AB  - Compressed Earth Blocks (CEB) are produced
utilizing stabilizing materials to obtain suitable endurance
and strength to make proper construction material. Those
blocks would be an excellent option for cities and rural
areas where gypsum soil is available in abundance. This
research paper includes an experimental investigation to
find the ability to produce CEB from locally available
gypsum soil by using chemical and physical. The effect of
using cement as a chemical stabilizer at different cement
to soil content with various water mixing content on CEB
physical and mechanical properties including compressive
strength, water absorption, dry shrinkage and elasticity
was studied. The properties of the blocks were carefully
examined. The study showed adding ordinary Portland
cement to gypsum soil to produce CEB affected its
properties by significant increasing. The compressive
strength by 30.3% and reducing water absorption by 5.6.
Moreover, the dry shrinkage of the blocks was decreased
by 35% and the highest rate of shrinking was recorded in
the first 3 days and stopped at 14 days. Finally, CEB
showed a significant improvement in elasticity when
increasing the cement content in the mix.
