A higher modular ratio shows A. Higher compressive strength of concrete B. Lower compressive strength of concrete C. Higher tensile strength of steel D. Lower tensile strength of steel

The correct answer is: A higher modular ratio shows higher tensile strength of steel.

The modular ratio is a dimensionless number that is used to compare the stiffness of concrete and steel. It is calculated by dividing the modulus of elasticity of steel by the modulus of elasticity of concrete. A higher modular ratio indicates that steel is stiffer than concrete.

Tensile strength is the ability of a material to resist being pulled apart. Steel has a much higher tensile strength than concrete. This is why steel is often used as reinforcement in concrete structures. The steel reinforcement helps to resist the tensile stresses that are generated in the concrete when it is loaded.

The following are the brief explanations of each option:

• Option A: A higher modular ratio does not show higher compressive strength of concrete. The compressive strength of concrete is the ability of concrete to resist being compressed. It is measured in pounds per square inch (psi). The compressive strength of concrete is affected by the type of cement, the water-to-cement ratio, the aggregate type and size, and the curing conditions.
• Option B: A higher modular ratio does not show lower compressive strength of concrete. The compressive strength of concrete is the ability of concrete to resist being compressed. It is measured in pounds per square inch (psi). The compressive strength of concrete is affected by the type of cement, the water-to-cement ratio, the aggregate type and size, and the curing conditions.
• Option C: A higher modular ratio does show higher tensile strength of steel. The tensile strength of steel is the ability of steel to resist being pulled apart. It is measured in pounds per square inch (psi). The tensile strength of steel is affected by the type of steel, the heat treatment, and the manufacturing process.
• Option D: A higher modular ratio does not show lower tensile strength of steel. The tensile strength of steel is the ability of steel to resist being pulled apart. It is measured in pounds per square inch (psi). The tensile strength of steel is affected by the type of steel, the heat treatment, and the manufacturing process.
