why do we provide steel in concrete? | why is concrete weak in tension and strong in compression?

Download our android app for job oriented courses https://clpsheldon.page.link/x3kb In this article, I’m going to address some important questions which come to our mind regarding concrete technology these questions are; Why do we need to provide reinforcement in concrete and why do we prefer steel as a reinforcement? Why is concrete weak in tension and what makes the concrete very strong in compression? I’m also going to discuss the various properties of steel and at the end, I will introduce you to the coefficient of thermal expansion along with a numerical and the factors affecting the coefficient of thermal expansion. quantity surveying topics compiled PDF part 1 👇🏻👇🏻 https://imojo.in/2NE9ex Quantity surveying topics compiled PDF Part 2 👇🏻👇🏻 https://imojo.in/quantitysurvey2 2nd channel 👇🏻 https://www.youtube.com/Civiltutorofficial #ErMuyeenMubarak #civiltutor #concrete technology #civilengineering To make it easy for you, let’s discuss a little bit about the mechanics of materials. i.e, how materials behave under stress. Stress in this case refers to mechanical stress. i.e, the internal resistance offered by the body to the external load applied to it. There are 3 types of stresses: Compressive stress (Pushing together), Tensile stress (pulling apart), and shear stress (sliding along a line or plane). It has been observed that not all materials can take each type of stress equally. If we talk about concrete, it’s very strong in compression and very weak in tension.
