ABSTRACT
Abstract Spray applied polymer-modified cementitious based materials are now frequently used for the repair of deteriorating or damaged concrete structures. This paper addresses the structural effectiveness of such materials when used in large volume patch repairs. It describes the construction of 1:2.5 scale reinforced concrete frame structures, their repair under various load states and their load testing to failure. Comparisons of behaviour are made with theoretical predictions. The research showed that for the spray applied material investigated, the repaired section behaved in a similar way structurally as if unrepaired, thus giving some confidence in the use of such materials in structural situations. Keywords: Cementitious materials, patch repairs, reinforced concrete, spray applied repairs, structural behaviour.
