Use of Water Treatment Plant Sludge (WTPS) as a Cementitious Material in Concrete
Water treatment plants are generating increasing amounts of sludge, which is creating a significant environmental problem globally. Disposing of WTPS is now a significant environmental issue in developing countries like Bangladesh. The major objective of this study was to investigate the characteristics of WTP sludge, such as physical, chemical, and morphological, and evaluate its impact on concrete performance and mechanical properties. The SEM–EDX testing method is used to determine the physical, elemental, and morphological properties of the WTP sludge. The results revealed that the particles of the sludge possessed an irregular shape with a predominantly rough texture on their porous surface. The results of the EDX experiment indicated the presence of seven distinct elements within the WTP sludge. These elements were found to be present in the following descending order of percentage mass: Oxygen (41.95%) > carbon (40.05%) > silicon (7.80%) > luminium (5.80%) > iron (2.89%) > potassium (1.08%) > magnesium (0.43%). The ACI 211.1 code was used in this study for the design of a concrete mix with strength of 3000 psi after 28 days. During the experiment, cement was replaced with WTP sludge (WTPS) at varying percentages ranging from 5 to 40%. The results indicated that as theamount of WTPS replacement increased, the compressive strength of the concrete gradually decreased. However, the maximum workability was achieved at a 15% replacement rate.
