Analysis of the maturation process of geopolymer mortars
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.Peer ReviewedPostprint (published version
