A comprehensive review on the properties of hemp incorporated concrete: An approach to low carbon footprint construction

Abstract

As the demand for sustainable construction materials rises, hemp-infused concrete has emerged as a promising solution to reduce carbon emissions and promote eco-friendly building practices. This review critically assesses hemp concrete's mechanical, thermal, and durability properties, highlighting its potential for widespread adoption in various industries. Hemp's porous structure contributes to improved thermal insulation, soundproofing, and biological resistance, making it suitable for in-fill materials, plastering, and insulation applications. However, its low compressive and flexural strength remains challenging, limiting mainstream use. Hemp content and composition variations have resulted in differing properties, necessitating further research to optimize the material. The study identifies the growing collaboration among countries to promote bio-based materials but acknowledges the lack of standardized norms for hemp concrete in general construction. It stresses the importance of developing uniform standards to ensure consistent quality, performance, and regulatory compliance. This study explores the properties of hemp-infused concrete. It assesses its potential as a sustainable building material while identifying gaps in research and standardization needed for its widespread adoption in the construction industry.
