Szukana fraza: [Abstract = "We carried out tests on mortar in the fresh state \(consistency, density and occluded air\)\; evaluated its performance in the hardened state \(compressive and flexural tensile strength\), dimensional stability and its durability \(water absorption by immersion and by capillarity as well as resistance to chlorides and acidic environments followed by XRD\). Results obtained will be compared with the results of control samples with 0% substitution rate. The results of this valorisation show that the incorporation of 5% of ash fillers in the cement improves mechanical resistance as well as certain durability parameters."]
