A device and method for indoor test and maintenance of building cement

Abstract

The invention discloses a building cement indoor testing and maintaining device and method. The building cement indoor testing and maintaining device comprises a table body. The table body is providedwith an electric control assembly, a lifting mechanism, a water feed assembly, a stirring mechanism and a maintaining assembly. The electric control assembly comprises an electric control box and a control panel. The lifting mechanism comprises lifting air cylinders, air cylinder push rods and a beam. The water feed assembly comprises water tanks, water feed pumps and water feed sprayers. The stirring mechanism comprises a motor, a coupler, a stirring shaft and stirring blades. The maintaining assembly comprises a shell, a maintaining box, a constant-temperature electric heating pipe and an air blower. The electric control assembly is used for controlling running of the whole device, traditional manual cement maintaining is avoided, manpower is saved, and manpower damage is reduced. In addition, various mechanisms independently work, the arrangement between the mechanisms is reasonable in the whole operation process, the structure is simple, work division is clear, and regulation andcontrol performance is high. In addition, the constant-temperature electric heating pipe and the air blower are arranged in the maintaining assembly, the cement solidification time is shortened, and the cement detecting and testing efficiency and qualification rate are increased.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an indoor test and maintenance device and method for building cement. Background technique [0002] Cement plays an indispensable role in the field of construction. The quality indicators of cement products, including stability, setting time, strength at various ages, shrinkage, etc., need to be aged at a specific temperature and humidity for different days. Curing, the temperature of the curing specimen has a close relationship with the hydration, coagulation, and hardening of the cement. Experiments have proved that for every 1°C difference in the curing water humidity, the cement strength index will differ by 1-2%. Therefore, control and maintain a constant curing Temperature and humidity are of special significance to test the performance of cement and reflect the quality of cement. [0003] The national standard stipulates that the maintenance standard of cement ...

AI Technical Summary

Problems solved by technology

[0003] The national standard stipulates that the maintenance standard of cement products is: the temperature is about 20°C, and the relative humidity is not lower than 90%. At present, the commonly used maintenance methods and equipment are air conditioner heat preservation and spray heat preservation. The disadvantage is that it consumes a lot of cost. A specific maintenance space is required, once the air conditioner is damaged, the entire maintenance equipment will be paralyzed

Secondly, the existing cement is naturally air-dried during the curing process, and the curing time is long, and the cement is prepared manually during the curing process, which consumes labor, the curing efficiency is low, and the qualified rate of the final cement product is not high.
