Behavior Of Low-Cost Cci Brick Prisms Subjected To Axial Cyclic Compression And Lateral Forces

Abstract

This study focuses on CCI brick walls, which use minimal mortar and are designed to withstand axial and lateral forces. It investigates how CCI brick prisms respond to cyclic axial loading and explores their bond strength for withstanding lateral loads. The study accounts for regional soil variations in Thailand by using bricks from different areas. The results show consistent behavior in cyclic loading and an increasing load capacity until failure. Reinforced specimens with steel bars outperform those with grout only and the unaltered specimens. Combining cement-sand grout and steel bar reinforcement leads to significant improvements in compressive strength, particularly in smaller and larger height specimens. Non-shrink Cement Sand Grouts exhibit superior bond strength over Ordinary Portland Cement Sand Grouts, and CCI bricks from region 2, known for their higher compressive strength and larger grooves, demonstrate the highest bond strength. The findings emphasize the importance of groove depth in determining bond strength in CCI brick prisms.
