Civil Engineering: Basics of construction works

Description:

This course designed to expand your practical side of engineering knowledge. This concentrating on various constructions fileds.
firstly, This course is concentrating on the construction of roads. Here you will learn how the road constructed. The construction stages such as protection of existing services, clearing the area, future utilities, preparing the road subgrade, then placing different pavement layers such as sub-base, base course, and asphaltic courses. Also, we will discuss the types of asphaltic course and the common defects of asphaltic pavement, such as permanent deformation, fatigue cracking, and low-temperature cracking. Also, I will show a typical cross-section of road and road profiles.
Also, I will explain what the prime coat is, why the prime coat is used, and the proper way of applying, preparing the surface of the pavement layer before applying the prime coat, and the curing time for a prime coat. Tack coat, what is the Tack coat, why the Tack coat used, where the tack coat is used, and the proper way of applying of tack coat.
This course will explain the process of placing the various pavement layers, spreading of these layers, compacting then testing of the laid layers. Each layer will be tested to determine the in-situ density, level, thickness, and surface smoothness. Also, the course will discuss the various tests conducted on asphalt courses such as density, degree of compaction, stability, flow, and thickness. This course will discuss the Marshall method, Marshall method used to select the suitable bitumen content for a specific gradation of aggregates by testing specimens to assess their properties and suitability.
Secondely, in this course you will learn almost everything about concrete. Concrete is the most used material in construction worldwide. We can find material 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. 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.
