Foam concrete is a type of lightweight concrete which is lighter than
conventional concrete. It is non-load bearing structural element which has lower
strength than conventional concrete. Foam concrete is widely used in construction
field and quite popular for some application because of its light weight such as
reduction of dead load, non-structural partitions and thermal insulating materials.
Because of its low strength, some material is used in order to increase the foam
concrete strength. A study on the effect of quarry dust as sand replacement
material on compressive and flexural strength of foam concrete was conducted.
This study was conducted to determine the compressive strength and flexural
strength of foam concrete by using quarry as partial sand replacement material.
This report presents the feasibility of the usage of quarry dust as 10 %, 20 % and
30 % substitutes for sand in foam concrete. Mix design was developed for four
different proportion of quarry dust in foam concrete. Tests were conducted on
cubes and beams to study the strength of concrete made of quarry dust and results
were compared with the control foam concrete. It is found that the compressive
and flexural strength of foam concrete made of quarry dust are nearly 40 % more
than the control foam concrete.A
