Keywords: visualization of flowable concrete, 3D depth sensor, Kinect, digital image processing, coordinate transform, slump flow test, concrete workability test, structural health monitoring during construction, automated measurement in construction 1. Introduction Monitoring the workability of freshly mixed concrete is necessary to ensure that the concrete is properly placed during construction and that adequately hardened strength is achieved after construction [ 1 ].
Both are related to structural integrity, safety, and construction productivity. For the safe and easy construction of high-quality concrete structures, it is necessary to use fresh concrete with proper workability.
Workability such as flowability, viscosity, yield stress, and resistance to material separation required at construction sites depends on the type of target structure, the spacing of reinforcements, dimensions, cross-sectional shape, construction method, and concrete pumping distance [ 2 ].
Monitoring of concrete workability [ 3 , 4 ], as well as strength [ 5 , 6 , 7 ], is regarded as a key technology in the long-distance transport of concrete required for high-rise buildings and long-span bridge construction. In the field of innovative concrete 3D printing technology in the construction area, workability control will be critical to ensure consistent material properties and structural performance [ 8 , 9 , 10 ].
In the field of concrete materials, highly flowable self-consolidating concrete SCC is attracting attention for its ability to fill congested rebar spaces in a formwork under its own weight without using a vibrator.
The characteristics of SCC are filling ability, passing ability, and stability [ 11 ]. The use of SCC can increase the construction efficiency because it can improve the quality of a concrete structure, reduce the labor requirement, and increase the construction speed.
The use of SCC is expected to increase as the complexity of building design and the number of high-rise buildings increase [ 4 ]. As a standard test method to assess the filling ability of flowable concrete, the slump flow test shown in Figure 1 has been established [ 12 , 13 , 14 ].
It is the simplest and most widely used test method for SCC [ 1 ]. The results of this study sizes Table 2 lists the details of the mix proportions.
