Investigation of the mechanical performance and weathering of hemp concrete
Lime hemp concrete is a sustainable building material that combines hemp shiv and building limes. The construction industry is responsible of the use of non-renewable materials, fossil, fuels, and cement, which produce high emission of carbon dioxide. The aim of this paper is to investigate the effect mix composition and the size of specimen on the mechanical performance and weathering of hemp concrete. The compressive strength 7 days and 28 days of hemp concrete were measured. The results demonstrated that binder content, size of specimens and densities had a significant influence on the compressive strength at both ages. Additionally, the wetting and drying cycles had highlighted the influence of weathering experiments after 10 cycles of testing on mechanical and physical properties of hemp concrete.
