Physical properties of oil-rich sludge-clay mixed bricks

Oil-rich sludge (ORS) is a by-product of oleochemical industry. The present study was aimed to investigate the influence of sludge on the mechanical and durability properties of clay brick. Eight partial replacements of 5 %, 10 %, 15 %, 20 %, 25 %, 30 %, 35 % and 40 % of sludge types in clay formula...
