Abstract:

This study investigates the physical, strength, and durability properties of stabilized earth blocks. The literature generally reported that stabilized earth blocks have lower strength and durability properties than conventional mortar blocks. Based on these, several mitigations or improvement measures have been recommended. Notably, the use of both natural and synthetic and Portland cement have been proven to be the most viable. A holistic review has been carried out on the physical, chemical, mechanical, and durability properties of stabilized earth blocks. Results showed that stabilization of earth blocks resulted in improved strength, volume stability, microstructure, and durability. These enhanced properties have made it suitable for use as a replacement for conventional cement-sand blocks. It was also reported that earth blocks had attained a compressive strength that is two or three times greater than the 4.3 mpa compressive strength of vibrated cement sand blocks. Based on these, it was recommended for structural applications.

Keywords:
