Embodiment 1

[0063] This embodiment provides a steam curing method for a partition wall, which includes the following steps:

[0064] Bind every 5 partition boards into a bundle, and every 2 bundles corresponds to a curing layer and stack them in the curing room. During the curing process, the oil heating pipeline in the curing room is used for temperature control, and the steam pipeline in the curing room is used to enter Steam, steam temperature is 110°C, pressure is 8kg / cm 2 . The temperature control in the curing process includes a heating stage, a second heating stage, a third heating stage and a cooling stage.

[0065] Among them, the relative humidity is kept at about 90% in the first heating stage, the second heating stage and the third heating stage, and it is carried out under airtight conditions; in the first heating stage, the temperature in the curing room is raised to 23 ° C and kept for 2 hours; In the second heating stage, the temperature in the curing room was raised to ...

Abstract

The invention discloses a partition wall plate steam curing method and a steam curing method for concrete products, and relates to the technical field of concrete curing. According to the partition wall plate steam curing method, to-be-cured partition wall plates are bundled and then placed in a curing chamber, temperature control is conducted through an oil delivery pipeline for heating in the curing process, steam is introduced through a steam pipeline for humidity control, the temperature and humidity can be precisely controlled, meanwhile, adjusting and controlling of the humidity are notaffected by controlling over the humidity, and thus operation flexibility is high; and temperature control in the curing process is divided into three times of temperature increasing, the great curingeffect is obtained, finally, it is ensured that the water content on the surface of a component after natural temperature decreasing reaches the specified requirement, repeated detecting is avoided,and the time and labor are saved. The steam curing method for the concrete products comprises the partition wall plate steam curing method, the flexibility of temperature and humidity control can be significantly improved, and the temperature control precision is high.

Description

technical field [0001] The invention relates to the technical field of concrete curing, and in particular to a steam curing method for a partition board and a steam curing method for concrete products. Background technique [0002] After the concrete is poured, if the climate is hot and the air is dry, if the maintenance is not carried out in time, the water in the concrete will evaporate too quickly, forming a dehydration phenomenon, which will make the cement particles that have formed a gel body unable to fully hydrate and cannot be transformed into stable crystals. Lack of sufficient cohesion, resulting in flaking or powdering off the concrete surface. In addition, when the concrete does not have sufficient strength, the premature evaporation of water will also cause large shrinkage deformation and dry shrinkage cracks. Therefore, the maintenance of the initial stage after concrete pouring is very important. The concrete should be cured immediately after the final setti...
