During this presentation we will examine the origins of concrete as a building material, and consider the milestones of development that were made to achieve the advanced concrete technology of today. We will learn about careful material selection and the importance of such concepts as water cement ratio by exploring the historic perspective of those who contributed to the progress of the concrete industry. We will examine some examples that emphasize just how durable concrete is, and take a closer look at what effects the durability of such structures. Shea Concrete Products is excited to announce our 8th “Virtual” Technical Engineering Seminar that is available through our Podcast (The Precast Podcast) and will allow for an online library of technical seminars that professionals can access to gain industry knowledge and stay current with professional development credit hour requirements. This "virtual" seminar opportunity allows for participants to obtain two (2) individual professional development credit hours as follows:

• 1.0-Professional Development Hour (PDH)
• 1.0-"NHDES Subsurface Systems Bureau" Credit Hour (NHDES Subsurface Designers & Installers)
