Comparative Study Of Mortarless Interlocking Block Masonry In An Energy-Efficient Structure

ICRTME25-153 Comparative Study Of Mortarless Interlocking Block
Masonry In An Energy-Efficient Structure

ABSTRACT
This research investigates the structural and economic viability of mortar less interlocking
block masonry systems as sustainable alternatives to conventional construction materials. The
study comprehensively examines the mechanical properties, cost-effectiveness, and
environmental impact of interlocking concrete blocks through experimental testing and
comparative analysis. Laboratory investigations were conducted to determine fundamental
material properties including compressive strength, water absorption, density, and
dimensional characteristics, according to established Indian Standards. Masonry prism tests
revealed an average compressive strength of 1.698 MPa with a modulus of elasticity reaching
3842.1 MPa, indicating superior stiffness compared to traditional masonry systems.
Economic analysis demonstrated significant cost reductions when employing interlocking
blocks, while embodied energy calculations showed environmental benefits with 4.92 MJ per
block. The masonry efficiency achieved was 20.96%, comparable to conventional brick
construction but with enhanced ease of assembly. Results indicate that interlocking block
systems offer promising solutions for sustainable construction, particularly in applications
requiring rapid assembly, reduced skilled labour, and improved thermal performance.
