Description

Technical Field

[0002] Concrete curing is to artificially create certain humidity and temperature conditions so that the newly poured concrete can harden and increase its strength normally or accelerate its hardening. The reason why concrete can gradually harden and increase its strength is the result of cement hydration, and cement hydration requires certain temperature and humidity conditions. The conventional curing method is to manually pull water pipes to pour on the concrete surface, but when the concrete surface is large, the workers have too much workload and low work efficiency, and it is also easy to produce areas that cannot be cured.
