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

Characteristics of cement that affect compressive strength

The compressive strength of cement is principally affected by the relative content of lime (CaO) and the fineness More lime in the composition of portland cement means more of the C 3 S phase which provides higher early strength at a given fineness compared to the C 2 S phase Also greater fineness for the same lime content indicates higher
