A second objective was to minimize the amount of cement in alternative materials. It was possible to reduce and limit the amount of cement by replacing a quantity of cement by WSA in respect with the mechanical resistance required. It is also possible to co-valorize WSA and some other waste agriculture by-products such as natural fibers i.e. hemp and flax shives (Zmamou, 2015).

In concrete and mortars, fibers are used to provide cracking control at early ages and increase fracture strength [26]. Natural fibers and shives are also used for insulation purposes. Hemp fibers and shives give a quite low value of thermal conductivity (0.2 W/(m·K)) [27] to a mineral matrix based on lime [28] or cement [29]. Also, wood shavings into a sand–cement mixture increase the total porosity of mortars with a consequent increase in thermal insulating properties [30].
