The durability of compressed earth-based masonry blocks

This chapter focuses on the durability of compressed earth masonry - bricks and blocks. It aims to provide a detailed analysis of the factors at play in the determination of durability. Because the durability aspects of compressed earth masonry and those of concrete are broadly common, and because there is by far a larger body of research work in concrete, the chapter borrows heavily, but carefully, from the factors relevant to the durability of concrete. The durability of a brick or brick system depends on a wide range of factors, including the brick materials used, the adopted brick technology, the prevailing environment, appropriateness of use, and care during service, among other possible factors. The detailed analysis of these factors, together with a view of future trends and developments, is the aim of this chapter. The chapter is aimed to capture interest with researchers, trainers, building and construction materials manufacturers and government and local authority policy makers, all who have interests in sustainable development, low-cost housing, appropriate technology, and care for environment and soil-based technology for community infrastructure.
