Newly Developed Concrete Materials Are More Environmentally Friendly

Concrete development lab

At Demolition Technologies, one of our goals for each demolition project we take on is to recycle and salvage a high percentage of the materials involved. Because of this dedication to environmentalism, we're pleased to hear about the research being conducted to improve the efficiency of concrete production with greener materials. Here's an overview of two of the works in progress that could result in more environmentally friendly concrete being used in a variety of projects.Concrete materials are used in all sorts of construction applications, and one estimate puts the manufacture of Portland cement as accounting for 5 percent of the world's CO2 emissions. Even with efficient demolition processes, that leaves a lot of room for improvement.One British company claims that if the Empire State Building had been built with their product, it would have produced 13,319 fewer metric tons of CO2. This is possible because they've developed a cement-free concrete material. Some skeptics believe this method is similar to "baking a cake without flour", but preliminary testing has shown it performs equal to traditional concrete in many applications.This cement-free concrete has additional benefits, as well. It's held together by ground-granulated blast furnace slag, which is a waste product from the steel industry. So, production not only cuts down on CO2 emissions, it also reuses waste.Ultra-high-performance concrete, UHPC, is another example of improved concrete materials. Because it's made up of tiny, tightly packed particles, it becomes extremely strong when compressed. That means UHPC is more durable than traditional concrete, and requires less water. It also means that less UHPC is required in a project to achieve the required strength.One company, Taktl, is taking it one step further and making even its delivery method more efficient and green. Rather than producing their product from one central location, their plan is to open several regional plants that can use locally sourced materials to produce their product. This delivery method puts less stress on one particular area, or natural resource, and allows for fewer emissions in product delivery due to shorter routes.One element of these newly developed concrete materials is how reusable they are after demolition. If these materials can be crushed or salvaged and used in other projects to prolong their lifespan, their more efficient production methods will be a step in the right direction.To learn more about our dedication to environmental stewardship in demolition, and our overall demolition capabilities and experience, contact us at 918-379-0966.
