With concrete being the most widely used construction material globally, Portland cement (PC) manufacture and CO2 emissions are two environmental concerns that go hand in hand: for every tonne of Portland cement produced, approximately 870 kg of CO2 are emitted. On the other hand, the Gulf region is experiencing a growth in construction sector and trends predict even higher future demands for cement production. Replacing, therefore, PC with alternative low carbon cements (LCC) while still achieving performance requirements now becomes a crucial aspect in the emerging of environmental awareness. Prominent examples of LCC that can potentially reduce the embodied CO2 of concrete by more than 70% using the equivalent concrete performance concept are the super-sulfated cements; a cementitious system on which this paper focuses on.
