Traditionally, the use of limestone fines (LF) in concrete is to replace either part of the cement or part of the fine aggregate, notwithstanding this, the authors are advocating that the LF should be better used as cement paste replacement, which is expected to improve the durability and sustainability of concrete at the same time. To verify this new strategy of using LF, 9 nos. concrete mixes of the same powder paste volume ratio and variable LF contents and W/C ratios were produced for permeability and strength measurement. The results proved that the strategy of using LF to partially replace cement paste could effectively decrease the permeability and increase the strength at the same W/C ratio. Furthermore, even when the W/C ratio is allowed to slightly increase while keeping the concrete at the same strength, the permeability can also be significantly reduced for better durability by using LF as cement paste replacement.
