Compressive (Crushing) Strength :: MakeItFrom

In the context of refractories, the term cold crushing strength is used for compressive strength measured at room temperature, to highlight the fact that the value does not reflect performance at high temperatures. Compressive strength is almost always cited for ceramic materials, where it is substantially higher than compressive strength.

Cold Crushing Strength (CCS) of Refractory Bricks and

Cold crushing strength (CCS) of a refractory brick represents its strength. That is it tells us how much load that refractory can bear in cold conditions. The concept of testing CCS of a refractory material has perhaps, come from metallurgy. This is because for any refractory brick it is rather; rare that it would fail simply due to load on it

Curing Concrete Normal, Hot and Cold Weather

Concrete that is allowed to dry in air will gain only 50% of the strength of continuously moist-cured concrete. Lack of water also causes the concrete to shrink, which leads to tensile stresses within the concrete. As a result, surface cracking may occur, especially if the stresses develop before the concrete attains adequate tensile strength.
