This course is designed to expand your knowledge. in this course you will learn almost everything about concrete. Concrete is the most used material in construction worldwide. We can find concrete almost in everything around us. Therefore, we need to understand the properties and behavior of this material and what the reason behind using it intensively in construction. Concrete is a durable and it live for a long time. That's why it is preferred in construction of house and building. In this course, we will study the different ingredients of concrete. Also, I will explain the admixture and how various admixtures can alter concrete properties. Recently the using of pozzolans increased sharply, adding of pozzolans to the concrete mix will enhance concrete properties. We will discuss the different type of pozzolans and their effects on concrete. Also, in this course, you gain knowledge regarding SCC and fiber reinforced concrete.Concrete is very good in compression and poor in tension. Concrete will crack when tensile forces applied to a unreinforced concrete. Therefore, concrete cant survives without adding reinforcement. Reinforcing steel is very good at tension. So in order to reduce concrete cracks and resist tensile stresses, steel is added to concrete members. Here I will explain the reason behind reinforcing concrete and the grades and types of rebar. Also, we will discuss cracks in concrete and the prevention and repairing methods. The prestressing of concrete is relatively new. Here we will discuss the concept of concrete prestressing, the different between post-tensioning and pretention and the benefits of concrete prestressing.
