Chapter
Nanomodification of building materials requires the involvement of theoretical knowledge to justify the choice of the type of nanomodifier, as well as experimental studies to establish the method of its introduction, concentration and distribution in the volume of the composite. Failure to comply with this leads to the occurrence of cases in which...
Article
The paper presents the derivation of a strength equation of composite materials that can be represented in the form of polydisperse systems. The theoretical analysis shows that the process of composite material structure formation is anti-persistent. A structural transition was revealed at a volume defect concentration of 0.65, which leads to a sha...

Improving the properties of cement building materials is possible with the use of modifiers, including nanoscale ones. Such nanomodifiers include hydrosilicates of zinc and copper. The increase in the performance characteristics of nanomodified cement composites is due to changes in the chemical composition of the resulting cement stone, in particu...

Studies of the advantages of sulfur-asphalt concrete with toxic gas emission neutralizers show that the use of neutralizers reduces the amount of emission of these gases and improves the environmental problem of the use of sulfur-asphalt concrete. Zinc oxide and zinc oxide are not effective in neutralizing hydrogen sulfide and sulfur dioxide. Reduc...

Due to high importance of cement concrete for construction industry it is essential to discover new ways towards increasing the durability of the concrete. The problem of low durability is of highest significance in case of hot and humid operating conditions. We have discovered that some biocidal modifiers are able to not only to solve their primar...

Due to high danger of mold fungi spores for humans, it is necessary to develop new fungicidal building materials, especially – materials that help to maintain biosafety in interior rooms. One of such materials is the fungicidal gypsum binder. The aim of the present work was to study the process of structure formation of gypsum in case of the presen...

Currently, there is a strong need of high performance multi functional materials in high-rise construction. Obviously, such materials should be characterized by high strength; but for interior rooms biosafety is important as well. The promising direction to obtain both high strength and maintain biosafety in buildings and structures is to manage th...

Due to the growth of load on automotive roads, modern transportation engineering is in need of efficient paving materials. Runways and most advanced highways require Portland cement concretes. This makes important the studies directed to improvement of binders for such concretes. In the present work some peculiarities of the process of Portland cem...

Currently, many building materials for interior finishing are based on gypsum as a binder. Usage of gypsum allows to significantly simplify both the production of building materials and to increase the operational properties related to energy efficiency. This makes important the studies directed to the improvement of gypsum-based binders. In the pr...
Conference Paper
There is a need of biocidal building materials during production of constructions in civil and industrial engineering. It is beneficial to produce such materials on the base of composite binder with biocidal silicon -metal modifier. The chemical composition of the specific modifier was examined and some results are presented in the gi ven article....
Conference Paper
The present work is devoted to the synthesis and experimental study of zinc hydrosilicates. The possibility of low-temperature synthesis of such hydrosilicates from zinc acetate and silicic acid is demonstrated. The silicic acid was synthesized in presence of acidic Fe(OH)3 sol. It is found that the size of the nanoparticles is in the range 10-30 n...
Article
We have studied the effect of a barium hydrosilicate-based modifier on the phase composition of Portland cement hydration products. The results demonstrate that the addition of a modifier containing barium hydrosilicates, silicic acid, and calcium carbonate makes it possible to reduce the nucleation rate of crystals of new phases during the inducti...
Article
The development of new types of composite materials is an important aim for construction. Nanoscale admixtures allow efficient control of the composition and properties. Results of experimental investigations concerning effect of admixture of nanoscale barium hydrosilicates to the chemical composition of hydrated portland cement are discussed in th...
Article
The present work is devoted to the examination of new radiation-protective binder for special-purpose composite materials. The mixture for such advanced binder is developed. The mixture includes portland cement together with special component – barium hydrosilicates. The latter are micro-sized mineral admixtures which are synthesized by means of lo...
Article
One of the promising directions of quality improvement of building materials (based on various binders) is to use hydrosilicates of calcium and barium. In particular, it is known that the application of calcium hydrosilicates can improve the compression strength in two or three times; the fracture toughness can be increased in two times and more. P...
Article
Radiation safety of the rooms with X-ray sources often achieved by means of creating protective coatings. Such coatings are made of special mortar containing barite. There is the alternative for barite – barium hydrosilicates. It is advisable to synthesize barium hydrosilicates from available components – sodium hydrosilicates and soluble salts of...
Article
The volumetric rate of filler affects the type and structure of chemical products emerging during the hardening process of binders and composites based on barium hydrosilicates. It is shown that by means of using the inert filler it is possible to change the composition of the hardened material. In particular, instead of BaO•2SiO2•4Н2О formation, t...
Article
The water glass can be used as a binder for the design of water-resistant radiation-protective building materials. In the present work the possibility of hardening of such materials by barium chloride is investigated. The chemical reactions which can take place during the structure forming and lead to the formation of barium hydrosilicates are pres...
