Sustainability and green movements have been quickly taking over industries, and construction is no different. Every year, 20 billion tons (10 billion cubic yards) of concrete are produced globally. This makes it the second most consumed product on earth, after water. Cement is not only the most expensive ingredient in a concrete mix, but its production is also responsible for 8% of global CO2 emissions.
Ready-mix concrete, concrete that is batched for delivery from a central plant instead of being mixed on the job site, is pre-calibrated and tailor-made to match the project’s target specs, allowing for contractors to request specifications to better control and optimize the performance of their mixes. In a construction project, ready-mix concrete producers design concrete mixes to meet specific performance criteria to reach strength targets quickly. However, concrete producers have limited data and visibility into these factors, thus lacking accurate testing and monitoring capabilities. This leads to overdesigning the concrete mixture by adding more cement than necessary to prevent potential performance issues.
While green technology is often seen as a challenge on the jobsite, the silver lining lies in ready-mix concrete producers onboarding green values and technology. Below are the top 11 ready-mix concrete producers in North America who are leading the sustainability mission.
