a cement mixture, which contains the dopa - melanin, his predecessors, analogues or derivatives as additives with significantly improved physicochemical and bacteriological properties

摘要

the present invention provides cement compositions, which contain dopa - melanin, his predecessors and / or its analogs as additive at the content of 30% of the cement.this additive is replacing water in capillary networks, the water / cement ratio of the cement mixture is from 0.2 to 0.4.not necessarily, it may contain various quantitative ratio of sand and gravel.u0437u0430u044fu0432u043bu044fu0435u043cu0430u044f cement mixture forms strong chemical bonds, and provides increased resistance to flushing, at least 28%, and the higher resistance of lumpy in here concrete, at least 50%.the cracking in the early stages of a very low or nearly zero.the application also relates to the use of dopa - melanin, and / or its predecessors, and / or its analogues as additive in cement mixturewhich is part of the capillary water in the cement mixture.as well as to the use of dopa - melanin, and / or its predecessors, and / or its analogues in the water solution (less than 3%) as an agent for u0441u0445u0432u0430u0442u044bu0432u0430u043du0438u044f and the b u0435u0442u043eu043du0430 thusgreatly increases the viscosity and resistance to flushing the cement mixture.thus, the new cement mixture improves the physico-chemical and bacteriological properties of normal concrete, and of particular interest is the significant increasethe compression resistance and the viscosity or the relative changes in these indicators are less compared with a mixture containing water.it also increased significantly from the early stages, the 3d stability of concrete, thus increasing its resistance to flushing.as well as u043au043eu0440u0440u043eu0437u0438u043eu043du043eu0441u0442u043eu0439u043au043eu0441u0442u044c metal elements loaded in it, since certain data elements significantly protected from wear.
