First Graphene today released a technical update on the application of its proprietary PureGRAPH® graphene as an additive in cement grouts and concrete.
The study shows that graphene admixtures increase strength, reduce materials usage (reducing carbon footprint) and potentially increase longevity of products. This analysis is noteworthy since cement is estimated to amount to 6% of all CO2 emissions from human activity.
Cement is the most manufactured and traded product globally after water, which is causing enormous climate change challenges to reduce its carbon footprint. In 2015, the total mass of cement produced was 4.6 billion tonnes. This is equivalent to about 626 kg per capita, a value higher than the amount of human food consumption.
With population growth, increased urbanisation and improved living standards of the global population, the demand for concrete products continues to grow at an accelerating rate.
First Graphene Managing Director, Craig McGuckin says:
“The initial work demonstrates a low dosage of PureGRAPH® generates an increase in compressive and tensile strengths, when compared to the base product,”. Mr. McGuckin further stated “While there is a considerable amount of further work to be done, this is very encouraging for enhancing the performance of concrete both new and recycled, but equally the sustainability benefits for the environment.”
