Concrete may seem basic at first glance, but a lot of thought is put into creating the right kind of batch for the project you are working on. Aggregates, mixing techniques, the weather – they all affect the quality in simple. but profound ways. Delve into the heart of concrete and see the science behind these simple, yet important building materials.

This webinar was held last October 21, 2020. For those of you who missed out, don’t worry, we have timestamps below and more webinars coming your way. Stay tuned!
