Concrete Durability Aspects - Concrete Durability: Innovative Materials and Influences of Material Composition
Sažetak
There are now several initiatives to reduce the carbon footprint of cement production, such as the use of alternative binders for clinker. However, reducing the carbon emissions of the cement sector will only be possible when design optimization is combined with other measures. The construction industry is reluctant to reduce the cement content of concrete mixes and is not encouraged to use performance-based design for concrete. In most cases, these steps will negate the benefits of using alternative binders in concrete. The objective of this paper is to investigate the effects of lowering the cement content and additionally substituting part of the cement on the mechanical properties and durability of concrete. The reference mix was taken from a real bridge recently built in Croatia, and the alternative combination was prepared with a reduced cement content of 22%. All mixes were evaluated based on their mechanical strength and resistance to chloride penetration. The carbon footprint of each mix was also studied. The study concluded that the alternative mix with lower cement content had comparable durability and a significantly lower carbon footprint, meaning that the alternative mix proved to be a more sustainable option.
