Project description

A major construction equipment manufacturer had developed several formulations of a so-called macro-defect free concrete. This material is unlike any cement-based material currently available. In fact, the material is much more closely related to various types of rubber - although with vastly different properties than rubber. Although initial basic material property testing has been promising, there is a significant lack in knowledge of what exactly it "is" and what it "isn't". The goal of the project will be to assess important material characteristics and to develop conceptual uses for the material with a specific focus on accelerated/robotic bridge construction.
