Effects of Low-Carbon Binders on the Mechanical and Thermal Properties of Biobased Insulation Materials
The impact of climate change has prompted government authorities to implement regulations aimed at reducing energy consumption and CO2 emissions. The construction industry holds a prominent position among the major greenhouse gas emitters, contributing a large amount of global energy consumption. A significant portion of these emissions is attributed to heating. In response to these challenges, the use of biobased materials emerges as a solution. In this context, this study aims to assess the impact of low-carbon binders on the mechanical and thermal properties of biobased insulation materials. Binders such as natural prompt cement and natural air lime CAEB CL 90-S are considered sustainable, low-carbon alternatives. The results highlight that hempcrete (cement/hemp) exhibits enhanced mechanical strength with a 0.80 MPa at 28 days and low thermal conductivity with a value of 0.12 W/(m·k). In comparison, hempcrete with lime exhibits lower mechanical strength (0.4 MPa) and thermal conductivity (0.20 W/(m·k)) at 28 days and flax shives with both binders. In a parallel manner, it is observed that the compressive strength of flax shives, when combined with both binders, is inferior to that of cement/hemp. Simultaneously, the thermal conductivity of flax shives with both binders surpasses that of cement/hemp.
