• Sodium silicate solution was impregnated in lightweight aggregates (LWA). Impregnated LWA were coated then embedded concrete specimens. Strength regain remarkable for specimens with the LWA. Capillary water absorption significantly improved produced rich silica C–S–H to heal cracks. This study investigated a technique of impregnating potential self-healing agents into (LWA) and performance mixed Lightweight diameter range 4–8 mm sodium as agent. Concrete containing control pre-cracked up...
Abstract Autonomous healing of cracks using capsule-based systems is emerging as a promising solution to restore durability and strength damaged structures. For satisfactory self-healing efficiency, both capsule geometry dosage are be determined for the concrete mix proportion. With previous research being performed on efficiency different shapes crack patterns, this paper introduces quantitative numerical solutions optimal capsules required completely repair in three-dimensional model...
Gaza Strip, a heavily populated area, is narrow coastal strip on the Mediterranean Sea (360 km2). Groundwater only source of drinking water for majority population. However, many human activities greatly threaten groundwater resources and nitrate was still major pollutant. Khanyounis, one southern governorates suffering from highest concentration in aquifer. We used three-dimensional MODFLOW model, paired with MT3D to simulate part aquifer including Khanyounis governorate. Subsequently,...
