“…The significant benefits of such an approach are the application is very simple and significant amounts of waste can be consumed. Immobilization of hazardous waste materials of different origins in the construction industry is well described in the literature [16][17][18][19][20][21][22]. However, comprehensive research must be carried out prior to application as wastes of different origins, deposits, lots, or treatment may have completely opposite properties.…”

Solving problems with hazardous waste materials is of crucial importance today. In the presented study, the application of waste vitreous enamel as a cement replacement up to 30% in mortar and concrete production was investigated. The chemical and physical-chemical characterization of the starting material was performed, as well as a leaching test and physical-mechanical characterization of mortar and concrete mixes. Obtained results showed that, due to its chemical composition, the vitreous enamel used must be classified as hazardous waste. At the same time, it possesses pozzolanic properties and satisfies minimal criteria for use as a cement replacement. Testing mortars and concrete mixes indicate that waste vitreous enamel can be applied as a construction material for cement replacement in the maximal amount of 20%. The leaching test was performed in accordance with international standard EN 12457-2 on hardened mortar with a maximal cement replacement of 20%. The results showed that there was no significant release of toxic elements, i.e., that the practical application of hazardous waste vitreous enamel in the construction industry may be fully in line with environmental standards.

“…Currently, an important ecological problem is the global anthropogenic transformation of the natural environment caused by the intense impact of industry on natural ecosystems [ 1 , 2 , 3 , 4 ]. Reducing anthropogenic impact through the disposal of industrial waste is a priority area for the development of various industries [ 5 , 6 , 7 ]. The solution to this problem acquired particular importance for the enterprises of the fuel and energy complex, whose activities lead to significant changes in the earth’s surface, disruption of natural landscape complexes, the withdrawal of significant land areas, the development of erosion processes, as well as changes in the quality and regime of surface runoff [ 8 , 9 , 10 , 11 , 12 ].…”

Structural Formation of Soil Concretes Based on Loam and Fly Ash, Modified with a Stabilizing Polymer Additive

et al. 2022

Finding new ways of recycling production waste to improve the characteristics of various building materials is an urgent scientific task. This article substantiates the possibility of the disposal of fly ash in the composition of soil concrete, which is used in the construction of the structural layers of road pavements, foundations of buildings and structures, as well as sites for various purposes. The scientific novelty lies in the fact that the structure formation of soil concretes based on loam and fly ash and modified with a stabilizing additive is being studied for the first time. It was found that the investigated fly ash, according to its hydraulic properties, is classified as latent active and can be introduced into the compositions of road soil concrete modified with additives of various resources. The effectiveness of the complex method of stabilization, due to changes in soil properties as a result of the use of the binding and stabilizing additives of polymer nature “Kriogelit”, is shown. It was found that the optimal content of binder and fly ash in the samples was 8 and 10 wt.%, respectively. It was established that the use of the stabilizing additive “Kriogelit” makes it possible to obtain soil concrete with the highest strength (compressive strength 2.5 MPa, flexural strength 0.5 MPa) and frost resistance of at least F15. The microstructure, the degree of dehydration and carbonization, and the phase composition of the initial raw mixtures and soil concretes stabilized with the addition of “Kriogelit” were studied by methods of scanning electron microscopy, X-ray diffraction analysis, differential scanning calorimetry, thermogravimetry, and infrared spectroscopy. It was shown that organo-mineral complexes, with the participation of polymer and montmorillonite, are formed in stabilized soil concrete. It was revealed that structure formation is accompanied by the physical adsorption of the polymer on active centers of silicate minerals, carbonization, and hydration–dehydration processes. It was found that the reason for the increase in the strength of stabilized soil concretes is the hydrophobization of the porous structure of minerals, as well as the formation of calcium oxide silicate and dicalcium hydrated silicate. By the method of performing biotests with the test objects Daphnia magna Straus and Chlorella vulgaris Beijer, it was proven that the developed road concretes modified with the stabilizing additive “Kriogelit” do not have an acute toxic effect on the test objects and are safe for the environment and human health.

Concrete is a material that can easily absorb nuclear radiation, and in this process, the density of concrete is an essential factor in absorbing the rays. Therefore, due to performance limitations and thickness, heavyweight concrete is used. In this study, serpentine coarse aggregates (SCAg) and serpentine fine aggregates (SFAg) were used as a substitute for sand and gravel in heavyweight concrete containing lead slag to protect against gamma rays. Determination of mechanical properties (compressive strength, tensile strength, and ultrasonic pulse velocity), physical properties (water absorption and electrical resistivity), and shielding properties (shielding against gamma rays) were among the main objectives. The results indicated the positive effect of SFAg and SCAg on the shielding properties of concretes against gamma rays. The replacement of SFAg and SCAg with natural aggregates increased the density of the samples, which resulted in an increase in 3.8 to 42.9% in the linear attenuation coefficient against gamma rays. SFAg has a significant effect on gamma-ray attenuation, especially when these materials are made of high-density minerals, due to their property of reducing the pores in concrete.
