Raw Materials

Aggregates Part 1

We may think about aggregates as just a pile of sand and stone. Actually, aggregates are a critical component of any concrete product. In this course we discuss how aggregates affect concrete performance including aggregate size, shape and texture.

Aggregates Part 2

We said before that size and shape matter for aggregate performance. During this course we dig deeper into concepts like particle packing and fineness modulus. Learn how to read a grading curve, and how different curves are applied to different units.

Cement

In this video we explore the basics of how cement is made and different types of cement available to us. High and low temperatures can have an important impact on cement hydration. Learn about the hydration process and how it can impact you.

Pozzolans - Fly Ash & Slag Cement

Join us as we travel deeper into cementitious materials to include pozzolans like fly ash and slag cement. The pozzolanic reaction helps us to make high quality, economical products from recycled raw materials.

Admixtures

Have you ever wondered what exactly admixtures do? Find out how admixtures contribute to concrete quality, lower costs and accomplish some performance attributes that we can’t get any other way – like making a CMU water repellent right out of the box.

Production

Quality Assurance/Quality Control Part 1

Do you think that only machine operators and QC folks need to know about QA/QC? Not so! Everyone at the plant, including sales and customer service need to understand how what we do affects the performance of our units. We show you some quick, relatively inexpensive ways to incorporate raw material QA/QC checks into your daily routine.

Quality Assurance/Quality Control Part 2

Can you predict the future of your concrete? Incorporating inline moisture and quality checks can alert you to problems while there is still a chance to do something about them. These include “old-timer” manual checks, moisture balance and bake-off methods.

Controlled Curing

Concrete has its best shot to reach maximum potential when properly cured. This means that proper curing can really help, and poor curing can really hurt in a few important ways. Find out more about different curing methods, and how time, temperature and humidity help concrete to perform at its best.

Efflorescence

Did you know that any product that contains cement has the potential to effloresce? In this video we talk about what efflorescence is, how it happens, and how to reduce the potential for it to occur. Many factors can combine to produce efflorescence, and sometimes it’s all hands on deck to stop it. Find out how Raw materials, mix design, curing, handling and even the weather can play a role.
