Abstract

A type of lightweight concrete called cellular lightweight concrete (CLC) has a lower
volume weight than ordinary concrete and is made of cement, sand, water, and a foaming agent.
In this investigation, CLC lightweight concrete was utilized as a lightweight brick. The purpose of
this study was to ascertain how the compressive strength and volume weight of CLC lightweight
bricks would change if stone dust were used in place of fine aggregate. Making lightweight bricks
with stone dust substitutions of 0%, 50%, and 100% of the weight of the fine aggregate was the
experimental process used in this study. The compressive strength and volume weight of the light�weight bricks that had been cured for 3, 7, 14, and 28 days were then measured. Because stone
dust has a good binding capacity, the results showed that using it as a fine aggregate replacement
in a mixture of lightweight bricks increased the compressive strength; the highest compressive
strength value was obtained at a substitution of 100% stone dust at 28 days, which was 24.62
kg/cm2
. The volume weight of a mixture of lightweight bricks increased by 0.66 gr/cm3 when stone
dust was used in place of fine aggregate. In place of 50% stone dust, the volume weight value
increased by 2% to 0.67 gr/cm3
, and by 4% to 0.68 gr/cm3 for 100% stone dust. Due to its volume
weight range of 0.6-1.8 gr/cm3
, this lightweight brick can still be designated as lightweight
concrete
