New ecological concrete created in Malaysia

Researchers from the MARA Technological University have developed this new type of ecological concrete in which ashes from coal plants, recycled concrete and fibers from aluminum cans are mixed in its composition. The result is more than surprising. A sustainable, profitable concrete with a 30% higher resistance.

This combination of materials has resulted in an environmentally sustainable concrete with a resistance that reaches 30% higher than that of concrete, in addition to contributing to the GBI (Green Building Index) score launched by the Malaysian Government to promote construction of buildings that use green technology and reduce air pollution.

Another interesting aspect of this concrete is that being developed with recycled materials reduces costs, uses sustainable raw materials recycling waste and its carbon footprint per unit is much lower than that of conventional concrete. In addition, by reusing industrial products that would end up in a landfill, it has the commercialization potential of being an environmentally friendly product.

Let's see the characteristics of these materials that are introduced into concrete:

Fly ash is a waste product from coal power plants that is stored in ponds until it is sent to landfills. Through research, it was discovered that fly ash has the potential to replace cement, a material with great environmental impacts due to pollution.

Waste generated from demolished concrete structures, crushed concrete can be reused as substitutes for gravel and sand. With the particularity of having greater resistance.

Aluminum cans processed into staple fibers are used as reinforcement in concrete that acquires excellent qualities.

In conclusion, the new concrete has the following benefits:

- Designed to withstand the entire service life of buildings or structures.

- It has the smallest cement / carbon footprint per unit of concrete produced.

- It has commercialization potential, providing builders and contractors with an alternative that is respectful of the environment, in accordance with the National Green Technology Policy.
