Abstract
Compressed earth blocks (CEBs) are gaining recognition as an eco-friendly building material. However, the long-term impact of moisture exposure on their structural integrity is uncertain. This study experimentally investigates the variations in compressive strength and fracture characteristics of cement stabilized CEBs under extended immersion periods. CEB samples were subjected to water immersion for 1 – 28 days. Compressive strength tests per IS 3495:1992 were conducted at progressive curing ages. The density, water absorption, compressive strength, failure patterns and accelerated weathering response were evaluated. The results show that compressive strength of both full-sized and half-bat samples increased up to 16 days, reaching 13.64 MPa and 11.03 MPa respectively
Description
The study provides a systematic basis for evaluating long-term performance of CEBs, validating their suitability for durable, sustainable construction. It advances the knowledge on stabilized earthen materials, promoting further research into suitable protection techniques and optimized manufacturing to harness the full potential of CEBs as an eco-friendly building solution
