A class A splice is defined in ACI 318 Section 12.15. There are two types of splice (A and B) which define the length of the splice as a multiple of the tensile development length (ld) Class A denotes a splice that has 1.0 x ld of overlap. A class B splice has 1.3 x ld. Class B is required except where splices are kept out of critical ares (see the code).
what is the purpose of reinforcing bars in a spread footing
what is the concrete ratio in Class D2 concrete
class in which objects can be created is called as concrete class.
The weight can only be determined if the exact weight of the reinforcement, as well as the exact displacement of the reinforcing is known. Thus the weight should be 1 sq meter x thickness of the concrete minus the exact displacement of the reinforcing, plus the weight of the reinforcing. The weight per cubic meter of concrete is 2450 kg.

Class A and Class B splices in rebar refer to different methods of connecting reinforcing bars to ensure structural integrity. Class A splice is a lap splice where the bars overlap for a specified length, allowing for the transfer of stress between them. Class B splice is a mechanical splice that uses connectors to join the bars end-to-end, providing a stronger and more reliable connection. Both types are governed by specific codes and standards to ensure safety and performance in construction.
Post tensioning is the prestressing of a concrete member by tensioning the reinforcing tendons after the concrete has set

As I would interpret the question, I would refer to the nature of reinforcing to be placed within the concrete. Often in large beams, the reinforcing steel may be made up separately in "cages" and set in place for the concrete pour. The reinforcing may be comprised of shear, bending, torsional, and specialized support components.

concrete, probably with steel reinforcing
François Coignet in France
Concrete is usually reinforced by adding steel. The cost of reinforcing concrete depends with the given area under which the steel is placed to reinforce it.
