Steel Reinforced Grout (SRG) systems, made of high strength steel textiles externally bonded with inorganic matrices, have been recently introduced in the market and installed in the field, as a promising retrofitting solution for both masonry and concrete structures. Despite their well-known advantages, such as their high strength-to-weight ratio, their ease of application on irregular and even wet surfaces, their high vapour permeability and their resistance to high temperature, few information on the durability of these systems is available in the literature. In this paper, the influence of freezing-and-thawing conditioning process on the SRG-to-substrate bond behaviour is experimentally investigated, by performing single-lap shear bond tests on steel fabric strips applied on concrete blocks by means of geopolymer-based mortar.

Abstract
Steel Reinforced Grout (SRG) systems, made of high strength steel textiles externally bonded with inorganic matrices, have been recently introduced in the market and installed in the field, as a promising retrofitting solution for both masonry and concrete structures. Despite their well-known advantages, such as their high strength-to-weight ratio, their ease of application on irregular and even wet surfaces, their high vapour permeability and their resistance to high temperature, few information on the durability of these systems is available in the literature. In this paper, the influence of freezing-and-thawing conditioning process on the SRG-to-substrate bond behaviour is experimentally investigated, by performing single-lap shear bond tests on steel fabric strips applied on concrete blocks by means of geopolymer-based mortar.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
