Effect of compressive strength and tensile reinforcement ...
The effect of concrete compressive strength and tensile reinforcement ratio on the flexural behavior of reinforced concrete beams was investigated. Based on the test results, the following conclusions can be drawn: 1. For the same longitudinal reinforcement the cracking moment increases as concrete compressive strength increases. 2.

What is the Importance of a Reinforced Concrete Slab?
Compressive Strength. How Concrete is Strong – The sand and crushed rock in concrete give it compressive strength. The sand and rock in concrete can support tremendous amounts of weight. The harder the rock and the more rock in the mix ratio, the greater the compressive strength of the concrete.

What are the Proper Concrete Mix Proportions? BN Products
2) Adhesion (cement) and compressive strength (rock) are two different factors in the quality of concrete. More cement does not mean more compressive strength; it means more tensile strength. 3) The less water, the stronger the adhesion of cement, but the more difficult it is to work with the concrete.
