✦ Synopsis

In view of the increasing use of pozzolanic materials in hydraulic binders, there is great interest in designing a rapid and efficient method to evaluate their reactivity. The present paper describes a method for the evaluation of pozzolanic activity based on the measurement of compensated conductivity of a calcium hydroxide saturated solution, to which the material is added, over time which is applicable to natural products. Results can be obtained as from a minimum time of two minutes.
