Walls of Interlocking Stabilised Soil Blocks (ISSBs) have been considered in low-cost houses around the world especially in developing countries. These were reported to be very weak in resisting the lateral load (e.g. wind or earthquake) without special considerations. In this paper, mechanical properties (compressive strength, elastic modulus, pre/post crack energy absorbed and toughness index) of ISSBs with three configurations and seven combinations of plain and fibrous mortar cubes are experimentally evaluated. Sisal fibre and rice straw (2% and 5%, by cement mass) were considered for fibrous mortar. Empirical equations were developed to predict elastic modulus. It was found that ISSBs had reasonable strength to be considered for masonry. The failure load and toughness index of 2% sisal fibre samples was improved by 10% and 16%, respectively, whereas 2.21 times enhancement was found in elastic modulus. Thus, 2% sisal fibre in plaster (i.e. reinforced coating) would likely improve the lateral resistance of interlocked masonry walling.

Interlocking soil blocks are on of modern techniques of house construction due to its durability. The use of these blocks fits suitably within the production cost and environmental quality as an alternative to fired bricks. This paper reports the result investigation done on walls made using interlocking soil blocks. Three types of walls with different combination of reinforcements were tested. The performance is assessed in terms of cracking patterns, failure modes and load-deflection characteristic. Results show that the ductility of all walls are good and wall with post-tensioned bars performed the best. The post tensioned walls are able to deflect up to 42% without any failure compare to non pre stressed wall. The walls with combination of reinforcement and post –tensioned systems are more ductile compare to walls with reinforcement only. It is concluded, post-tensioned wall developed using interlocking soil blocks can be used in reinforced and post-tensioned masonry application instead of conventional brick masonry.
