Optimization of multi-component cements containing clinker, slag, V-fly ash, limestone
- The aim of this study was to investigate the optimization of the strength development of quaternary cements with 50 % clinker by a variation of the particle size distribution of the components GGBFS, fly ash and limestone powder.
By balancing the overall PSD of the cement by using unprocessed fly ash and coarse limestone powder in combination with a very fine GGBFS, the water demand of theThe aim of this study was to investigate the optimization of the strength development of quaternary cements with 50 % clinker by a variation of the particle size distribution of the components GGBFS, fly ash and limestone powder.
By balancing the overall PSD of the cement by using unprocessed fly ash and coarse limestone powder in combination with a very fine GGBFS, the water demand of the resulting quaternary cements remained unaltered, while the compressive strength of the cements was increased significantly after 7d, 28 and 56d. As can be expected, the quaternary cement with 30 wt.% of the fine slag exhibited a stronger strength increase (about 18 % after 28 d) than the cements with only 20 wt.% slag (about 10% after 28d).…
