Cement
Course Description:
The terms cement and concrete are often used interchangeably – but they are not the same thing. Cement is one ingredient in concrete like flour is one ingredient in a cake. And just as flour binds a cake together, cement binds all the aggregates together forming concrete.
Cement is a critical part of concrete that has a major impact on the concrete product’s strength, durability, and color. In this course, we explain how cement chemically reacts with water during the cement hydration process and hardens to form cement paste which is the glue that holds the aggregates together forming concrete. We discuss the effect that low and high temperatures have on how fast the cement reacts and the concrete gains strength. We explore the balancing act between using enough cement for strength development but not using too much which can cause other problems and contribute to increased efflorescence. We also discuss the different kinds of cement available to us including the new Portland-Limestone Cement (PLC).
After taking this course, learners will understand:
• What cement is and how it is made
• How the chemical process of cement hydration works
• The impact of temperature on the cement hydration process
• The negative consequences of using too much cement
• The properties and uses of some of most common cement types
• How cement impacts color
• The environmental benefits of PLC Cement - Portland Limestone Cement
