Why is concrete such a widely used material? What are the different types of concrete and when should they be used? Answer these questions and more in this fascinating and in-depth course. Generally preferred for its strength, durability and fire resistance, concrete is a familiar material to many engineers, contractors and technicians. However, few have the technical expertise of concreting under unique conditions and environments. In this course, you will learn the skills needed to handle concrete under ordinary circumstances as well as the special types of concrete used in hot and cold weather conditions and underwater or marine environments.

First, you will be introduced to the composition of normal concrete, the properties of materials that are mixed to make it as well as the techniques used to determine the proportion of each ingredient that will be used. You will then go on to study the properties of the concrete in both a fresh and hardened state. Next, you will explore special concrete, beginning with the additives, technically known as ‘admixtures’, which are added to ordinary concrete to improve its properties. This will be followed by a discussion about concreting in cold weather and its effect on concrete curing and strength development, as well as the methods used to overcome these challenges. Concreting during hot weather and measures that are taken to minimise its adverse effect on concrete will be addressed. This will pave the way for the discussion on the specially-formulated anti-washout underwater concrete and how it is prepared. As you will find out, specially-mixed concrete is used for the marine or aquatic environment. One of the most interesting procedures is placing the concrete and compacting it underwater. You will learn how this is done while ensuring that ocean waves and tides do not wash away the concrete. Lastly, you will study roller-compacted concrete and its uses. 

Construction in unusual conditions and circumstances is increasing as more offshore structures are being built, from jetties to shipping docks to bridges connecting different places. Construction in predominantly hot and cold climatic regions is also occurring as buildings, roads, and bridges are being developed. Professionals in the construction industry are therefore required to be versatile, well-versed and equipped with unique skills, particularly in concrete work, for these circumstances. This course will benefit anyone in the construction industry, from engineers to contractors and artisans, particularly those seeking to expand and diversify their skillset or refresh their knowledge. Students and anyone aspiring to join the industry will also find this course fulfilling and inspiring as they embark on the exciting journey to mastery in the building and construction industry.
