A novel system utilising steel-fibre reinforced concrete (SFRSSC) has been developed and implemented in projects in the recent years for structures such as ground-based slabs and ground-level elevated slabs on piles among others. Being that the system is chemically prestressing the concrete, this compressive self-stress can be used to significantly decrease the thickness of the structures while maintaining their load bearing capacity yet decreasing the materials used and lowering the emissions caused by making the said structures. Recently, a comparative full-scale testing has been conducted to compare the impact of the chemical self-stress on the load bearing capacity of a supposed ground-level slab on piles when looked in a comparison with a more traditional steel fibre reinforced concrete slab in a practically identical situation. This document shall shed light on the possibilities of reducing the CO2 emissions via usage of SFRSSC when compared to other existing more traditional construction systems. The full-scale tests revealed that the SFRSSC slab could bear approximately 30% higher loading while maintaining 30% lower deflections and exhibiting lower number of cracking. This, in turn, allows for making SFRSSC slabs significantly thinner, thus reducing the emissions caused by the extraction of raw materials, transportation of the said materials, production of the concrete and production of the structure itself.
