FIND A LOCATION We're Hiring Frequently Asked Questions Frequently Asked Questions What makes concrete harden? When cement, sand, stone, and water are combined, a chemical process called hydration occurs in the cement particles. In hydration, the cement particles develop finger-like extensions which become interlocked with other nearby cement particles much like Velcro balls sticking together. These hydrating particles also bond to the sand and stone increasing strength. The amount of water and cement in the mix determines how close these cement particles are together which gives a good indicator of the strength (water/cement ratio). As these components all bond together, moisture is pushed out and evaporates leaving hard concrete in its place. What is plastic shrinkage cracking? What causes plastic shrinkage cracking?
