One of the priorities of modern construction industry is to increase the heat-shielding properties enclosing structures and reduce construction costs. Solving these problems is possible through the use in the manufacture of insulating exterior walling and structuralinsulating non-autoclaved aerated concrete from technogenic waste, especially fly ahes and slag thermal power plants.
The basic principles of the sustainable development strategy in the cement industry. The example of JSC “Ivano-Frankivsk Cement” shows that the production of special eco-cement provides the implementation of progressive models of rational use of natural raw materials, fuel, electric energy with the minimal СO2 emissions in the cement industry. Also it allows the implementation of the practice of clean production. The comparison of the efficiency during the preparing of building mortar based on Portland cements and low-energy cements was conducted.
Finishing mortars for decorative and protective facade coatings where natural kaolin is a major component were developed. The chemical and phase composition and microstructure of kaolin were investigated. Ultrafine kaolin (SSA = 1,58 m2/g) actively participates in the formation of phase composition and microstructure of the cement matrix of finishing mortars. Nanoscale systems of clay minerals due to plasticizing effect and filling influence provide improved adhesion-cohesive properties of finishing mortars.
It was developed fundamentally new concept of creation of multifunctional purpose concretes using composite zeolite-containing Portland cements with optimized particle distribution and modification by chemical admixtures. It was established that the optimal content of fine zeolite and limestone additives provides obtaining of composite zeolite-containing Portland cement with high strength at early age. The results of technological properties of concrete mixtures, physical and mechanical properties of concretes based on composite zeolite-containing Portland cement are presented.
