Abstract

The paper describes a new, cheaper water-reducing compound obtained from cashew nut shell liquid (CNSL). The properties of mortars, namely flow, setting time and compressive strength, were determined in the presence of 0.1 to 1.0% superplasticizer. The compressive strength of mortar containing the superplasticizer from CNSL was higher than that of the control

Resume

On décrit un réducteur d'eau meilleur marché obtenu à partir d'extrait de coquilles de noix de cajou (CNSL). On examine les propriétés des mortiers: écoulement, temps de prise et résistance à la compression en présence de 0,1 à 1,0% de fluidifiant. La résistance à la compression du mortier contenant le fluidifiant est plus élevée que celle du mortier de contrôle.
