Influence of sustainable cement alternatives on the design and construction of concrete structures
The aim of this research is to study the influence of using a reduced cement content or sustainable alternative binder on the structural design and construction method of a concrete structure. The main tendency is the reduction of the carbon footprint of a concrete structure. The replacement of clinker in a concrete composition with ground granulated blast-furnace slag (GGBFS) appears to result in a significant reduction of the carbon footprint. Replacing clinker by GGBFS result in lower initial compression strength of the concrete but higher strength development over time. It is presented what the consequences are for the structural design and construction process of a concrete structure.
