Admixture for a cementitious material to influence the rheology properties of the cementitious material
The invention relates to an admixture for a cementitious material suitable to influence the rheological properties of the cementitious material. The admixture includes a compound having a backbone chain provided with at least one first functionality and at least one second functionality. The at least one first functionality is adapted to adsorb to the cement particles of the cementitious material. The at least one second functionality is adapted to respond to an external trigger signal of an electric field, a magnetic field or an electromagnetic field, thereby influencing the rheological properties of the cementitious material. The rheological properties are influenced by influencing the interaction of the at least one first functionality with the cement particles and/or by influencing the interparticle interaction between the cement particles. The invention further relates to a cementitious material including such admixture. Furthermore, the invention relates to a method and a system to control or influence the rheological properties of a cementitious material.
