GRC构件养护过程中应做哪些正确事项

来源:http://www.aswjc.com/ 发布人:admin 发布时间:2022-10-27

GRC构件内所含水分用于水泥水化并因而发展其强度,降低渗透与收缩。由于水化受到温度的影响,为此在GRC构件养护过程中应使周围空气保持适宜的温度。那么除此之外济南GRC构件养护过程中应做哪些正确事项?
The water contained in GRC components is used for cement hydration and thus develops its strength, reducing permeability and shrinkage. As hydration is affected by temperature, the ambient air shall be kept at a suitable temperature during the curing of GRC components. What else should be done during the maintenance of Jinan GRC components?
1、GRC构件一般均是薄壁和低水灰比的,对GRC挂板而言则具有较大的表面积。为此应采用有效的养护制度,有合适的早强以利脱模和搬运;保证设计强度;限制收缩以防开裂。养护可使水泥水化正常进行以增强强度与黏结,程度上减少体积损失、收缩与可能的开裂。控制失去水分,换而言之,即补充水分是养护的基本点,再外加温度的控制。
1. GRC members are generally thin-walled and low water cement ratio, and have a large surface area for GRC cladding. Therefore, an effective curing system should be adopted with appropriate early strength to facilitate demoulding and handling; Ensure the design strength; Shrinkage is limited to prevent cracking. The curing can make the cement hydration go on normally to enhance the strength and bonding, and reduce the volume loss, shrinkage and possible cracking to a certain extent. To control the loss of moisture, in other words, adding moisture is the basic point of curing, and then adding temperature control.
2、脱模前与脱模时在修饰后,通常用洁净而优良的聚乙烯薄膜将模具包住,这是防止GRC中所含水分的蒸发和受到风的影响,同时也有助于保持水化热。在养护的初期应使GRC构件有足够的强度,使之在脱模与搬运时不致受到损伤。在某些地区需要对GRC构件通宵加热,使温度保持在15℃以上。
2. Before and during demoulding, after modification, the mold is usually wrapped with clean and excellent polyethylene film, which prevents the evaporation of water contained in GRC and the impact of wind, and also helps to maintain the heat of hydration. At the initial stage of curing, GRC members shall have sufficient strength to prevent damage during demoulding and handling. In some areas, GRC components need to be heated overnight to keep the temperature above 15 ℃.

3、后养护当GRC构件在存放与使用时,其周围与养护阶段有明显差异时,采取有控制的后养护是必要的。这可以采取一些简单的方法使制件在存放过程中免受阳光的直接照射。在存放阶段GRC构件应达到设计的强度,此阶段的保护在于限制其干缩。在上述养护过程中,GRC构件的强度得以进一步的提高。搬运与存放采取什么方法反映了GRC构件可达到的强度水平。
3. Post curing When GRC components are stored and used, and their surroundings are obviously different from the curing stage, it is necessary to take controlled post curing. This can take some simple methods to protect the parts from direct sunlight during storage. GRC members shall reach the designed strength during storage, and the protection at this stage is to limit their drying shrinkage. During the above curing process, the strength of GRC components can be further improved. The method of handling and storage reflects the strength level that GRC components can reach.
主要养护阶段是使脱模后的GRC构件继续得到保护,免受日光、风与空气低湿度的影响,一般情况下仍用塑料薄膜包住GRC构件以免受到阳光的直接照射。通过喷湿雾也可保持局部的湿度。关注我们http://www.aswjc.com为您了解更多注意事项!
The main curing stage is to protect the GRC components after demoulding from sunlight, wind and low air humidity. Generally, GRC components are still wrapped with plastic film to avoid direct sunlight. Local humidity can also be maintained by spraying wet fog.
