Abstract
This paper presents the findings from laboratory strength and durability tests on stabilised soil blocks (SSBs). SSBs are masonry units formed by compressing a mixture of soil and a stabiliser such as cement and water in a mould. The strength, density and stiffness of SSBs with 5%, 7,5%, 10% and 20% cement by mass were determined at 7, 14 and 28 days . The SSBs were subjected to different curing regimes to determine the best curing method. The ability of the masonry units to resist prevailing rain, wetting and drying cycles, freezing and thawing cycles, and chemical attack are critical if they are to be used in a European climate. The durability of these blocks was evaluated by cyclic freezing/thawing and wetting /drying tests, as well as by determining the shrinkage, sorptivity and absorption characteristics of the blocks. Through this extensive testing program, it was found that SSBs are a suitable and viable technology for use in a European climate.
