Latest Patents

Soltan’s patent, “Self-Reinforced Cementitious Composite Compositions for Building-Scale Three Dimensional (3D) Printing,” describes printable cementitious compositions that are flowable and extrudable when fresh and strain-hardening after they harden. One variation specifies a uniaxial tensile strength of at least about 2.5 MPa, a tensile strain capacity of at least about 1%, and a compressive strength of at least about 20 MPa after 100 hours.

The compositions may include Portland cement, calcium aluminate cement, fine aggregate, water, a high-range water-reducing agent, and polymeric fiber. Optional ingredients include fly ash, silica flour, microsilica, attapulgite nanoclay, and hydroxypropylmethyl cellulose. The patent also describes additive-manufacturing methods using these materials.

Career Highlights

Soltan’s listed patent reflects research into cement-based materials that combine printability in the fresh state with strain-hardening performance after curing. These properties are relevant to additive manufacturing methods intended for construction at building scale.

Collaborations

The supplied information identifies the University of Michigan as Soltan’s company affiliation and Victor C. Li as a coworker. The patent’s subject matter aligns with research in cementitious composites and construction-scale 3D printing.

Conclusion

Daniel G. Soltan’s listed patent focuses on printable, strain-hardening cementitious composites and methods for using them in building-scale 3D printing.
