The History of Concrete

For hydration to take place, concrete must have a minimum water-to-cement ratio of 25 parts of water to 100 parts of cement. Water in excess of this ratio is surplus water and helps make the concrete more workable for placing and finishing operations. As concrete dries and hardens, surplus water will evaporate, leaving the concrete surface porous.
