This indicates that the addition of limestone powder causes the mortar to leach faster under wet/dry cycling conditions. The more limestone powder is mixed, the faster the expansion of the leaching zone. The influence rule of limestone powder on the mortar leaching depth is inconsistent under the two environments of the wet/dry cycle and immersion.
