The reduction in the activity of Portland-cement under the impact of pre-hydration caused by environmental factors is considered. With the use of experimental methods the influence of adsorption moisture on the kinetics of heat emission and phase composition of Portland-cement stored in hermetic and non-hermetic containers has been studied. It is established that under normal conditions (21±1°C and 55±5% of humidity) the effect of pre-hydration causes a decrease in the concentration of active components of cement and an increase in the concentration of amorphous phase, Portlandite and calcium carbonates (aragonite and calcite). It is revealed that phases C3S and hemihydrates gypsum are most affected by the adsorption moisture. The peculiarities of changes in the heat flow and total heat emission at early stages of the hydration of the samples stored under different conditions during the year were studied using the method of isothermal calorimetry. It is established that only a slight decrease of activity is observed for the samples stored under hermetic conditions, but at the same time the activity of analogous samples stored under non-hermetic conditions reduces proportionally to the time of storage.

Foamed heat insulating materials notable for their technical and operation characteristics have been obtained. The fly ashes of OAO “Irkutskenergo” of different chemical compositions is used as fillers of polymeric compositions; modified phenol-formaldehyde resins of different brands are used as a binder. The maximum content of fly ash in the material is 55 wt.%. Structural features of the foam material are considered. When the content of the filler is over 30%, pseudo-crystallites of various shapes with round and oval pores of different sizes are observed. Depending on the content of fly ash in the composition, the diameter of cells changes: when the filling is 30%, the diameter of cells is 2–200 mkm, 35% – 5–300 mkm, 40% – 5–400 mkm. The results show that the developed heat insulating material has following characteristics of combustibility – G1, V2, D1, T1 that makes it possible to say that it can be safely used as a contemporary insulation material. Results of the study allow us to draw conclusions about prospects of using this material in building industry.

The stability of various types of epoxide binders (epoxy-anhydrate and epoxy-amine) for polymer-composite reinforcement (PCR) in the alkaline environment of the concrete (simulated with the help of water-cement suspension) at 23°C and 80°C has been studied. It is established that the sorption of water solution Ca(OH)₂ is accompanied by destruction of polymers and leads to the plasticization and, as a result, to the decrease in micro-hardness and to the increase in bending resistance. It is also established that epoxy-amine binders are more resistant to the alkaline environment than epoxy-anhydrate. Nano-modification of binders increases the stability of the PCR in the concrete and its durability.

Information about the beginning of the production of loose-fill foam glass in Russia is provided. It is shown that the use of foam glass makes it possible to build energy saving, eco-friendly buildings. Main characteristics of the foam glass gravel of 140 kg/m³ density are presented. The technology of loose-fill foam glass production is described. According to the manufacturer the use of foam glass as loose-fill heat insulation, under the foundation slab for example, makes it possible to reduce the construction budget at this stage of works by 35%. The economy is realized due to reducing the cost of earth works and foundation base works.

The influence of sodium silicate solution mass transferring inside raw granules of foamed glass during the drying process was investigated. It is shown that the transfer of dissolved components to the surface of the granules takes place during the drying. Admixing of components facilitating the sol-gel conversion of the silicate solution and solidification of granules into the initial composition prevents the migration of Na⁺ ions and opens up new technological possibilities.

The development of foamed glass technology is discussed in the article. It is shown that the gap between scientific developments and the practice of foamed glass manufacture, as a building material, has the principal character that does not allow, in the foreseeable future, to hope for the development of foamed glass manufacture technologies as well as organization of enterprises which are able to produce the competitive material in the field of industrial and civil construction. The market non-competitiveness of foamed glass produced according to the classical powder technology from the special glass is substantiated. Assumptions about technical solutions and technology trends that will make it possible to produce the material in demand at the building materials market are made.

Issues of improving systems of hot bitumen dosing are considered. The design of the modernized bitumen batcher containing the vertical cylindrical element located inside the receiving container and connected with the S-shaped strain meter is presented. The principle of bitumen dosing in the upgraded batcher is in the measurement and scaling of bitumen weight displaced by the vertical cylindrical element when filling in the receiving container. The possibility of additional calculation of the density of the dosing material, which is carried out using the vertical cylindrical element of an improved form is shown. The measured value of the concrete density inside the receiving container of the batcher is used for the adaptive control over dosing. It is noted that the use of presented schemes of bitumen weight measurement simplifies the process of modernization of existing batchers and reduces the costs of reconstruction of operating asphalt-concrete plants.

Results of the study of physical-technical properties of mineral-polymers and thermoplast-concrete under development, as well as the data on changes in the strength properties of these concretes depending on the content of the polymer component in their compositions, are presented. In the course of the analysis of results it is established that the increase in the content of polymer binder in composite composition is accompanied by the decrease in compressive strength and by increase in bending resistance. Along with this, there is an increase in the concrete elasticity which as the ratio of R_bending/R_compression has the following values for concretes with the compressive strength of 75–85 MPa – 0.20–0.23 and for concretes with the compressive strength of 45–55 MPa – 0.40–0.50. It is also established that elastic mineral-polymer-concretes with their closed porosity in comparison with cement concretes have smaller values of water absorption, smaller decrease in the strength in the course of humidification and significantly higher frost-resistance.
