Behaviour of AR glass fibre for building structural applications

open access: yesMateriales de Construccion, 2005
The AR glass reinforcement fibres were designed to resist the alkalis from the concrete. This is the main reason for its utilisation as a short-fibre-reinforcement of mortar and concrete for the last decades. Originally, the AR glass fibre sizing was not
