    Abstract. The paper considers the initial proposals for determining the distance between cracks in a centrally tensioned reinforced concrete prism, which formed the basis for a similar technique for determining the distance between normal cracks during beam bending in a state of pure bending. The impossibility of the absence of adhesion stresses between reinforcement and concrete in the presence of longitudinal stresses in the reinforcement and provided adhesion is considered and proven from various positions. A comparison of experimental approaches to studying the problems considered in the theories of adhesion and crack resistance is performed. The impossibility of using the technical theory of adhesion to determine the distance between primary normal cracks is substantiated. Based on the results of the analysis, the impossibility of theoretically determining the distance between cracks in a centrally tensioned reinforced concrete prism is recorded. An analogy is drawn between the modulus of elasticity of concrete or reinforcement and the distance between normal cracks, which complements the main mechanical characteristics of reinforced concrete.
    Keywords: tensioned reinforced concrete prisms, stresses of adhesion of reinforcement to concrete, crack formation, crack pitch, distance between cracks
