A NEW METHOD FOR QUICK DETECTION OF REACTIVE AGGREGATE IN MORTAR AND CONCRETE

This study suggests a new way for quick detection of reactive siliceous and silicated aggregates. The principle of the method consists of hydrolysing an ester in the interstitial liquid of the concrete so as to release the corresponding acid. The acid causes the gelling of the colloidal solution and serves to reveal the reactive aggregates. Different techniques can be used to evaluate the quantity of gel (permeability measurements, compressive strength, volume variations, etc). (A) For the covering abstract see IRRD 871351.
