Cellular lightweight concrete is a lightweight
concrete that contains numerous, evenly distributed air
bubbles throughout the concrete mixture. These air
bubbles make the concrete lighter in weight than
traditional concrete. On the other hand, cellular
lightweight concrete provides less, strength compared to
traditional concrete due to the presence of pores. Utmost
control is very much needed during its production and
onsite supervision. There are no such Codal provisions
available for the preparation and testing of the physical
and mechanical properties of foamed concrete. The focus
of the study is to add of foaming agent and fly ash as a
partial replacement of cement to fill the pore spaces to
improve the strength of cellular lightweight concrete. In
this study, different percentage of fly ash has been added
and the result has been discussed.
