- Synopsis
- This paper outlines the state of the art report on construction performance and issues related to examination and inspection systems for fresh concrete. We identified the problem and limitation of the present evaluation system of construction performance and issues related to the current slump test, and carried out a factor analysis (interrelation diagram) on quality control issues and quality problems with regard to the construction of civil engineering structures. Based on this understanding and results, this paper describes measures to ensure workability needed for construction. This paper also proposes experimental methods for examinations and inspections related to the design of concrete mix proportions as alternatives to the slump test.
