations has been investigated.
A bicomponent poxy resin was added to the mortars formulation up to a 20 wt%of cement content.
Mortars were subjected to accelerated curing at 80 °C.
Mortars of the same composition,but formulated without reactive aggregates,were also cast and subjected to the same curing procedure.
Their microstructure,mechanical properties,dimensional stability and calcium hydroxide content were thus investigated.
As the polymer content increases,mortar expansion is reduced:hypotheses for this behaviour,based on the microstructural characteristics of the composites,are proposed.
