摘要

富油污泥是石油化工生产的副产物。本研究旨在探讨污泥对粘土砖力学性能和耐久性的影响。对粘土配方中5%、10%、15%、20%、25%、30%、35%和40%污泥类型的8种部分替代进行了评价。采用50mm × 50mm × 50mm均匀尺寸的800块砖,手工成型,900℃炉烧,进行吸水试验和压缩试验。结果表明,污泥混合砖的吸水率随污泥用量的增加而增加。吸水率在29% ~ 69%之间。砖的抗压强度范围在0.85 N/mm2和13.26 N/mm2之间,其中湿污泥和干污泥显示出更高的抗压强度,超过5 N/mm2,部分替换高达20%。ORS掺量在20%及以下的粘土砖质量较好。用ORS配制的砖对建筑经济和环境都有好处。

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 formulation were evaluated. Eight hundred bricks with uniform size of 50 mm × 50 mm × 50 mm were hand-molded, burnt in a furnace at 900 oC, and were subjected to water absorption test and compressive test. The result shows that the water absorption of sludge blended bricks increased with increasing amount of sludge. The water absorption percentage is between 29 % and 69 %. The compressive strength of bricks is ranging between 0.85 N/mm2 and 13.26 N/mm2, whereby wet and dry sludge revealed a greater compressive strength of more than 5 N/mm2 for partial replacements up to 20 %. Clay with 20 % and less blend of ORS shows good quality of brick. Brick formulated with ORS could be beneficial for the construction economy and environment.
