QUALITY CONCRETE K-B0 (Nol) K-100, K125, K-150, K-175, and K-200 (Non-structural concrete)
Non-structural concrete is a concrete casting job that does not directly contain structural elements, including iron as a reinforcing material for cast concrete. Non-structural concrete quality or also known as class I concrete.
QUALITY CONCRETE K-225, K-250, K-275 and K-300 (Structural)
Structural concrete is a type of concrete that contains elements of reinforcing iron in the castings, structural concrete also includes ironwork and concrete casting work. Meanwhile, other jobs that are often associated with concrete work are the work of preparing steel structures, concrete formwork, finishing concrete, concrete foundations, masonry and so on.
The quality of structural concrete is also called class II concrete which consists of several grades.
QUALITY CONCRETE K-325, K-350, K-375, K450, and K-500 (Prategang)
Prestressed concrete is a combination of concrete and steel, while concrete is a material that has high compressive strength but low tensile strength. Besides, steel has a very high tensile strength. With the combination of the strength of concrete and steel, it will produce a structure that is strong against compressive loads and tensile loads. This prestressed concrete ready mix quality is also called class III which consists of several class characteristics.
From the sources that we get regarding the quality of this concrete, it can be categorized other than those mentioned above, as for concrete when viewed from its class and quality are as follows:
Class A (K 500)
The purpose and designation of this class is for precast or prestressed concrete
Class P (K450)
This concrete type class is used for rigid, class 1 roads or state nets and toll roads)
Class B (K350)
This type of concrete class is intended for floors, usually the ground floor of a factory building
Class K 300
Concrete for the construction of a house building with 3 to 5 floors
Class K 250
Construction of two-storey building, shop / house / standard.
Klas K 225, K225 Concrete Quality
Klas 225 (MINI MIX / small car), a two-storey building construction, shop / house.
Class D (K 175) lightweight building construction.
Klas E (K 125) construction LC / ground floor
LC construction class BO / ground floor.
