Abstract
The developed study aimed at investigating the mechanical behavior of a new type of self-insulating concrete masonry unit (SCMU). A total of 12 full-grouted wall assemblages were prepared and tested for compression and shear strength. In addition, different axial stress ratios were used in shear tests. Furthermore, numerical models were developed to predict the behavior of grouted specimens using simplified micro-modeling technique. The mortar joints were modeled with zero thickness and their behavior was applied using the traction–separation model of the cohesive element. The experimental results revealed that the shear resistance increases as the level of precompression increases. A good agreement between the experimental results and numerical models was observed. It was concluded that the proposed models can be used to deduct the general behavior of grouted specimens.

Summary
Masonry has been used as a common building material worldwide for many centuries. Masonry is a composite of block units bonded together with mortar. Inserting insulation material such into normal-weight concrete with special configuration concrete masonry (CMUs) as EPSMost of the previous researches focusaon lightweight concrete of masonry units as goodunits thermal leads an increase in their thermal resistance without affecting their mechanical performance toinsulation materials in buildings This is because they have a lower thermal conductivity compared [13]. Type of unreinforced masonry offers significant contribution units (CMUs) leads to an increase in their thermal resistance without affecting their mechanical regarding the design and construction of cost-effective buildings in seismic regions [14]. Would besignificant applicable for without concern for thermal bridges This concrete type of unreinforced masonry system offers both low and medium height residential buildings in seismic area zones. A comprehensive testing program was carried out to determine the compressive strength and strength
