Influence of sunflower aggregates surface treatments on physical properties and adhesion with a mineral binder

► A new experimental measurement to characterize the adhesion between a solid and a binder paste. ► The determination of specific plant aggregate properties helps to predict adhesion with a binder. ► Water has a major influence on the adhesion process between a plant stem and a mineral binder. ► Lignocellulosic particle treatment can improve adhesion with a mineral binder. ► Interfacial shear stress creation is linked to binder shrinkage.
