Green construction materials

The demand for green construction materials is spurred by increased regulations to reduce carbon footprint, limit greenhouse gas emissions, and other environmental problems.  The exploitation of natural resources is growing rapidly to reduce energy consumption and minimize the impact on the environment. 

1.  Natural materials (bamboo & wood)

        Natural fiber with lightweight, high strength, renewability, biodegradability, and environmentally friendly has attracted significant attention.  The sustainability of natural             fiber-reinforced composites has led to upsurge its applications in engineering.

        b） Combustion kinetics of natural plant

2.  Green concrete with recycled waste

The development of green concrete using plastic waste is essential to the construction and the plastic recycling industries.  More than 30% of carbon dioxide is expected to be reduced by using green concrete.  The utilization of solid waste in concrete has become an attractive alternative as the tensile strength, and fracture toughness of such kind of concrete can be improved.

Interface of heterogeneous materials

Interface plays a vital role in determining heterogenous materials' overall mechanical properties.  Comprehensive understanding is required of the complex processes that control interface formation, evolution, and failure.  Scientific insights that guide the design of interface and associated interphases can improve the performance of heterogeneous materials.
