Let's just say it up from, a good story is a good story and good information is good information. While some of the following were also popular in months prior, data found a few new pieces that stood out too. 

Here are the most popular stories from December 2020 be they news, articles, or video.

Cold Weather

Hey, did you know it's winter? Colder temperature slows work down, snow needs to be dealt with, etc., etc. Yet work needs to continue. As such, working concrete in the cold weather ended up being a popular interest. One of such is how to improve cold weather concrete pouring with calcium chloride. There are limitations to where and when you can use it, but this piece looks to answer a few questions.

Contraction Joints

Kim Basham writes out 10 great rules for designing contraction joints dealing with layout, maximum joint spacing, joint depths, and sawcut timing. No mention on if these change for cold weather though.

It's as close to viral as one can be. The time-lapse of United Kingdom's longest concrete pour for the Kinkley Point C Reactor continues to be popular. Here's your chance to check it out if you haven't seen it yet.


The Concrete Contractor cover story of December 2020 discussed the movements being done in reducing the carbon footprint of concrete and cement. An excerpt:

For how long it lasts, many have considered the carbon footprint of concrete to be relatively low. Cement, however, produced 2.2 billion tons of carbon dioxide (CO2) in 2016, or 4% of total emissions, according to the Emissions Database for Global Atmospheric Research, making it one of the world’s greatest contributors to climate change. Improving the carbon footprint of cement and concrete is also important as cement production is expected to increase by 25% by 2030 while cities around the world become more urbanized.

Gigi Wood writes a great story on the work done by the key players in the industry as of late 2020.

One Wisconsin contractor wrote Jim Baty II about pouring in cold weather.
