Alkali-activated concrete (AAC) is mounting as a
feasible alternative to OPC assimilated to reduce greenhouse gas
emanated during the production of OPC. Use of pozzolana results
in gel over-strengthening and fabricate less quantity of Ca(OH)2
which provide confrontation to concrete against hostile
environment. (AAC) is potential due to inheriting the property of
disbursing CO2
instantly from the composition. Contrastingly an
option to ordinary Portland cement (OPC), keeping this fact in
mind the goal to evacuate CO2 emits and beneficiate industrial
by-products into building material have been taken into
consideration. Production of alkali-activated cement emanates
CO2 nearly 50-80% less than OPC. This paper is the general
assessment of current report on the fresh and hardened properties
of alkali-activated fly ash (AAF), alkali-activated slag (AAS), and
alkali activated slag and fly ash (AASF) concrete. In the recent
epoch, there has been a progression to blend slag with fly ash to
fabricate ambient cured alkali-activated concrete. Along with that
the factors like environmental friendliness, advanced studies and
investigation are also mandatorily required on the alkali activated
slag and fly ash concrete. In this way, the slag to fly ash
proportion impacts the essential properties and practical design of
AAC. This discusses and reports the issue in an intensive manner
in the following sections. This will entail providing a good
considerate of the following virtues like workability, compressive
strength, tensile strength, durability issues, ambient and
elevated-temperature curing of AAC which will improve further
investigation to elaborate the correct test methods and to
commercialize it.
