Lately, more and more companies in the concrete industry are starting to come out with their own low-carbon concrete mixes. For instance, several companies that range from Nova Scotia, Canada, all the way to North Carolina in the United States of America (USA) have started to experiment with how they develop their concrete. And in one case, the American division of a large European company managed to create a mix that lowers the carbon in concrete by 30%.
With all this interest in greener concrete mixes, you may wonder if this is a trend you yourself should follow. But we believe it will be more than a trend. Soon, it will likely be a necessity. To give you an idea of why that is (and how we can help), let’s explore the main reason for its increasing popularity.
There are a number of reasons. But the biggest is simply that regular concrete is the cause for at least 8% of the world’s carbon emissions. That’s a significant chunk of pollution that comes with a number of expenses. The most obvious is the cost of environmental damage. This not only lowers the quality of the air and more in nearby areas, but it also makes creating concrete much more expensive. After all, many countries employ some sort of carbon tax, adding to construction costs. And it takes a lot of energy to produce the cement in the concrete, adding even more to the budget.
In response, the industry has looked for alternatives to reduce the environmental and financial impact of concrete construction. They soon found they could minimize it significantly through the use of by-products. These would replace some of the cement used in concrete, lowering how much energy companies would use up to produce concrete slabs. So they’d substitute some of their concrete’s cement with materials that would otherwise go to landfills. These include materials such as fly ash and slag.
Unfortunately, these materials are becoming harder to get. This is mainly due to green efforts from a number of countries. As they look for less environmentally harmful solutions, they stop creating by-products like fly ash.
So construction companies are now looking at other ways they can reduce carbon emissions in concrete. That’s where low-carbon concrete comes in.
While it can be more expensive, it makes pollution less of an issue. Some companies even consider it a valuable way to create their own specialized low-carbon mix. After all, this gives them a way to differentiate themselves in the market and potentially win more projects that need more environmentally friendly construction.
