The present invention relates to a process of fabricating a multi-layer composite structure by 3D printing, said composite structure comprises at least one cured mortar layer formed by curing of a mortar composition, and at least one polyurethane layer formed by polymerization of a first polyurethane forming composition, wherein said mortar composition and said first polyurethane forming composition are dispensed individually and simultaneously via adjacent printing nozzles. The mortar composition is optionally modified by a second polyurethane forming composition.

One-step formation of an integrated composite structure comprising cured mortar layers and a polyurethane layer by 3D printing

The invention relates to a multi-component composition for the manufacture of polyurethane/urea cementitious hybrid system, comprising at least one isocyanate component selected from the group consisting of monoisocyanate, polyisocyanate and NCO terminated prepolymer, at least one polyol, water, catalyst, at least one acidic additive, and hydraulic binder, wherein the acidic additive is at least one selected from the group consisting of Lewis acids, acid precursors and acidic buffers and is in an amount of 0.01 to 3 wt %, based on the total weight of the composition, to the preparation thereof, and to the use of the composition for the preparation of a flooring, waterproofing, screed, grouting, primer, wall paint, roofing or coating in construction applications.

Multi-component composition for manufacturing polyurethane/urea cementitious hybrid systems
