Resumo: Abstract This research aims to study the effect of supplementary cementitious materials (SCMs) such as quarry dust limestone (QDL) and natural pozzolana (NP) on the performance of fiber reinforced self-consolidating repair mortars (FR-SCRMs). Based on previous optimization of QDL and NP replacement ratios, two mortar mixtures incorporating 10% QDL and 20% NP as cement replacements were prepared. The evaluation was based on both fresh (slump flow, flow time) and hardened (compressive and flexural strengths and adherence to old concrete) tests. In addition, the influence of three curing conditions, similar from those normally encountered in the field was evaluated on the compatibility between repair materials and substrate, under flexural strength test by using third-point’s loading beam test method. It is demonstrated that the FR-SCRMs is promising to be used in repair concrete structures class R4 (EN 1504-3) without reducing the adhesive strength.
