At the National University of Science and Technology MISIS, a costly building material has been developed from waste generated during water purification. This was reported by the university's press service.
The new method allows for the processing of lime waste into synthetic calcium sulfate (anhydrite) with a purity of up to 99.8%. The material can be used to produce cement with a strength of over 28 MPa.
Imagine that from the remnants of lime that remain after water purification, we make a material that can be used for the construction of houses, roads, or other objects. And all this at a low temperature of up to 40 °C and lower costs than traditional methods, which use temperatures up to 900 °C.
Scientists plan to optimize the technological process to increase productivity and reduce costs, as well as adapt the methodology to work with various types of waste. Research will also be conducted on the environmental aspects of anhydrite production, which will make the waste recycling process accessible and in demand on a global level.
The new synthetic anhydrite can be used in the construction of bridges, canals, dams, and airfields, where its improved characteristics play an important role.
Earlier, www1.ru reported that in Mordovia created a super-strong polymer from multilayer packaging waste.
