Abstract

Concrete is one of the oldest and most common key materials in the construction and maintenance of wastewater transitional structures, which is considered by the designers and contractors. Corrosive materials in wastewater such as hydrogen sulfide, etc. cause corrosion at the concrete level, which over time leads to reducing their strength and therefore concrete structures mechanism. On the other hand, the increasing advancement of using composites in various industries created the idea of creating a new generation of composite materials known as FGMs for the first time in 1984 in Japan. FGMs are composites, in which the microscopic properties change with the non-uniform, smooth, and steady distribution of its original composition. Therefore, these materials are usually in the category of inhomogeneous materials that are assumed to be isotropic. This paper aims to investigate the application of the structural element of metal -ceramic FGM plates to design the plate elements of the floor, wall, or ceiling in cylindrical and rectangular concrete tanks of wastewater treatment plants sludge storage in order to extend the life of structures against corrosion caused by wastewater instead of concrete tanks. In addition, the previous structural results of the application of metal-ceramic FGM plate s are the consumed elements used in the wall and floor slab on the support or on the substrate is elastic or Pasternak.
