Perm National Research Polytechnic University (PNRPU) has presented a new composition of dry building mix for self-leveling floors. It is based on fluoranhydrite, a by-product of hydrofluoric acid production. This innovation could change the approach to construction and waste disposal.
Each year, Russia generates up to 350,000 tons of fluoranhydrite, which is not recycled and is stored in landfills. Scientists have proposed using this material as a component for creating a binding agent.
Research has shown that a mixture with the addition of 15% fluoranhydrite and activators (Portland cement and fly ash) increases strength by 46% and has high water resistance.
We have selected additives such as superplasticizers and defoamers to achieve the desired flowability and plasticity of the solution. The resulting material has high strength and is comparable to commercial counterparts.
According to scientists, the new building mixture will not only help reduce the cost of work, but also solve the problem of waste disposal, which makes it an important step towards more sustainable construction.
Earlier www1.ru reported that in Russia developed a new mixture for creating building tiles from industrial waste.
