cement bond bcrusher Bond of Reinforcement in HighStrength Concrete lap splices in highstrength concrete and the applicability of the restriction in the ACI 318 code where the values of √f c′ used to calculate development length shall not exceed 100 psi.

Compressive and Tensile Strength of Concrete: Relation ...The theoretical compressive strength of concrete is eight times larger than its tensile strength. This implies a fixed relation between the compressive and tensile strength of concrete. In fact there is a close relation but not a direct proportionality. The ratio of tensile to compressive strength is lower for higher compressive strengths.
