Scientists have uncovered the structure of cement

Researchers were able to determine the structure of frozen cement. Article researchers appeared in the journal Proceedings of the National Academy of Sciences, and its summary is provided on the website of the Massachusetts Institute of Technology, whose staff participated in rabote.V the study team used a neutron interferometry to determine the structure of the material. To use this method, samples are irradiated by an intense flux of neutrons. Study pictures of dispersion allows scientists to determine the structure of materiala.Ranee researchers assumed that the concrete structure resembles the structure of a rare mineral tobermorita. In Tobermory, Mull has several layers: one composed of silicon atoms forming cells in the form of a tetrahedron, and the second - from calcium oxide. In the new work of the scientists were able to determine that the concrete structure of the layers a little otlichaetsya.V particular, they found that the structure of concrete is not completely crystalline. In particular, in some places silicon tetrahedra "emerge" from your layer in the oxide layer kaltsiya.Po scientists said the new data will create a more sophisticated model of concrete. Experts hope that they will modify the existing production of this material, at least in order to reduce emissions of carbon dioxide in the atmosphere. The fact that cement plants are responsible for about 5 percent of all emissions.
