CENTER FOR MULTIFUNCTIONAL NANOCOMPOSITE CONSTRUCTION MATERIALS

Abstract: 

Cementitious materials such as cement paste, mortar and concrete are construction materials widely used all over the world. However, these materials exhibit extremely brittle failure, low tensile capacity and are susceptible to cracking. These characteristics are serious shortcomings that not only impose constraints in structural design, but also affect the long term durability of structures. This proposal is focused on developing new high performance nanocomposites with substantially increased mechanical properties.

Specific objectives of the research are to increase the tensile strength, Young's modulus, toughness, ductility and durability of the cementitious matrix through the use of carbon nanotubes (CNTs), carbon nanofibers (CNFs), Technical Textiles (TTs) or a combination thereof. Additionally, by taking advantage of the excellent electromechanical characteristics of CNTs and CNFs, new multifunctional CNT/cement nanocomposites will be developed, featuring smart properties that would be ideal for non-destructive health monitoring of concrete structures, damage evaluation and traffic monitoring. Similar smart composites will be developed with the use of TTs that incorporate optical fibers.

The main objectives of the work are outlined below:

  1. Development of advanced cementitious nanocomposites reinforced with CNTs/CNFs.
  2. Design and optimization of multifunctional textile reinforced/cementitious composites.
  3. Simulation and study of the failure mechanics of nanocomposites.
  4. Development of multifunctional smart cementitious nanocomposites to be used in non-destructive structural health monitoring.
  5. Development of a new advanced processing method for massive use of CNTs/CNFs admixtures in the concrete industry.

The proposed research is expected to substantially improve the state-of-the-art in the area of fiber reinforced concrete.

The research results will find wide applications in all civil engineering projects of conventional and high strength concretes.
