“…In addition to bricks, concrete is also highly used in the construction industry. Prusty et al [34] observe that concrete comprises a mixture of cement, fine aggregate, and coarse aggregate, all of which are derived from natural resources. Subsequently, as the demand for housing increases, significant pressure is mounted on the non-renewable natural resources, thereby sparking research on the use of alternative agro-waste materials to produce concrete.…”

The construction sector, in modern times, is faced by a myriad of challenges primarily due to the increase in the urban population and dwindling natural resources that facilitate the production of construction materials. Furthermore, higher awareness on climate change is forcing companies to rethink their strategies in developing more sustainable construction materials. Diverse types of agro-waste ranging from rice husk ash (RHA), sugarcane bagasse ash (SCBA), and bamboo leaves ash (BLA) among others have been identified as potent solutions in the development of sustainable construction materials. In this review paper, six different construction materials, made using agro-waste products, are examined. The materials include brick/masonry elements, green concrete, insulation materials for buildings, reinforcement materials for buildings, particleboards, and bio-based plastics. The main criterion adopted in selecting the materials regards their popularity and wide-scale use in modern construction applications. Additionally, as this research emphasizes identifying alternative approaches to develop sustainable construction materials, the focus is directed toward mainstream materials whose continued use has an adverse impact on the environment. The findings obtained from the review showed that the use of agro-waste to develop sustainable construction materials was effective, as the developed materials adhered to established building standards. Therefore, this indicates that agro-waste materials have the potential to replace conventional construction materials and hence achieve economic, environmental, and social sustainability in the long run.

“…Continuity is important for the solid phase and pH of liquids, moisture content and constant temperature are important for the pore space. A comprehensive approach to capillary-porous structure in concrete makes it possible to take into account formation of its solid phase and pore space on which physico-mechanical and deformation properties of concrete depend [1,2].…”

“…The tool is used as a substitute for cyanide compounds in electrolytes, in humane medicine for the disinfection of surgical instruments, equipment, drying cabinets, rooms. Due to their ability to form a film around concrete particles, they are also a good filler to reduce pores in concrete and particle binding [5,6].…”

The results of studies to determine the effect of titanium dioxide nanoparticles (nanoTiO 2 ), finely dispersed anatase crystalline titanium dioxide (anatazTiO 2 ) and surface-active substances (surfactants) on the compressive strength, degree of permeability and thermal stability of concrete samples are presented. Adding particles of nanotitanium, anatase titanium and surfactants up to 2 % to cement accelerates the hydration process and increases the strength of concrete, and also has a strong effect on its microstructure.As a result of the studies, it is experimentally proved that the compressive strength of concrete increases with the addition of titanium dioxide (nanoTiO 2 ) nanoparticles by 23.2 %, finely dispersed anatase crystalline titanium dioxide (anatazTiO 2 ) by 21.7 % to 5 % concentration by weight. Original Research Article: full paper (2020), «EUREKA: Physics and Engineering» Number 2 20Chemical EngineeringIn addition, the introduction of these additives reduces the permeability of concrete. This is due to a decrease in the absorption of concrete by water with the addition of nanotitanium and anatase titanium. The introduction of additives from 1 % to 5 % by weight in concrete reduces the depth of chloride penetration by 10-15 times, compared with the control.The use of temperature-programmed desorption mass spectrometry (TPD-MS) method has shown that an increase in the percentage of TiO 2 nanoparticles to 5 % in concrete mixtures correlates with an increase in microporosity and dispersion level of these mixtures, which causes a shift in the peaks of intense gas evolution from the samples when heated to the side low temperatures (for example, carbon dioxide CO 2 ).The resulting concrete samples are planned to be used for the manufacture of floors in livestock buildings. The injected additives are selected because they are not toxic substances and, in contact with the biological environment of livestock buildings (urine, feces), will not react with them.
