Feasibility of Using Sewage Sludge as Construction Materials
The purpose of this research is to efficiently treat sewage sludge discharged from sewage treatment plants and to evaluate the feasibility of construction materials made from a large quantity of sewage sludge. For this purpose, result of using sewage sludge in Water absorption, Linear firing shrinkage, Weight loss on ignition, Compressive strength and Bulk density of brick was investigated. Then physical properties (density, porosity, and absorption capacity) and especially the mechanical properties (compressive strength, flexural strength, and elastic modulus) of concretes containing sewage sludge were investigated. Results of the research indicated that the sludge proportion is a key factor in determining the brick and concrete quality. Then chemical and physical properties of dray sludge from drying sludge bed of SHAHRAK e GHODS wastewater treatment was investigated the result show that we can save 2000 tons of soil in Tehran with using sewage sludge as constructions material.
