There’s been a lot of talk about the benefits of high flow concrete, but how do you know when to use it and when conventional concrete is sufficient? First, let’s define the different types of concrete.

  • Conventional concrete: Normal slump concrete has been used successfully for decades, but can be difficult and labor intensive to place.
  • Self-consolidating concrete: This is a specifically designed mix, typically containing higher cementitious contents and smaller size coarse aggregates. Self-consolidating concrete mixes are typically more expensive, but require less labor than conventional concrete to place. Self-consolidating concrete’s moisture tolerance can be sensitive, so you need to have sufficient quality assurance staff in the field to ensure the right consistency. 
  • Control flow concrete: This category of concrete bridges the gap between conventional concrete and self-consolidating concrete. Control flow concrete uses conventional mix designs, larger coarse aggregates and GCP Applied Technologies’ CONCERA® water reducing admixture. Therefore, material costs are lower than self-consolidating concrete. 

Let’s look at the characteristics of each type of concrete.

Many factors need to be considered with choosing a specific concrete category.  First, consider where the concrete will be used. For example, control flow concrete is ideal for most slab on grade and formed concrete applications, while self-consolidating concrete is advantageous for use in highly reinforced and very difficult to cast applications.   

Additionally, when considering the price of each type of concrete, you’ll want to take into account the cost of the materials, as well as the cost of labor in the region. Since higher flowing concrete, like control flow concrete and self-consolidating concrete, significantly reduce the amount of labor involved with placing concrete, their benefits are even greater when they’re used in cities with high labor rates.

Lahey Hospital and Medical Center, one of metro Boston’s premier medical facilities, needed to relocate its general internal medicine (GIM) department through a fit out of a nearby 37,000-square-foot site. In addition, the hospital required a 4,000-square-foot diagnostic fit out on the first floor. The new department needed to be up and running by a fixed date and had to be moved from the midst of a functioning hospital into an occupied office building while minimizing disturbance to both locations.

Being relatively new to the tech explosion we shouldn’t be dazzled by the latest bright and shiny toys. We need to focus on some of the basic building blocks or concepts that ensure technology success before we take advantage of the many SaaS-based, best-of-breed applications in the market. Here are three areas to think about:

Even though we are aware of the many factors that caused the skilled labor crisis, and there’s still no universal remedy for the labor shortage, there are some recommended steps that organizations can take to help attract and retain talent in the construction industry. 

Blog 115 Construction Labor ShortageBy Brian Binke

A skilled labor crisis has burdened organizations of all sizes in the construction industry for much of the past decade. Construction recruiting is as competitive as it has ever been as experts point to a variety of different causes ranging from retirement and increased building demand to the recession and a lack of vocational programs. Even though many CEOs might have their own reasons why there is labor shortage, it’s important to understand how each of these reasons have played a part in creating it in order to find legitimate solutions.
