Green concrete: Learn how this innovation using coal ash increases strength and reduces carbon emissions!
Researchers in Australia have developed an important innovation for the construction industry: the green concrete. This new material uses coal ash as a substitute for cement, which not only improves the strength of concrete but also significantly contributes to reducing carbon emissions. The use of green concrete increases the durability of buildings and minimizes environmental impact, making it a more sustainable solution for the future of civil construction.
The innovation of green concrete
A innovation green concrete comes from replacing cement with coal ash.
Cement, responsible for around 8% of global carbon emissions, is the environmental villain of traditional construction.

- BRICS! After Trump's warning, two countries warn the US president that they have no plans to replace the dollar
- Google shares soar after quantum chip announcement can perform 'impossible' tasks in five minutes that take current supercomputers 10 septillion years to complete
- NASA flies over almost 500 km² in search of rare earths and exposes America's gigantic mineral wealth
Green concrete, by reducing the amount of cement, offers a more ecological alternative.
Coal ash production in the world is abundant, with more than 1,2 billion tons generated annually, ensuring a constant source for the manufacture of the material.
By using more coal ash in its composition, green concrete becomes not only sustainable, but also stronger and more durable.
Increased strength and durability
Os tests with green concrete they showed that it is more resistant than conventional concrete.
It showed increased compressive strength, greater flexural strength and greater elastic strength, increasing its durability.
When exposed to adverse conditions, such as acids and sulfates, green concrete has proven superior, with a resistance that surpasses that of traditional concrete over time.
These results reinforce the potential of concrete to be used in a variety of constructions, ensuring that structures are stronger and more durable.
Innovation in the use of nano additives also plays a fundamental role.
These additives alter the chemistry of green concrete, allowing more coal ash to be used without compromising the strength and durability of the material.
This chemical modification not only improves the strength of the concrete, but also makes the manufacturing process more sustainable by reducing the use of cement and, consequently, carbon emissions.
Environmental impact and reuse of ash
Reusing coal ash in green concrete offers an environmentally responsible solution to a problematic waste product.
Ash ponds, often found at dams around the world, pose a risk to the environment.
By using these ashes for the manufacture of the material, researchers propose a way to reduce the environmental impacts associated with the disposal of this material, while contributing to the reduction of carbon emissions.
Furthermore, replacing cement with coal ash in green concrete has the potential to transform the construction industry, making it more sustainable and resilient.
Dr. Chamila Gunasekara, the project leader, highlights that concrete can be a great advantage for the industry, as it offers a more ecological and resistant alternative to traditional cement, in addition to contributing to the reuse of resources that would otherwise be discarded.
Green concrete as a viable alternative in the future
Green concrete represents a innovation significant for the construction industry.
It combines strength, durability and sustainability, while reducing carbon emissions.
This innovative approach opens up new possibilities for building more resistant structures, while contributing to environmental preservation.
Using coal ash in green concrete offers a viable and scalable solution for building a more sustainable, lower-carbon future.
We have buildings that predate the use of cement, in a more solid state than the current ones!
Hello, good afternoon! I have used this content, how can I get more information? 65.996306161
What's new? Coal ash has been used in cement for over 50 years. CPIV and CPIIZ cements.
Exactly. Stuff to fill sausage
Cimento CP IV has been doing this for years. At least 25 years ago when I started working with concrete. This report is ****.
Does it contribute to carbon reduction?
You've got to be kidding me!?!?!
And to produce coal ash you don't need to deforest or burn anything?!?!
Please…..
We have a patented cement that does not contain clinker. This reduces CO70 emissions by around 2%. Follow my profile and I'll show you there. @prof.eduardo.cabral
