As global awareness of environmental issues grows, the construction industry has increasingly looked towards sustainable practices, including the use of sustainable concrete. Concrete is a widely used construction material, but it also contributes significantly to greenhouse gas emissions. Therefore, it's essential to consider how to make concrete construction more environmentally friendly. By adopting sustainable techniques, we can reduce concrete's carbon footprint and create greener, more eco-conscious structures.
The demand for sustainable materials and techniques is on the rise, and the concrete industry is no exception. With the right information and practices, it is possible to create sustainable concrete. In this article, we will explore some tips on how to make concreting and concrete more sustainable.

We gathered our best tips on how to make concrete and concrete construction more sustainable. Keep reading to learn more about what you can do to have your construction company minimise its carbon footprint.
Reduce the environmental impact of concrete by incorporating alternative cementitious materials, such as fly ash, slag cement, or silica fume. These materials can partially replace Portland cement, which has a high carbon footprint. Read more about more sustainable concrete mixtures in our article.
With the increasing demand for sustainable solutions, the question "is precast concrete sustainable?" is frequently asked. Precast concrete is a sustainable alternative to traditional cast-in-place construction.
It involves producing concrete elements in a controlled environment before transporting and assembling them at the construction site. This method offers several benefits:
Reducing energy consumption during concrete production can significantly lower the concrete carbon footprint. Adopting energy-efficient practices includes:
Recycling concrete reduces the need for new raw materials, decreases waste, and lowers the overall environmental impact. Consider the following tips for recycling and reusing concrete:
Design structures with sustainability in mind, considering factors such as the building's lifespan, energy efficiency, and adaptability for future use.

In conclusion, sustainable concrete can be achieved through a combination of alternative materials, precast methods, energy-efficient production, recycling, and thoughtful design. By implementing these techniques, the concrete construction industry can significantly reduce its environmental impact and contribute to a greener future.
Concrete production is responsible for approximately 8% of global CO2 emissions, primarily due to the energy-intensive process of producing Portland cement. This process involves heating limestone and clay at high temperatures, which releases large amounts of CO2.
Yes, when properly processed and used in appropriate applications, recycled concrete can maintain similar performance and durability as new concrete. Engineers carefully design concrete mixes using recycled materials. This is to ensure that the structural and durability requirements are met.
While alternative cementitious materials can reduce the carbon footprint of concrete, they can also affect its properties. For instance, setting time, strength development, and durability. Proper mix design and testing are crucial to ensuring that the desired performance is achieved.
Discover how real-time concrete monitoring technology, like Converge's ConcreteDNA, is revolutionizing tilt-up construction by improving safety, efficiency, and sustainability through accurate tracking of concrete curing and strength.
Mass concrete pours present challenges due to the heat generated during curing, which can cause thermal cracking. Converge's ConcreteDNA uses smart sensors to monitor temperature and strength in real-time, optimizing curing and preventing cracks.
The success of post-tensioning relies heavily on precision and control. Learn how real-time monitoring and innovations in sensor technology can mitigate risk and boost the efficiency of post-tension construction.
