Description

Technical Field

[0002] Mass concrete occupies a vital position in modern construction projects. With the continuous advancement of infrastructure construction, mass concrete is widely used in important engineering structures such as large bridges, dams, foundations of high-rise buildings, and foundations of large industrial equipment. It has the characteristics of large structural size, large amount of concrete, and complex engineering conditions. For example, in the pier foundation of a large bridge, mass concrete can provide strong bearing capacity and stability to ensure the safe operation of the bridge under various loads; in dam projects, the mass concrete dam body can withstand huge water pressure and ensure the normal function of water conservancy facilities. Natural curing cannot effectively control the internal temperature of concrete. Mass concrete will generate a lot of heat during the hydration process. If it cannot be dissipated in time, it will cause the internal temperature of the concrete to be too high, forming a large temperature difference with the surface, and then causing temperature cracks. Therefore, curing equipment will be used to maintain mass concrete.
