Concrete is the most widely used building material in the world. Today's construction professional needs to understand how this material works, how it has evolved and how it is made. The course includes discussions on the chemistry behind making concrete, and the evolution of the science behind making concrete. These are things that today's construction professional needs to understand in order to effectively manage today's projects. You will learn the meaning and origins of the terms and processes used in the industry by today's concrete producers and engineers so that you become a more effective and more professional construction pro.
Gain a better understanding of the chemistry behind the Worlds most widely used building material and learn how its production has evolved to produce a more advanced and eco-friendly finished product.
After completing this course you will be able to...
Learn from a professional
My courses have been created as a place where everyone, whether you are an experienced professional, a young project engineer, new to a trade or a seasoned journeyman, can come to learn more about the industry that we have chosen as our profession. That's what this platform is about. These courses are meant to be a way for you to increase your knowledge of the construction industry in a variety of cutting edge topics from concrete reinforcing and prestressing, to micro trenching, to safety management systems. These are not meant to be how-to courses. These are meant to be courses that educate you on a construction topic and give you a real understanding of how something works or why its being used. This is also meant to be an unbiased platform that discusses both the advantages and the limitations of the topic being taught.
This course is a great way for you to increase your knowledge about the material science behind the production of concrete.

|Section 1: Introduction|
This section introduces you to the most widely used building material on the planet! In fact, concrete is the most widely used man-made material on the Earth.
|Quiz 1||6 questions|
This opening section will quiz you on how much you already know (or can guess) and set the stage for the materials to be covered in the next 30 minutes.
Cement is just one of the ingredients in concrete. Cement, also called Portland Cement, is often referred to by engineers as Hydraulic Cement. This term refers to the fact that concrete hardens due to a chemical process, not by simply drying out. Since this chemical process takes place in the presence of water, it can, in fact, harden under water.
|Section 2: Welcome|
This course is one of many (current and planned) meant to educate today's construction professional about a wide variety of topics in the construction industry. The goal of this course is to educate you about the science behind the making of concrete and to inform you of some of the modern advances and practices used in the industry today.
In its simplest form, concrete is mix of paste and aggregates. One of the key things that makes concrete such a widely used material is that it is plastic and workable when it is freshly mixed, and it hardens to a strong durable material.
Concrete comes in several different forms:
You can download the complete Concrete Technology Guide, published by the American Concrete Institute, using the link in the RESOURCES section. This free resource is a complete guide to the terms and definitions used in the industry.
|Section 3: What's In Concrete?|
Here we learn about the ingredients in modern day concrete, including industrial by-products and chemical ad-mixtures. We also discuss the chemical process that causes concrete to get hard, known as "hydration".
Learn why we use the terms Portland Cement and Hydraulic Cement to refer to virtually all of the cement we use today.
|Section 4: Beyond the Basic Ingredients|
This section discusses one of the most widely used industrial by-products in the concrete industry - Fly Ash.
Fly ash has been used in concrete for many years, but it was not well understood in the early years which led to misuse. When used properly, this industrial by-product can greatly enhance the properties of concrete, making it:
Much more than just a filler, this material makes concrete better and makes it more "green" or eco-friendly.
The RESOURCES section of this lection contains several handouts that contain additional details about fly ash in concrete.
|Lecture 8||2 pages|
A pozzolan is also known as a supplementary cementitious material. This is a material that does not act like cement by itself, but it takes on the same behaviors and properties as cement when it is used in concrete along with cement.
This section is an introduction to the different types of chemical add-mixtures used in concrete and their effects on the product in both its workable state and its final hardened state. This includes the following classes of admixtures:
Water is needed to make the concrete mix plastic and flowable, but too much water decreases strength. A proper water to cement ratio is needed to ensure required strength of the finished (hardened) material.
|Section 5: Sustainability|
The concrete and cement industries are working to become more sustainable. These efforts focus on four main areas:
|Section 6: Check Your Knowledge and Conclusions|
|Quiz 2||10 questions|
Answer these questions to see how you measure up against the learning objectives given at the beginning of this course.
Thanks for completing this course! If you have reviewed all of the instructional materials and downloadable content, you should now have a better understanding of concrete and its components, including supplementary cementitious materials and chemical admixtures.

I work in the School of Sustainable Engineering and the Built Environment at Arizona State University. I have been a faculty associate in the construction management program and have taught many undergraduate and graduate courses in that program, including courses in concrete, scheduling, productivity and safety. I am currently the Director of the school's OSHA Training Institute Education Center where I develop, produce and teach many courses in occupational safety and health for construction and general industry.
Prior to joining ASU, I spent many years in the construction industry including roles managing a public works contractor in California, a large concrete contractor in Arizona and I managed a division of one of the largest post-tensioning companies in North America. In between my industry roles and my latest role teaching, I spent some time working for industry associations and acting as a consultant for a large construction union. I learned a lot in these different roles and as I have progressed I have come to realize that our industry has a real need to do a better job disseminating knowledge.
My teaching experience includes the following academic courses taught at Arizona State University:
--CON 100 - Introduction to Construction
--CON 271 - Construction Safety
--CIM 205 - Concrete Construction Methods
--CIM 306 - Concrete Plant Management
--CIM 494 - Reinforcing and Post-Tensioning
--CON 494 - Temporary Structures and Reinforcing Methods
--CON 495 - Planning and Scheduling
--CON 540 - Construction Productivity
I also have a number of published articles and write a regular construction safety collumn for Concrete Construction Magazine.
