The mechanism of formation of chaotically diversified difficult structure Accepted 27 May 2016 is described. Chemical interactions of cement with active components of diffusion in steam Available online space are examined. Measures for receiving conditions under which the volume of products of 28 May 2016 Keywords reaction will be equal to the volume of the reacted alkaline components of a cement stone are Corrosion offered. High-quality and quantitative changes in a pore space which are irrespective of Concrete density and the relative molecular mass of reaction products are described. Besides movement Capillary and distribution of gaseous products of reaction in volumes of a cement stone are simulated. Carbonization time Reasonable integrated dependences of influence of aggressive environment on various types Mathematical model of concrete surfaces are given. The methods of corrosion control offered in article allow substantially
