摘要

The increasing use of compressed earth blocks (CEBs) in construction, driven by their ease of manufacturing and environmental sustainability, presents a significant advantage in the building industry. However, the lower compressive strength of these blocks compared to traditional ones requires innovative approaches to enhance their load-bearing capacity. This study focuses on investigating the impact of incorporating reinforcing steel bars and grout material in CEBs walls to strengthen their structural integrity by creating Micro Columns (MC) within the walls. The research aims to determine the percentage of participation of these elements and establish the required spacing between the columns for optimal load resistance. The study reveals that MC contribute to resisting vertical loads on the wall buildings at a rate of approximately 58% of the total wall strength. The optimal distribution of MC was achieved when using a spacing distance between the columns equal to 1 m per wall length.
