相比传统的石膏材料而言，grc作为一种新型的轻型材料在制造和安装环节得到了大幅度的技术提升。但是即使如此，在grc构件施工期间有性以及要点还是不能够被忽视的。

Compared with traditional gypsum materials, GRC, as a new light-weight material, has been greatly improved in manufacturing and installation. But even so, the safety and key points during GRC component construction cannot be ignored.

grc构件施工期间性

Safety during GRC component construction

人生：由于grc构件安装位置处于室外属于高空作业，需安装固定的脚手架和其它保护措施，如未进行保护措施易造成高空坠亡。

Life safety: since GRC components are installed outdoors and belong to high-altitude operation, fixed scaffolds and other protective measures need to be installed. If protective measures are not taken, it is easy to fall from high altitude.

构件质量：GRC构件是一种以耐碱玻璃纤维为增强材料、水泥砂浆为基体材料的纤维混凝土复合材料，GRC构件的体积密度约为1.8-1.9,8mm厚标准GRC板重量仅为15kg，抗压强度超过40Mpa，抗弯强度超过34Mpa，大大超过国际标准要求。

Component quality: GRC component is a kind of fiber concrete composite material with alkali resistant glass fiber as reinforcement and cement mortar as matrix material. The volume density of GRC component is about 1.8-1.9, and the weight of 8mm thick standard GRC plate is only 15kg. The compressive strength exceeds 40MPa and the flexural strength exceeds 34mpa, which greatly exceeds the requirements of international standards.

构件安装性：固定件总是位于潮湿环境，大多数铁合金在这种条件下都会腐蚀，这不仅在建筑材料上形成难看的锈斑，而且对结构造成损害。锈蚀的低碳钢将会分层并膨胀超过原始厚度的4倍，这种膨胀对GRC板有明显损害。

Safety of component installation: the fixed parts are always located in a humid environment, and most ferroalloys will corrode under this condition, which will not only form ugly rust spots on the building materials, but also cause damage to the structure. The corroded mild steel will be stratified and expanded more than 4 times the original thickness, which will obviously damage the GRC Plate.

grc构件施工期间关注要点

Key points for attention during GRC component construction

1、水泥基外墙保温grc构件应使用抗裂砂浆。此外，重量比应控制在干粉：4和水：5的比例，以便完全搅拌以达到均匀，这个用起来很简单。

1. Anti crack mortar shall be used for GRC components of cement-based exterior wall insulation. In addition, the weight ratio should be controlled at the ratio of dry powder: 4 and water: 5, so that it can be completely stirred to achieve uniformity, which is very simple to use.

2、济南GRC构件的结构宽度在1.10m1.20m范围内，将搅拌好的保护砂浆自下而上均匀地铺在grc装饰构件上，保持在板面的保护砂浆的平均厚度小于3毫米。

2. The structural width of Jinan GRC members is within the range of 1.10M to 1.20m. The mixed protective mortar is evenly laid on GRC decorative members from bottom to top, and the average thickness of the protective mortar on the plate surface is kept less than 3mm.

3、在防护砂浆仍有良好和易性的时间范围内，及时将玻璃纤维网布推入防护砂浆中，使网格挤出的防护砂浆平整。玻璃纤维网布应完全包裹在保护砂浆中，一方面玻纤网布应尽量贴近防护砂浆表面。另一方面玻璃纤维网布不应暴露在保护面层的表面。

3. Within the time range when the protective mortar still has good workability, push the glass fiber mesh into the protective mortar in time to make the protective mortar extruded by the grid smooth. The glass fiber mesh should be completely wrapped in the protective mortar. On the one hand, the glass fiber mesh should be as close to the surface of the protective mortar as possible. On the other hand, the glass fiber mesh should not be exposed to the surface of the protective surface.
