This study proposes a novel low carbon cementitious two stage layered fibrous concrete (LCCTSLFC) derived from clinker, flyash, calcined clay and steel fibres. In two stage fibre reinforced concrete (TSFRC), the volume of steel fibres together with coarse aggregates are pre-mixed and pre-placed into the mold. Henceforth, filling of voids in-between the aggregates is done by grouting that flows through gravity. The short and long steel fibres used throughout the thickness (layered), manufactured low carbon cement, X-ray diffraction (XRD) and scanning electron microscope (SEM) analysis were considered here in. For the first time, this research develops the concept of impact resistance of LCCTSLFC under falling weight collision. For this purpose, short crimped fibres and long hooked end steel fibres were used in two stage layered concrete and tested as per ACI committee 544 guidelines. The results reveal that the proposed layered LCCTSLFC specimen shows superior impact strength compared to that of fully reinforced cross-section with equivalent dosages of fibre. This study emphasizes the potential to engineer a new layered LCCTSLFC with superior compressive and impact strength properties for the safety of civil and military infrastructure during terrorist attacks. © 2019 Elsevier Ltd
