**Research**

__Research interests and fundings__

(1) Theoretical analysis and
experimental study on long term durability of cementitious materials and
reinforced concrete structures, including creep, shrinkage, fracture,
freeze/thaw, and alkali-silica reaction of concrete; high temperature damage
and radiation effect on concrete; chemical and moisture transport in concrete;
and chloride-induced corrosion of steel in concrete.

(2) Monitoring and simulation
of long-term performance of reinforced concrete and steel structures. Development of simulation models for
long-term deterioration processes in reinforced concrete structures, installing
sensor network on concrete structures, and integrating simulation models and
sensor network for utilization of monitoring data to calibrate model parameters
in real time.

(3) Evaluation of existing
nuclear power plant structures: containment structures, bioshieldings, and dry
casks. Leakage repair of wellbores in
oil and gas industry, and CO2 underground storage formation. Performance evaluation of protection systems
for highway bridge decks: sealers, thin-bonded overlays, waterproof membranes,
and cathodic protection systems.

(4) Development of
sustainable construction materials for the earth and space construction. Applications of special additives in
concrete, such as carbon nanotubes, optical fibers to make translucent concrete,
forming agents for lightweight concrete, and phase change materials for high
insulation concrete. Develop lunar
construction materials. Optimization of
concrete mix designs. Reutilization of
various solid wastes in concrete such as fly ash, waste glass, waste tires, and
