Internet of Things-Based Concrete Curing Invention for Construction Quality Control
Table 3
Experiment A procedures.
Steps
1
Prepare 3 sets of horizontal fresh concrete (0.4 m width × 0.3 m height × 0.1 m depth)
2
Cure 3 sets of concrete by air, IoT device, and hand, respectively
3
Measure and record initial concrete temperature and surface dampness
4
Observe and record the initial appearance of concrete surface
5
Observe and record the concrete surface bleed water every 10 minutes; at the same time, measure the temperature and surface dampness until it reaches final set (225 minutes after placing)
6
Measure the surface dampness and temperature of 3 sets of samples as they just reach final set
