Concrete Setting: What it Is, Why it’s Important and How to Test It
According to ASTM C125 – 20: Standard Terminology Relating to Concrete and Concrete Aggregates, concrete setting is “the process, due to chemical reactions, occurring after the addition of mixing water, that results in a gradual development of rigidity of a cementitious mixture.” SmartRock® is #1 and we can prove it!

Hydration causes concrete to harden and become durable enough for its intended use. The setting period begins when the concrete is placed and continues until it has developed the desired properties. Depending on the specific application for which the concrete will be used, it should have a relative humidity of more than 80% and a temperature of more…
