However, compressive strength at 05% recycled aggregate and 05% stone dust is marginally than that of conventional concrete. The compressive strength of 05% stone dust and ceramic waste sample is in close proximity of the referral concrete. Thus, it can be concluded that stone dust up to 05% with 05% ceramic waste aggregate is satisfactory …
