Abstract: New forms of building materials have been emerging, where natural fibres (biomass) are used
along with zero emission or low emission pozzolans or binder materials such as lime, fly ash,
furnace slag, etc. to reduce CO2 emissions from construction industry. One such building
material uses Hemp and lime, and is called lime hemp concrete (LHC). This research was
focused on quantifying the already established carbon sequestration capability of LHC by
formulating a LHC mix, manufacturing a test cube and, conducting CHN Elemental analysis
of hemp and X-Ray Diffractometer analysis of binder. The analyses results are computed to
determine the quantity of carbon sequestration. A stoichiometric analysis was conducted on
the functional unit of dimensions 7 × 7 ×7 cm3to establish a predicted carbon sequestrationpotential of 161.3 g of CO2, translating to 470.3 kg of CO2 per m3of LHC. At the age of 28days, it was found that the cube had achieved a carbon sequestration of 105.4 g of CO2,translating to 307.3 kg of CO2 per m3of LHC. It was found that these results were better thanthose published by other researchers. Reasoning for the same and future work have been
discussed in the paper.
