ABSTRACT
High performance fibre reinforced cementitious composites (HPFRCC) have been steadily developed in the last two decades. One of the salient features of HPFRCC is its strain hardening and multiple cracking behaviours in both tension and bending (Naaman & Reinhardt, 2006). It is a short fibre (metallic and/or non-metallic) reinforced cement based composites where fibre content between 2% and 3% by volume appears to be the most attractive due to ease of processing. Great interest in this area is observed through the development of engineered cementitious composites (ECC) (Li & Wu, 1992) and ductile fibre reinforced cementitious composites (DFRCC) (JCI, 2003). Ductile fibre reinforced cementitious composites (DFRCC) is cement based composite reinforced with short random fibres which exhibits deflection-hardening and multiple-cracking behaviours in bending. It is a special class of HPFRCC that has higher deflection capacity than that of regular fibre reinforced concrete (FRC) and exhibit deflection hardening and multiple cracking behaviours. However, current version of DFRCC is limited to cement rich matrix, although the replacement of cement with fly ash is reported in few studies (Ahmed, et al., 2007).
