Nowadays limestone powder and blast furnace slag (BFS) are widely used in concrete as blended materials in cement. The replacement of Portland cement by limestone powder and BFS can lower the cost and enhance the greenness of concrete, since the production of these two materials needs less energy and causes less CO2 …

More interesting is the effect of fillers in BFS cement-based mixes: they induce a slight decrease of the initial time dormant period, which could be attributed to the formation of carboaluminates that accelerate the setting [2], [21] but also the so-called "nucleation effect" of the small limestone particles. This effect may contribute to ...

The common cause of cracking in cement paste is shrinkage due to different reasons, such as loss of water and chemical reactions. Incorporating limestone fines (LF) as a cement replacement can affect the shrinkage of the paste. To examine this effect, five paste mixes were prepared with 0, 5, 10, 15 and 20% LF as a cement replacement and …
