Abstract

Giacomo will talk about his research on functionally layered concrete carried out in Cambridge in collaboration with the Concrete Infrastructure Research Group (CIRG) led by Professor Janet Lees. Cementis the most CO 2 intensive ingredient of concrete, so using it only where it’s strictly necessary and reducing its proportions in concrete mixes works towards reducing its negative impact on the environment The use of cement can be significantly reduced through the innovative concept of functionally layered elements, i e structural components where concrete with high cement content is used rationally only when needed. Giacomo will talk about how the fresh state behaviour of functionally layered elements can be characterized through innovative experiments and predicted through plasticity theory In the second part of his talk, Giacomo will discuss his findings on the hardened state behaviour of layered concrete elements, with particular focus on the bond strength at the interface between layers.
