Inorganic coatings are widely used to protect concrete structures due their high durability. However, improving the antipenetration performance and bonding strength of these remains a challenge. This study aims develop an inorganic coating with excellent performances using high-carbonation reactivity γ-dicalcium silicate (γ-C2S) delve into underlying mechanisms. γ-C2S exhibits 5.25 MPa substrate by absorbing CO2 demonstrates great durability, retention 90% after 28 days irradiation. Compared noncoated concrete, capillary water absorption coated has decreased 58%, while contents free total chloride ions in have 68 60%, respectively. Furthermore, phase assembly pore structure were investigated understand mechanism. A connecting section was revealed, which positively impacts between substrate. coating-to-substrate interface interaction further explored elucidate mechanisms

Geopolymer-based grouting materials often have a higher early strength, better durability, and lower environmental impact than those of traditional cement-based grouts. However, existing geopolymer grouts face common challenges such as rapid setting low compatibility with treated substrates. This study develops new material using industrial byproducts to overcome these limitations while optimizing performance for reinforcing silty mudstone slopes. The base used were ground granulated blast furnace slag (GGBFS) zeolite powder, calcium lignosulphonate (CL) serving the retarding agent NaOH alkali activator. investigation focused on effects mix ratio water–binder time, flowability, bleeding rate, concretion compressive strength material. Scanning electron microscope (SEM) X-ray diffraction (XRD) analyses employed examine action mechanism components in slurry. one-factor standard deviation method Grey Relational Analysis (GRA) assess influence each component slurry indices correlation between index its optimal ratio. Subsequently, was ascertained. results indicate that time is positively correlated powder CL dosages ratio, it inversely related dosage. flowability significantly enhanced increasing dosages, but decreases at dosage insight crucial workability under various conditions. grout powder:GGBFS:CL:NaOH = 30:70:5:7, 0.6. Compared commercial materials, this comparable mudstone. reduces problem stress concentration grout–rock interface due differences, thus effectively reducing risk secondary cracking interface. These findings provide solution repairing fractured
