Mechanical and maturation of geopolymers mortars based on fly ash –FA¿ (FAM), properties are studied. The values of FAM in compressive strength were lower than conventional Portland cement mortars (PCM). For geopolymers were achieved in some cases compressive strengths up to 24.42 MPa, but in another study variables an abnormal behaviour was identified with loss of compressive strengths and elastic modulus (reaching only 14.51 MPa and 1.24 GPa). This behaviour can be attributed to a possible reaction between the aggregate and the alkaline medium, which appears to increase with +age of curing. Involvement implies that the reaction impedes or disrupts the geopolymerization process of FA, causing less compressive strength.
