Abstract

Engineered Cementitious Composite (ECC) is a unique type of cement mixture that exhibited superior tensile strain-hardening compared to normal fibre reinforced concrete (FRC). ECC contains a mix of cement/fly ash, sand, water, chemical adhesives and a relatively low volume (typically <2%) of short discrete low modulus fibres, such as polyvinyl-Alcohol (PVA) fibre. The interaction between the microfibers and other materials create flat steady state multi-cracking of concrete when under stress. In this paper, an innovative lightweight ECC material is developed by replacing a fraction volume of cement with lightweight hollow glass microsphere additives. It is expected that the material will have a lower density than the normal ECC, better energy absorption and improved compressive strength. Both static testing and impact testing using Split Hopkinson Bar (SHPB) have been conducted.
