Abstract:
These research studies waste management from the plastic eyeglasses industry. Use analysis of material flow chart and selection waste from the study of the flow chart of materials sent to landfills and can also be utilized, such as glass powder sludge (GS), mold factory wastewater treatment sludge (MS), And biological wastewater treatment sludge (BS). Study the chemical composition of sludge, found that the MS contains cerium and all three sludges were found to contain silica and alumina. Therefore studied the method of recovery cerium from MS. And all 3 types of sludge are used as sand substitutes in the production of mortars. Using the ratio of cement to sand equal to 1: 2 and water to cement ratio of 0.55 and 0.50. Study the ratio of replacing waste into the sand at 10, 20, 30, 40 and 50 percent by weight, curing time 7, 14 and 28 days. The Cerium recovery has maximum purity of cerium is 38.28 percent. The type of acid and temperature affects the purity of the cerium. The results of the production of mortar that replaced more sand with BS and MS found that the density and the compressive strength is reduced The water absorption increased The mortar that replaced the sand with the GS When replacing more resulting in density And the compressive strength increased to one point and then lower, water absorption showed no change. When compared with the standard of Portland Cement (TIS. 15-2547), it is found that mortar that replaces sand with BS and MS did not meet all standards of the study. The mortar that replaced the sand with the GS found that all standards were studied. The optimum ratio for replacing GS was 30% by weight and 28 days of curing time. Leach testing of heavy metals from mortars Found that the leaching value of heavy metals does not exceed the standards set.
