Abstract

Geopolymers have drawn much interest in sustainable building because of their exceptional mechanical strength, longevity, chemical resistance, and less environmental impact.  Using less mortar and requiring less labour, Interlocking Pressed Earth Stabilized Blocks (IPESB) provide increased structural integrity, quicker construction, and cost savings.  This research investigates the creation of Interlocking Geopolymer Mud Blocks (IGMB) using fly ash, ground granulated blast furnace slag (GGBS), M-sand and red soil as essential components. The investigation of IGMB's characteristics included its mechanical and thermal aspects alongside microstructural and physical properties because it incorporated local aluminosilicate sources (ASS) and alkaline-activated materials (AAM) with fly ash and GGBS to substantially boost strength levels.  The material received its characterization through Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and Transmission Electron Microscopy (TEM).  Research indicates IGMB showed superior results against traditional IPESB through its remarkable 5–6 multiple enhancement which delivered excellent compressive strength of 48.45 N/mm².  The strength performance of IGMB was enhanced when AAM solution concentration increased from 8M to 12M showing promise for long-term earthquake protection of this potential building material. Research indicates that IGMB serves as a promising eco-friendly alternative to traditional masonry units, offering both enduring structural stability and environmental benefits.
