Concrete Structures and Construction Course
Introduction:
Around the world, concrete is employed in a variety of ways. Recent developments in material science have introduced novel materials or admixtures to be added to or substituted with traditional concrete components in order to improve the qualities of concrete. These materials could be used to build new concrete structures or to fix already-existing ones. If not handled correctly, these products could be ineffectual or perhaps more harmful than beneficial.
Course Objectives:
The goal of this course is to provide participants with an advanced understanding of the properties of traditional and emerging materials used in civil engineering construction, newly developed construction materials, and test methods for different conventional and advanced materials used in concrete and steel construction. The course covers modern field measurements such as concrete strength, concrete uniformity and others. Upon the completion of this course, the participant will be able to select the appropriate material to achieve particular design goals and recognize the governing standards, performance criteria, and laboratory and field tests for characterizing such materials. Quality control and quality assurance approach is handled through the course. Focus on the approach of workable preventive measures for the decay and deterioration of structures, and the use of innovative technology and new materials is also introduced.
Who Should Attend?
This course is designed for senior engineers, projects engineer, design engineers, and Supervisors with professional knowledge.
