The Sustainability of Low-Rise and Tall Buildings Made with Normal and High Strength Concrete

摘要：

　　To reduce the mass of CO2 released in the atmosphere by the construction industry, the performance strategy can be adopted.It is based on the use of High-Strength Concrete (HSC) in alternative to Normal-Strength Concrete (NSC).Such concretes are herein taken into account to design the reinforced concrete structures of three buildings, having 14, 30 and 60 floors, respectively.For each building, the structural analyses, carried out for four classes of concrete (i.e., C25/30, C40/50, C60/75 and C80/95) in accordance with Eurocode 2, provides different dimensions of the structural elements.In other words, the amount of CO2, released in the atmosphere for the production of the structural materials, is a function of both concrete strength and the height of building.As a result, the minimum impact of low-rise buildings occurs when the structural elements are made with NSC.Conversely, only when HSC is used to build the structural elements of tall buildings, can the mass of CO2 be effectively reduced.
