Abstract

Post-installed anchorages are used extensively in civil and structural engineering worldwide in both structural and nonstructural concrete constructions. The most used anchoring material is the polymer-based chemical resin which have some undisputed advantages, but the long-term performance over the expected service life is under concern.The paper presents a mix design approach of an alternative anchoring material which consist in well suited mortars with advanced characteristics in the fresh and hardened state. The anchoring material is a supplementary cementitious material Portland cement-based mortar used as structural bonding material for fixing reinforcing steel bars in hardened concrete.A series of standardized tests were performed within the experimental setup with the objective of assessing the performance of the mortars in terms of consistence, cohesiveness, strength and adherence.
