Development of a Self-Consolidating Engineered Cementitious Composite Employing Electrosteric Dispersion/Stabilization

A self-consolidating engineered cementitious composite (ECC) reinforced with hydrophobic polyethylene fibers has been developed by combining micromechanics based design and rheological design, in a compatible manner. The previously developed micromechanics based design selects material ingredients for tensile ductility in the hardened state. The rheological design, which the focus in this paper, modifies the material ingredients for self-consolidation behavior in the fresh state. The fresh cement paste designed thereby leads to fresh mortar mix with desirable deformability, cohesiveness, and high consistency, and thus satisfies the self-consolidating performance of fresh ECC mix.
