The tensile strength of concrete is 7–15% of its compressive strength.. Concrete is weak in tension because it contains fine cracks and pores as it contains mixture of aggregate,cement etc..because of which the area resisting the tensile force becomes lesser and so its tension resiting capacity

The tensile strength of concrete is used in combined-stress design. In normal-weight, normal-density concrete the tensile strength can be found from
In this study, the panel span, depth-to-width ratio, and tensile strength of the reinforcement bars incorporated in the lower plank were investigated . The geometric properties of the seven panels studied are provided in Table 1. Three glulam panels with spans of 4 and 6 m were used as reference specimens.

As the knowledge and understanding of different timber species has grown, so too has the use of timber in applications where strength is a key performance criteria.
Tensile strength also depends on the density of the wood: for example, the tensile strength of the spring wood in a pine is only 1/6 of that of summer wood.
Why do concrete have more compressive strength and less tensile . Why is the tensile strength of concrete very . of compressive strength and tensile strength.
ASTM D 1037 and for structural panels in ASTM D 3044. Strength Properties Strength refers to the maximum stress that can be developed in a member due to applied loads prior to failure. Mechani-cal properties most commonly measured and represented as “strength properties” for design include modulus of rupture
The tensile strength of concrete is one of the basic and important properties. Splitting tensile strength test on concrete cylinder is a method to determine the .

Tensile strength in the direction of the grain is usually 10-20 times more than its strength perpendicular to the grain. Tensile strength also depends on the density of the wood: for example, the tensile strength of the spring wood in a pine is only 1/6 of that of summer wood. The compression strength of air-dry wood is about half of the corresponding tensile strength. The shearing strength of wood is 10-15% of its tensile strength in the direction of the grain. Shearing strength is weakened .
