Internet of Things-Based Concrete Curing Invention for Construction Quality Control

Table 9

Curing technologies comparison.

Methods	Concrete curing boxes	Concrete curing tanks	IoT-based concrete spraying devices
Usage	Provides continuous storage for long periods in an environment kept at constant temperature and high humidity	Provides continuous immersion in water for long periods; the water temperature is kept constant	Spraying water as necessary to provide a constant concrete water content over time
Advantages	Reliable all-round control of concrete test specimen’s environment	Cost-effective alternative to specimen environmental control; a set water temp. 100% RH	Adaptable, cost-effective alternative to full-scale on-site concrete
			Combined monitoring and analysing function to decide the amount of water spray
Disadvantages	Only applied for small-sized concrete	Only used for small-sized concrete pieces; usually quality control test specimens	Specimens monitored should not be in direct sunlight, as radiation effects are not allowed for
