how does constantly turning cement in a truck keep it from drying out/hardening

171 views

I see cement trucks constantly turning the cement, I get that it may just be keeping it thoroughly mixed so no one part becomes more dried than the rest. Is that all that’s happening here?

The mixing in the truck does have an initial slowing down effect on the start of the curing but the breaking up of the crystalline structure caused can make the final set proceed faster and can also affect the nature and properties of the end product.
