    classes of concrete Everything About Concrete

    When going through building plans I encounter construction jargon where I am instructed to cast class 25, 20 or 30 of concrete. What are these classes and how do I determine them where not given? The grade 15, 25, 30 means the concrete compression resistance(or strength) at 28 days.

    Constructing a Mat Slab| Concrete Construction Magazine ...

    Jan 18, 2006· The heat generated by the hydration of cementitious materials causes temperatures in the center of a slab to be much higher than at its surfaces. This temperature gradient is the critical thing to remember about mass concrete since it can cause thermal cracking that would compromise the structural strength of the slab.
