The nodes stick to the crushed rock and sand too and bind these ingredients. This all is a part of the hardening process. At the same time, a great amount of heat increase occurs. Because hydration is an exothermic process. What's cool is, you can measure your concrete's temperature. You'll then know how far along the hydration process is.
