Experimental investigation of parameters influencing mechanical properties of hemp concretes using design of experiment method

Abstract Global concerns about climate change have led to the development of building materials that use plant biomass with added benefit sequestering carbon from atmosphere. Lightweight concrete made hemp, is a material huge potential in terms its ability achieve hygro-thermal performances close those polystyrene. This ecological material, referred literature as hemp concrete, some components that, depending on chosen combination, can generate different results physic-mechanical properties. The method based series experiments are generated using program called Design Experiments (DoE). uses statistical analysis performed by varying one input parameters, like amount hydrated lime or cement. Following this analysis, it possible identify elements used composition, which produced significant influence physical-mechanical properties concrete. Moreover, also allows quantification influences so parameters be ranked, minimum number experiments. is, same time, modern and an economical technique for experimental planning. aim research quantify numerically each component element mixture determines variations study will contribute future optimization compositions, differentiated basis mechanical performance thermal insulation criteria.
