Description

Cement is one of the most widely used and known construction materials worldwide. When mixed with other ingredients, it forms concrete, which is rock-solid in its hardened state. Now, would you imagine concrete without cement? Is it even possible? Would it work? This course will answer these questions as it introduces you to other binders that can be used in place of Portland cement and still produce strong concrete; a little-known fact even to many experienced construction practitioners. Firstly, this course will take you through the basics of mixing concrete, the procedures and methods applied and the types of mixers used in the process. This will be followed by a discussion on ready-mixed concrete, after which shotcrete will be introduced. The definition of shotcrete, its applications, and its characteristics will be examined in detail. A special type of concrete known as high strength concrete will then be uncovered, together with the materials used to make it as well as its purpose and advantages over normal strength concrete. Its characteristics will also be explained along with its design process. Then, you will discover polymers, a type of materials that can be used in place of cement or alongside cement to improve concrete properties, chemical reaction processes, and polymer concrete applications.

Next, you will study the importance of improving the quality of cover concrete and the role of formwork towards this objective. You will learn the different types of formwork and their specific applications. This will be followed by concrete compaction and its purpose. You will be taken through the compaction process, the various types of compaction, and the effects of improper compaction. Furthermore, you will discover that too much compaction is bad for concrete and why this should be avoided. This will pave the way for a discussion on the use of Precast Concrete (PCC) and the steps involved in its preparation and construction. The methods used in curing PCC will be revealed, and the application and advantages of PCC over ordinary concrete will be outlined. Did you know that you could reuse waste materials salvaged from construction and demolitions to build new structures? You will learn all about how this is done, and the methods used in separating valuable materials from those that cannot be recycled. Needless to say, the quality of the recycled materials may not match those of fresh and new materials. So you will learn how this limitation is handled to ensure that the resulting structure is robust and structurally sound.

The importance of special concretes cannot be overemphasized, as they are essential for use under particular circumstances and environments. Professionals in the construction industry should therefore be well versed with their use, preparation, and characteristics. This ensures that building practitioners remain versatile, adaptive, and capable of handling projects under any circumstance. Further, knowledge and skills in recycling construction waste are useful, especially in today’s world, where we need to take care of the environment for sustainability purposes. If you are a professional in the building and construction industry and would like to enrich your skills or to refresh your knowledge, or if you are aspiring to join the field as a contractor, engineer, technician, artisan or in any other capacity, this course is for you. So, do not hesitate, start the course now!
