Abstract
According to the U.S. Stabilisation is the best-proven technology now in use, according to the Environmental Protection Agency’s definition in Title 40, Part 268 of the Code of Federal Regulations (40 CFR 268).This method prevents harmful contaminants from leaking into the environment by physically and chemically trapping them all in a matrix. The investigations used 15 different water-mixed combinations of cement, fly ash, sinter, and lime. The study also examined the best solidification/stabilization method for encasing heavy metals, an inorganic hazardous waste, in cement to produce a non-hazardous end product. Compressive strength and metal concentration in the leachate of the stabilized/solidified product were analysed. The solidification procedure can produce sludge with a compressive strength of 68 kg/cm2 when the additives are added and the mixture is cured at 23°C for 28 days. The best mixes (in terms of UCS) contained the highest compressive strengths, which are almost 18 times the minimal criteria value, proving the significant success of using sinter for solidification. The optimum mixtures have a sludge:additive ratio of 60:30 and additives with a cement content of 15%.
