INNOVATIVE DEVELOPMENT OF CONSTRUCTION MATERIAL SCIENCE IN THE CONTEXT OF SOLVING THЕ PROBLEM OF HYDRATION IN THE C ─ S ─ H SYSTEM

Abstract

Innovative development of technologies of construction composite materials directly depends on understanding a mechanism of water binding in the mineral system. Aqua-complex [2TO ₃ ─ H ₂ O ─ M ⁿ⁺ M ^m+ O` <sub>4</sub> ] (where T is, mostly, Si and other four-valent cations: C, Ti, etc., M <sup>n+</sup> is uni- and bivalent cations: Na, Fe <sup>2+</sup> , etc., M <sup>m+</sup> is multivalent cations: Al, Fe <sup>3+</sup> , etc., O` is O and other volatile elements: Cl, S, etc.) is a solution to the problem. Aqua-complex was first found as a result of studying the problem of water ̶ natural mineral matter binding. Further, the role of aqua-complex as a law of evolution of the terrestrial matter was justified by the complex of geological-mineralogical and experimental data. Verification of the concept of aqua-complex, besides geological sciences, was made based on various natural sciences (pedology and others), as well as practical applications. The concept of aqua-complex unravels the nature of cement binding properties and gives an answer to the key problem of construction material science: why as a result of water sealing of a system of fine-dispersed mineral components (C - S system) their consolidation and formation of monolith, an artificial analogue of rock matter, occurs? The knowledge of the nature of solidification in the C ─ S ─ H system allows as much as possible optimizing the technologies of production of the building materials with the specified properties. This is shown in the case of the development of construction composites based on concrete.
