The utilization of the sewage sludge is restricted and, in several cities, it is simply incorporated into the soil as sanitary embankment or as organic fertilizer for agriculture. On the other hand, due to its chemical composition, it is advisable to study the possibility of being used in the production of pozzolanic material through calcinations. The pozzolanic reactivity is determined by the lime consumption measured in mg by gram of pozzolanic material. The performance of the material confirmed its excellency.
