Kavishan Ranatunga: From Volcano to Concrete: New Zealand Pumice for Low-Carbon Concrete Kavishan Ranatunga (15947264) Construction materials Cement replacement Sustainability New Zealand Natural pozzolan Durability Volcanic materials <p dir="ltr">The image illustrates the journey of New Zealand volcanic pumice from its natural geological source to low-carbon and durable concrete. It highlights the unique porous microstructure of pumice and its potential to partially replace cement, contributing to efforts to reduce greenhouse gas emissions associated with cement production. The artwork combines real images captured during the research with AI-assisted visual modifications to communicate this journey.<br>Kavishan Ranatunga is a PhD student exploring the potential of New Zealand volcanic pumice for sustainable concrete.<br>Kavishan Ranatunga | kran503@aucklanduni.ac.nz</p> 2026-09-30T20:30:28Z Image Figure 10.17608/k6.auckland.34012755.v2 https://figshare.com/articles/figure/From_Volcano_to_Concrete_New_Zealand_Pumice_for_Low-Carbon_Concrete/34012755 CC BY 4.0
