Research: Evaluating Mechanical Performance and Carbon Sequestration of Geopolymer and ...

Research question: How do geopolymer concretes and CO2-cured cement alternatives compare in mechanical properties and net carbon footprint under realistic curing and service conditions?

Background & Motivation: Concrete is the most widely used construction material but is a major contributor to global CO2 emissions. Advances in sustainable materials focus on geopolymer binders and carbon dioxide-curing techniques to reduce the environmental impact of cement production and use.

Research Gap: While both geopolymer and CO2-cured cement alternatives offer carbon-negative potential, there is limited comparative research on their mechanical behavior, durability, and total carbon sequestration in practical applications.

Approach & Expected Contribution: This study will review the literature, formulate testable hypotheses, design laboratory experiments to measure compressive strength, durability, and carbon uptake, and analyze results using statistical methods. The project aims to provide a quantitative comparison, identifying trade-offs and optimal scenarios for deployment.

Significance: Results could inform material selection for low-carbon infrastructure, support policy and specification development, and advance sustainable construction practices by clarifying performance and environmental benefits of these emerging materials.
