This research investigated the performance of lime-BHA (black rice husk ash) solidified plating sludge with 2 wt% NaO from Na(2)SiO(3) and Na(2)CO(3) at the level of 0, 30 and 50 wt%. The sludge was evaluated for strength development, leachability, solution chemistry and microstructure. The lime-BHA solidified plating sludge with Na(2)SiO(3) and Na(2)CO(3)(More)
This research investigated the possibility of deteriorated working mold (DWM) as a coarse aggregate for lightweight aggregate concrete (LWAC), which divided to two parts; Effect of coarse aggregate (CA) replacement with DWM and the ratio between coarse aggregate and cement (A/C) on properties of LWAC. The ratio of ordinary Portland cement (oPC): sand: CA(More)
This research studied the effect of water treatment residue (WTR) and calcium carbide residue (CCR) on properties of compacted clay liner. The mixtures were made from clay with 0, 5, 10 and 15 wt.% of CCR and 0, 50 and 100 wt.% of WTR. The consistency of grained, compressive strength and permeability of liners were investigated. The experimental results(More)
