The issue of treating Acid Mine Drainage (AMD) has become a significant environmental concern for the global mining industry in recent years. AMD is generated by leaching sulfur-containing minerals (mainly pyrite, FeS2) mine tailings, which react with atmospheric oxygen to form highly acidic solutions. These solutions contain heavy metal ions and pose risks water bodies, soil, human health. Moreover, presence been demonstrated contribute severe ecological damage, including impairment aquatic...
Natural gas leakage accidents frequently occur during pipeline transportation, and accurately identifying the type of failure is a technical difficulty. This paper proposes fault diagnosis method for natural based on 1D-CNN self-attention mechanism. Firstly, taking signal GPLA-12 as research object, 12 types faults were determined; secondly, basic model feature with self-learning built by using wide convolution 1D-CNN; then, mechanism introduced after pooling layer above to strengthen...
The impacts of steel slag (SS) and ground-granulated blast-furnace (GGBS) on the mechanical properties, hydration process, microscopic characteristics concrete were investigated in this study. results show that substituting cement with SS has a negative impact strength; however, partial replacement GGBS could produce positive effect by facilitating whole cement. improvement strength was small early stages (3–28 days) occurred mainly late (28–90 days). Meanwhile, heat flow cumulative...
As a new cement-matrix composite material, fiber-reinforced concrete performs excellently in freeze–thaw resistance, tensile and seepage resistance. Since resistivity can be used to evaluate the performance of concrete, basalt–polypropylene (BPFRC) was investigated this study. Various parameters such as fiber type, content, water–binder ratio were also analyzed. The BPFRC tested by an improved two-electrode alternating current (AC) method, differences analyzed using scanning electron...
A new type of cemented paste backfill (CPB) was prepared by using the bottom ash (BA) from a thermal power plant as an aggregate, alkali-activated slag binder, and air-entraining agent admixture. Based on central composite design (CCD) response surface method, mix ratio optimized, scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS) performed optimal ratio. ImageJ software utilized to determine porosity experimental samples at various curing ages. The results indicate that...
Abstract The flexural behavior of basalt fiber (BF)/polypropylene (PF)-reinforced concrete (BPRC) was investigated. When the content BF and PF is 0.1%, addition fibers increases compressive strength concrete. A 0.1% has most obvious effect on improving strength, but a hybrid 0.2% exhibits negative strength. can increase expansion tortuosity fracture cracks, thus enhancing ductility with are beneficial to However, crack decrease matrix improvement proportion also decreases. mixed, compared...
The volume expansion of reinforcement corrosion products resulting from the steel embedded into concrete causes concrete’s protective layer to crack or spall, reducing durability structure. Thus, it is necessary analyze cracking caused by corrosion. This study focused on occurrence non-uniform in a natural environment. characteristics rust were used deduce unequal radial displacement distribution function around both angular and non-angular bars. Additionally, relationship between ratio bar...
