Concrete's drawback is its low tensile strength and heavy weight, which may exceed 2400 kg/m3. The significance of self-weight in building construction essential, particularly when dealing with seismic loads. larger the inertial force from weight structure itself, greater therefore lightweight concrete can provide an opportunity to lower own a smaller unit 1850 Fly ash was employed as substitute for cement this investigation, while pumice used coarse aggregate. goal research establish compressive strength, workability/slump value concrete. In 30% fly utilised. Pumice determined at 0%, 5%, 10%, 15% SN sample has highest slump 8.8. However, continued fall addition pumice. use stone results reduction volume up 1845 kg/m3, permitting it be classified been demonstrated diminish by 11% on average every 5% replacement.
