ECS Participates In Largest Continuous Concrete Placement in Wisconsin History

Northwestern Mutual Tower and Commons, Milwaukee, WI

9200 CY Mat Slab Pour for 32-story Office Building, March, 2015

As you might imagine a lot of planning goes into the construction of a 32-story office building.  The first part of any building is the construction of the concrete foundation.  For this project, the building will be supported on a 10-foot thick concrete mat slab constructed in one continuous pour.  The placement of 9200 cubic yards of concrete is a challenge for even the largest general contractors.

Hot Weather Concrete Construction Practices

Last time, we talked about the effects of hot weather on concrete curing. In this blog post, we’ll discuss several basic precautions that can reduce the damaging effects of hot weather on concrete:

Hot Weather Concrete

In the concrete business, hot weather creates situations that require special procedures for proper mixing, placing, finishing, and curing. Hot weather conditions include high ambient air temperatures, high concrete temperatures, low relative humidity, and/or high winds. Any of these conditions can impair the quality of freshly-mixed or placed concrete, and this blog discusses the effects of hot weather, as well as construction practices that may help lessen their impacts.

Cold Weather Concrete

With the approach of winter, it’s time to remember cold weather concreting practices. According to the American Concrete Institute® (ACI)’s publication, “Guide to Cold Weather Concreting,” (ACI 306R) cold weather is defined as any time the air temperature falls or is expected to fall below 40°F during the protection period (the time required to prevent concrete from being affected by exposure to cold weather).
