Description

Technical Field

[0001] The utility model relates to the technical field of concrete, in particular to a curing chamber for concrete specimens. Background Technique

[0002] Ordinary concrete refers to artificial stone made with cement as the main binder, combined with water, sand, gravel, and, if necessary, chemical admixtures and mineral admixtures, proportioned appropriately, and uniformly stirred, densely formed, and cured and hardened. Concrete is mainly divided into two stages and states: the plastic state before setting and hardening, namely fresh concrete or concrete mixture; the hard state after hardening, namely hardened concrete or concrete. The concrete strength grade is divided according to the standard value of the cube compressive strength of concrete. The cube compressive strength of concrete is the cube specimen with a standard size of 150 mm side length made by the standard method. In the standard curing chamber with a temperature of 20 ± 2 °C and a humidity of more than 95%, it is cured to the age of 28 days, and the cube compressive strength of concrete measured by the standard test method. The common strength grades of ordinary concrete in China are divided into: C15, C20, C25, C30, C35, C40, C45, C50, C55, C60, etc.

[0003] After the concrete is poured and vibrated, it can gradually set and harden mainly because of the hydration of cement, and the hydration requires appropriate temperature and humidity conditions. Therefore, in order to ensure that the concrete has suitable hardening conditions and its strength continues to increase, the concrete must be cured. In the existing patent (CN202220628837.0), the concrete specimens need to be cured in a certain humidity environment for subsequent performance testing. During curing, the internal environment is dim, and it is easy for people to bump into things when entering and leaving. Therefore, a curing chamber for concrete specimens is provided.
