Shell forms for egg-shaped concrete sludge digesters: A comparative study on structural efficiency

A. Zingoni

Abstract

The structural feasibility of a variety of non-conventional sludge digesters, in the form of thin shells of revolution constructed in concrete, has formed the subject of investigation of a recent programme of research at the University of Cape Town. Such forms are usually known in the literature as

Key Words
