AbstractAbout AuthorsReferences
A non-linear cell mathematical model of drying kinetics of long-measuring sheet material by parallel gas flow is proposed. The model allows calculating the drying kinetics based on the local state of material and gas and takes into account longwise heat conduction and moisture conduction. It is shown that the reverse of gas supply at rationally chosen moments of time allows considerable decrease of the non-homogeneity of moisture content distribution during drying process.

Models establishing the relationship between the total porosity of cement stone and its properties such as the ultimate compressive strength, E-modulus and creep coefficient are proposed. Compliance of models with the experimental data is shown. Models make it possible to predict changes in the strength and deformation properties of cement stone depending on changes in its total porosity under the influence of prescription or technological factors.

AbstractAbout AuthorsReferences
The application of fiber reinforced polymers in construction became an important research topic in construction. Reinforced polymers have many advantages such as high tensile strength, corrosion resistance, light weight and non conductivity. This study presents an experimental investigation into the direct shear behavior of concrete, reinforced using basalt fiber reinforced polymer (BFRP) bars, by testing Push-off specimens. The main objective of the study is to compare the behavior of concrete S-shaped push-off specimens reinforced using ordinary mild steel bars or BFRP bars to the plain control specimens. Twelve specimens were molded and tested under compression force. They were divided into four groups differing in the type and detailing of their main reinforcement. Based on the obtained results, the equations used to predict the shear capacity of reinforced concrete were modified to suit the reduced stiffness of the BFRP.

AbstractAbout AuthorsReferences
The paper presents the researching results of deformation properties of the high-strength lightweight concrete with hollow microspheres. The method of increasing the fracture toughness of high-strength lightweight concrete with aluminosilicate microspheres by using the modifier as a coupling agent on the surface of the microparticles of aggregate is proposed. The hollow microspheres are perspective filler for lightweight concrete with high performance characteristics; the increasing of content of the spherical microparticles in the concrete composition promotes to forming close-packed structure with low deformations. The coefficient of fracture toughness of the high-strength lightweight concrete is comparable with the same parameter for fine-grained high-strength heavy concrete (more than 0.1) and is limited by strength characteristics of micrometric particles of aggregate. It is to create the active iron-silica shell on the surface of the hollow filler, which interacts with the major components and products of the cement hydration and reinforces the phase boundary. The proposed method of modifying allows to reduce the longitudinal and transverse deformations of the high-strength lightweight concrete at 7–12% and 8.5–16.5% respectively. The elastic modulus of the high-strength lightweight concrete is 6–8.5 GPa, and Poisson’s ratio is 0.08–0.14. The nanomodifier reduces the intensity of the cracking under the influence of shrinkage stresses of high-strength lightweight concrete by 56.9%.

AbstractAbout AuthorsReferences
Implementation of the law of the affinity of structures allows to create effective systems with anisotropic hardening of the composite, which includes the foundations for responding to the changing conditions of synthesis and service. It has been established and proved that within the system new fomations are synthesized and nano-, micro- and macrostructure is created, possessing self-healing ability in mending defects, caused by a particular range of operating loads. When designing the composites of the future it is advisable to use the provisions of the law of the affinity with the creation of highly reliable internal structure of the composite. Theoretical and practical approaches should be the prerequisite for the creation of a new class of “smart” construction materials with isotropic structure and effective properties.

AbstractAbout AuthorsReferences
Results of the development of lightweight and ultra-light slurries having a low density with sufficient strength due to optimizing their structure with due regard for the geometric and physical-mechanical characteristics of components are presented. As a filler in these mortars, it is proposed to use hollow glass microspheres and as a binder – ultrafine cement. Because the hollow glass microspheres are more than 10 times lighter than cement, the increase in their share in the volume solution will reduce its average density. At that, it is necessary that the microspheres are characterized by maximally dense packing and are surrounded by a dense matrix, that is, their volume fraction in the bulk solution would be maximal. It is expected to achieve this fact by reducing the thickness of layers of the cement matrix, which is achieved by more fine dispersing the cement particles, or replacing the Portland cement by a new high efficient mineral binder – «Mikrodur». As a result of optimization of the structure with due regard for the geometric and physical-mechanical characteristics of components and their energy states, lightweight and ultra-light cement mortars with high construction and technical properties have been be obtained.

AbstractAbout AuthorsReferences
The information on basic advantages of the monolithic construction technology is presented. Issues of improving qualitative and technological characteristics of ready-mixed concretes including durability and crack resistance are considered. Compositions of concrete composites with water tightness W16 and frost-resistance F300 have been developed with the use of expanding agents and complex of chemical additives. The results of tests of compositions of concrete mixes for slump retention vs. time and changing the air entrainment when agitating in the truck-mounted mixer are presented. Ii is shown that expanding agents in cement composites create the dense structure, reduce the permeability including diffusion, which prevents the corrosion of concrete and steel reinforcement.

Results of the study of influence of dispersity of quartz-feldspar waste and a diopside concentrate in ceramic masses on the sintering and properties of building ceramics are presented. It is established that reducing the dispersity of quartz-feldspar waste in the samples entails the fire shrinkage, decrease in the optimal burning temperature, strength growth. The diopside concentrate with dispersity of 150 mkm in the composition of ceramic masses ensures the obtaining of a non-shrink building material with high physical-mechanical properties.
