ABSTRACT Sustainable Construction Materials (SCM) are crucial for reducing lifecycle emissions in the built environment, yet their adoption remains limited in many developing economies, such as Nigeria. This study investigates how awareness influences the adoption of SCM among professionals in Nigeria's Architecture, Engineering, and Construction (AEC)

Geopolymer: A Systematic Review of Methodologies
The geopolymer concept has gained wide international attention during the last two decades and is now seen as a potential alternative to ordinary Portland cement; however, before full implementation in the national and international standards, the geopolymer concept requires clarity on the commonly used definitions and mix design methodologies.

Bacterial healing of cracks in metakaolin‐based geopolymer concrete exposed to high temperatures
Abstract This study examined the bacterial healing of metakaolin‐based geopolymer concrete modified with colemanite (K) and red mud (RM) exposed to high temperatures. The metakaolin‐based geopolymer concrete samples modified with 4% K and 6% RM were prepared.
