“…Wonsuk et al [47] studied slag shotcrete and found that under high-temperature conditions, the output of CO 2 in cement decreased and the early strength of shotcrete was significantly improved. The linear expansion value of slag shotcrete is very low and the pozzolanic activity is high, which is conducive to the development of shotcrete strength at the later stage [48]. As shown in Figure 5, D'Aloia et al [49] carried out a numerical simulation on the cracking performance of tunnel lining shotcrete.…”

High temperature is recognized as one of the extreme environments in the application of shotcrete which significantly deteriorate the performance of shotcrete. This paper reviews the mechanical properties and microstructure of shotcrete under high temperature. First of all, this paper reviews the cause of formation of high ground temperature. Based on these causes, the author establishes a heat transfer model with a spiral shape by introducing a multidimensional morphological formula into the heat conduction process. Then, the paper reviews the influence of high temperature on the mechanical and micro properties of shotcrete, the cooling technology under high temperature, and the optimization research technology of shotcrete. The author discusses the influence of high temperature on the thermal parameters and the deformation of shotcrete from the perspective of thermodynamics. Multiple studies have shown that the irregular movement and disorderly overlapping of molecules in the shotcrete caused by the high temperature environment result in the premature termination of the hydration reaction of cement in shotcrete. Finally, the author suggests the challenges of high-temperature shotcrete in term of the process structure, performance optimization, and application in special engineering fields. The research in this paper intends to give guidance to those conducting shotcrete research under high temperature, and to promote the further development of shotcrete technology.

“…[10]. Mymrin, V. et al attempted to use industrial waste ferrous metal cooling slag and lime production waste as a binder for natural loamy soil in road subgrade, and the feasibility of the proposed scheme was confirmed by simulated numerical tests [11]. Hadel, O. et al explored whether steel sand-containing asphalt granules could be used as a substitute for conventional road materials, but the test results showed that the proposed method could be applied for pothole repair but could not be adopted in road milling and road base paving [12].…”

In the face of annual highway construction and highway maintenance projects, traditional road materials and road testing technology are difficult to meet the current highway construction needs. Based on this research background, the article first discusses the three-dimensional ground-penetrating radar nondestructive testing technology, analyzes the detection principle from the fluctuation equation of electromagnetic wave, the propagation characteristics of electromagnetic wave, and the propagation speed in the medium, and specifically analyzes its detection performance and application in the detection of the thickness of the structural layer. Finally, some sections of the Shanzhan Expressway are chosen as test objects and test experiments are designed and implemented. The test results show that the strength of the road material with water water-reducing agent increases compared to the material without water water-reducing agent. By using red mud instead of cement, road materials can have a relatively high strength. Therefore, using red mud as a substitute for conventional materials is entirely feasible and can save costs. The cracking rate of the highway was reduced by using the “leaching recycled” material, and the small cracks of less than 2mm were basically sealed, while the cracks of more than 2mm were alleviated. There is no water seepage on the pavement at 28 points of the 7 sections tested, so the “leaching regeneration” material has a better waterproof effect on the highway pavement.

“…Since landfilling these wastes can lead to environmental pollution, many efforts have been made over the past two decades to use these steel slags in construction applications, reducing environmental impact due to their resource-conservation and energy-saving properties. For example, the utilization rate of these slags reaches 98,4% in Japan, and 87,0% and 84,4% in Europe and USA, respectively [2]. Although Kazakhstan produced 355 thousand tons of steel in 2021, the utilization rate of steel slags is too low [3].…”

Basic oxygen furnace slag (BOFS) is a waste product generated during steel production. The utilization of BOFS in construction applications is considerably limited because of its inherent characteristics leading to volumetric expansion behavior caused by the chemical reaction between free lime (f-CaO) and water. The main objective of this paper is to investigate the material properties of normal mortar and geopolymer mixtures that contain BOFS aggregates. Three different aggregates were used to compare their performance, including siliceous river sand, fresh BOFS aggregate (within 1-month age), and stockpiled (more than 5-year age) BOFS aggregate. Test methods included a compressive strength test, accelerated mortar bar expansion test, and thermal conductivity test. Test results revealed that (1) geopolymer mixtures containing BOFS aggregate had comparable compressive strength with mortar mixture with river sand, (2) geopolymer mixtures have very low volume expansion, (3) thermal conductivity of geopolymer mixtures having both river sand and BOFS was lower than normal cement mortar mixture containing river sand. Therefore, geopolymer technology seems a key solution for converting BOFS slag into valuable construction materials. Therefore, a geopolymer mixture containing BOFS aggregate can be used as an energy-saving material.
