Volume Stability of Cement Paste Containing Limestone

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

The addition of limestone fines to fill into the voids between aggregate particles can reduce the volume of voids to be filled with cement paste and thus reduce the cement paste volume needed to produce concrete. Apart from decreasing the cement clinker consumption and carbon footprint, this may have other benefits too.
