Contribution to the requalification of Alkali-Silica reaction damaged concrete: particular respect to the slag effect

MATEC Web of Conferences, 2018
A significant concern when designing durable concretes structures is the risk of alkali silkai reaction (ASR). The cracks formed by ASR increase the permeability of concrete, reduce the strength and lower the economic lifetime of concrete.
