WebMay 26, 2024 · Concrete strength includes compressive, tensile, shear, bending, folding and grip. In addition, concrete grade is classified by the standard value of the compressive strength of concrete cubes. Factors that affect concrete strength are mainly the grade of cement and water-cement ratio, aggregate, age, curing temperature, and humidity. Concrete has relatively high compressive strength (resists breaking, when squeezed), but significantly lower tensile strength (vulnerable to breaking, when pulled apart). The compressive strength is typically controlled with the ratio of water to cement when forming the concrete, and tensile strength is increased by additives, typically steel, to create reinforced concrete. In other words we can say concrete is made up of sand (which is a fine aggregate), ballast (which is a c…
