Description
When most people think of mass concrete, the first things that come to mind are large dam projects, such as the Hoover Dam that borders both Arizona and Nevada, and other Corps of Engineer dam projects built in the 1930s through the 1960s. In fact, most of the information contained in ACI 207.1R-05 (2012), “Guide to Mass Concrete,” was derived for, and from, these types of projects. However, projects such as wastewater treatment vaults with thickened floor slabs, large mat foundations, pile caps for drilled piers, and large inertia mass machine foundations may require different approaches for mass concrete placements that extend beyond ACI 207.1. This webinar will discuss methods of designing, placing, and protecting mass concrete and realistic thermal-control plans. Examples of actual jobs and field studies will be included in this session.

Learning Objectives
1. Explain the practical concept for Massive Structural Concrete:“Can’t keep it cool? Keep it warm,” an alternative approach to designing, placing, and protecting mass concrete structures.
2. Identify measures taken to ensure internal maximum temperature is no more than 35°F (∆T) greater than the external temperature.
3. Describe how to place a hard trowel finish on the surface of a low-heat, slow-setting mass concrete mixture in a cold environment.
4. Discuss how long it takes for heat to dissipate from a mass structure.
