01 Fiber Reinfoced Cementitious Composites
01 Fiber Reinfoced Cementitious Composites
We specialize in the design, fabrication, and experimental characterization of fiber reinforced cementitious composites (FRCCs) — advanced cement-based materials engineered for superior tensile resistance, ductility, and energy absorption under both static and dynamic loading. By optimizing fiber geometry, matrix composition, and fiber-matrix interfacial bonding, we develop strain-hardening composites that exhibit multiple cracking behavior and exceptional impact resistance.

02 Auxetic-Meta Concrete
We specialize in the design, fabrication, and experimental characterization of auxetic meta-concrete (AMC) — cement-based metamaterials engineered to exhibit negative Poisson's ratio behavior. By tailoring meso-scale geometry and leveraging ultra-high-performance fiber-reinforced concrete (UHPFRC), we develop optimized unit-cell configurations that unlock superior deformation capacity and energy absorption.

03 Cement Hydration Simulation
03 Cement Hydration Simulation
We specialize in the simulation of hydration for cement, low-carbon cement, and non-cement. By using an-open scource CEMHYD3D, we sucessfully simulate the hydration of normal cement. Currently, we develop an efficive tool namely AAMHyd3D to simulate the hydration of CaO-activated ground granulated blast-furnace slag, contributing to climate change mitigation and achieving the global goal of net-zero CO2 emissions.
