  • How to Rapidly Speed up Concrete Drying Time - Concrete ...

    While a lower measure of water in the concrete mix sounds like an obvious solution, low water-cement ratio mixes typically have fewer capillaries – the natural pathways that allow water to move through the slab to the surface. Therefore, even with the reduced amounts of water, slower drying time can result.
