CLASSES OF READY MIXED CONCRETE
Classification in TS EN 206-1 ready mixed concrete standard; Environmental effect classes according to the exposed circumstances, density classes, the largest aggregate grain classes, pressure resistance classes and classes according to intensity. The most known and used pressure resistance classes are as follows.
