Workability and strength characteristics of alkali activated mortar with various binder systems

Abstract

Determining the workability and mechanical behaviour of alkali-activated mortar (AAM) cured under atmospheric air conditions with diverse industrial waste materials as binder precursors are the prime goals of the current research. The different combinations of slag and fly ash with class C and class F grades were utilized for preparing the AAM and flow table test, compressive strength test and flexural strength test were done in the laboratory to assess the performance of mortar. The results showed that the increase in slag content improves the mechanical behaviour while adversely affecting workability. This study suggests that alkali-activated systems could replace conventional cement concrete in construction projects if properly designed with.
