Experimental study on the depth of abrasion in hydraulic structures using samples of geopolymer concrete

Large quantities of concrete can be destroyed in various hydraulic structures, such as dams, spillways, and stilling basins, due to the long-term effect of water-borne solids. The durability of hydraulic structures is largely determined by the resistance of the concrete surface to mechanical abrasion. Hydro-abrasion is the term for the surface damage caused by a continuous material removal process induced by the impact of water-borne solid particles. This type of progressive deterioration of concrete surfaces is seen in practically all hydraulic constructions, including to varying degrees. Ordinary Portland Cement (OPC) could be replaced with Geopolymer Cement (GPC). Geopolymer technology has the ability to minimize OPC production's global greenhouse gas emissions. There has already been a lot of work and study done on geopolymer over the last few decades, and it is now conceivable to commercialize this technology. However, more research into the qualities of geopolymer concrete and its capacity to offer study and long-lasting materials is required to ensure that it becomes commercially available and utilized around the world. Abrasion resistance in hydraulic structures is one of the features that has been investigated and worked on experimentally in the laboratory. In this study, three different grades of normal, standard and high-strength GPC were fabricated, in addition to their counterparts of OPC concrete, with different ages (3, 7 and 28) days and the corrosion resistance was tested with a non-standard device (water-jet method) experimentally. Test results revealed that geopolymer concrete outperforms conventional cement-based concrete in terms of wear resistance in all three grades.
