Types of concrete. Concrete broadly falls into four categories: standard prescribed concrete (SPC), designated concrete, designed concrete and proprietary concrete. There are different types of concrete grades: Designated concretes. General concrete: GEN0 | GEN1 | GEN2 | GEN3. Reinforced concrete: RC20/25 | RC25/30 | RC28/35 | RC32/40 |
