Description

Technical Field

[0001] The utility model relates to the technical field related to cement mortar curing boxes, in particular to an anti-caking cement mortar curing box. Background Art

[0002] In construction projects, accurate assessment of the strength of concrete and cement mortar can provide a reliable basis for construction projects. The curing conditions of concrete and mortar have a direct relationship with the test strength. Different curing conditions for curing concrete mortar will result in greater dispersion of the test strength and poorer accuracy. The main method of curing cement mortar is to keep the temperature five degrees higher than the natural condition, cover the mortar to a certain extent, and use watering, windproofing, heat preservation and other curing measures to maintain the cement mortar.

[0003] Chinese patent publication number (CN219213610U) discloses an anti-caking cement mortar curing box. The anti-caking cement mortar curing box facilitates the stirring of cement mortar through the design of a stirring motor, thereby preventing the cement mortar from settling and solidifying due to long-term storage. At the same time, the heating area of ​​the cement mortar is increased during the stirring process, thereby improving the curing effect of the cement mortar and improving the practicality and automation of the curing box body. However, the shortcoming is that in this technical solution, when the stirring motor drives the stirring blades to stir the cement mortar, it simply uses a central stirring method for stirring, and the stirring is relatively insufficient. Some cement mortars are easily deposited on the inner wall and bottom of the curing box under the action of centrifugal force and gravity, and agglomerate. The anti-caking effect is poor, which affects the curing effect of the cement mortar. Utility Model Content
