Optimization of the Mechanical Formulation of Typha Concrete

In order to address energy efficiency issues in the building sector, we conducted this study which focuses on the optimization of the mechanical characteristics of Typha concrete for its use in load-bearing structures of buildings. The fact that buildings are very energy-intensive makes it essential to develop new forms of construction based on bioclimatic architecture and the valorization of certain materials considered as waste in construction. To achieve these objectives, wehave targeted the use of Typha Australis thanks to its great availability and high thermalinsulation capacity. Thus, starting from the composition of a control concrete determined by the Dreux Gorisse formulation method with a characteristic compressive strength of 20 MPaat 28 days, Typha S1 series concretes are formulated with the substitution of sand up to 40, 50,and 60% of Typha. In order to increase the mechanical strength of Typha S1 series concretes, the cement class and G/S ratio are increased for the second S2 series. At the end of this research, the results obtained show that some of these concretes with different proportions of Typha have good mechanical performance, which depends on their structural use.
