How does one obtain design strength of concrete = 0.45fck as given in IS456:2000??? Here is the explanation: In india, we test concrete cubes to determine 28-days characteristic strength of concrete, which is depicted by “fck” However, we all know that, if we cast cylinder from the same concrete mix,…

Under Reinforced Sections
Under Reinforced Sections: Prior to describing these sections, let’s establish some fundamental concepts. It is commonly understood that Concrete is robust in compression but feeble in tension, whereas Steel has equivalent strength in both tension and compression. However, when referring to compression in steel sections, there is a concern regarding…
Compressive Strength of Concrete
Compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to which withstands loads tending to elongate. In other words, compressive strength resists being pushed together, whereas tensile strength resists tension (being pulled apart). In the study of…
