Abstract

This paper focuses on experimental studies to assess the effect of mechanical and chemical stabilisation on compressed earth blocks strength and durability. The relevance to the performance of compressed and stabilised blocks by moderate portions (less than 10%) of stabilisers such as cement and/or lime, cement and resin has been examined. The experiment consists of testing the stabilised and compressed earth blocks in order to appreciate the compressive strength, the impact of compactive effort, water absorption and finally the resistance against the surface erosion. Additionally, treated walls were exposed to climatic conditions in the aim to relate their durability. The results of the present investigation show that progressive addition of the different stabilisers substantially increases the compressive strength and reduces the water absorption of earth blocks. Furthermore, the improvement of the mechanical and hydrous properties of the compressed earth blocks is stated by rising gradually the moulding pressure. Moreover, under Mediterranean climate exposure, the diagnostic reveals that the walls built with cement or mixed additive are less affected by the damage. In return, the defects including surface roughening, pitting, cracking and erosion concern the un-stabilised or lime stabilised earth block walls.
