Description

Concrete curing management device {CONCRETE CURING MANAGEMENT DEVICE}

The present invention relates to a concrete curing management device that enables efficient execution of curing management of poured concrete in building or construction work.

In general, a mixture of cement and sand is called mortar, and a mixture of cement and aggregate such as gravel is called concrete. In particular, reinforcing the tension of a structure by inserting reinforcing bars into concrete is called reinforced concrete. Reinforced concrete is widely used in the construction of buildings and bridges because it provides very high mechanical strength by combining the tensile force of reinforcing bars and the compressive force of concrete.

In the construction of reinforced concrete, the reinforcement is usually laid in a net shape, concrete is poured thereafter, and then the concrete is cured. When water is added to the cement and mixed, the lime component of the cement reacts with the water and generates heat. And, accompanying this exothermic reaction, the cement paste gradually solidifies and hardens. Concrete curing refers to all activities that manage concrete so that it hardens well. Concrete curing includes the act of preventing external physical impact from being applied to uncured concrete, as well as the act of properly maintaining the moisture and temperature of the concrete. In particular, at the beginning of concrete curing, when the moisture in the concrete becomes insufficient or the temperature is constant. For example, if the temperature is lowered below about 4° C., the hardening of the cement is insufficient and the development of strength of the concrete is very low.
