Employees of the Tomsk State University of Architecture and Building (TSUAB) have developed innovative cement composites that significantly increase the strength of building materials. The new compositions become 30-36% stronger in 28 days.
The technologies used by scientists can be applied in difficult conditions, for example, when arranging oil and gas wells. The main advantage of the new compositions is that they can be produced without additional grinding, plasticizers and steaming, which greatly simplifies the process.
In addition to cement composites, specialists have created a lightweight thermal insulation material based on paper and modified polyurethane. It has high strength and lower weight, making it ideal for modern construction. A paper-based building material with polymeric binders has also been developed, which can withstand pressures from 21 to 34 MPa, which is comparable to the load from a cargo weighing 2-3 tons per square meter.
In addition, researchers focused on composites for the oil and gas sector. The optimal ratio of polyurethane additive increases compressive and flexural strength by 14% and 10%, respectively. In addition, the use of new materials reduces moisture absorption by 1.8 times, which significantly increases their efficiency.
