Fresh concrete does not simply dry into a hard mass. It becomes strong through hydration: chemical reactions between cement and water.
A reaction that outlasts the pour
As water reaches unreacted cement grains, new structures form and bind aggregate together. The process slows over time but can continue well beyond the first few days.
Why curing matters
Keeping young concrete moist supports hydration and limits early shrinkage. That is why careful curing matters even after the surface appears hard.
