Physical and Mechanical Properties of Rural-Road Pavement Concrete in South Korea Containing Air-Cooled Blast-Furnace Slag Aggregates

The purpose of this study was to assess the physical and mechanical properties pavement concrete for rural roads South Korea made with air-cooled slag aggregate, which is an industrial byproduct. This assessed chemical according following performance requirements based on design criteria Ministry Agriculture’s Agricultural Production Infrastructure Maintenance Business Plan Expressway Corporation’s Highway Construction Specialized Specifications: slump 80 mm or greater, air content 4.5 ± 1.5%, compressive strength at least 21 MPa, splitting tensile 4.2 a chloride penetration resistance less than 4000 C. slump, content, strength, flexural ion permeability aggregate-containing concretes were measured. aggregates provided necessary presented no environmental issues. Furthermore, met target values. decreased increased increasing amounts aggregate. Mechanical testing containing aggregate established that they road pavement.
