The water/cement ratio: a fragile relationship

The higher the water/cement ratio, the more porous the concrete and, consequently, the less durable it is. Conversely, with a lower water/cement ratio, the less porous the concrete, and the more durable it is. Conclusion: better to hold off. Like with any relationship, the water/cement ratio is complex .get price
