The construction of GRC components must be familiar to many people, mainly including "bright joint" and "hidden joint". Bright seam refers to GRC materials assembled according to the drawing design requirements and a certain building modulus, and 12 ~ 20 mm natural seam is reserved at the seam to achieve the decorative effect“ The "hidden seam" treatment method needs to repair the joints of GRC materials to achieve the overall smooth and unified decorative effect.

工程施工方式:GRC原材料拼装进行后，对接口处开展，将硫铝酸盐水泥、建筑胶、丙烯酸乳液、抗碱底漆化学纤维按1:0.2:0.05:0.02(净重比)混和成浓稠化合物。应将连接头修补并卡紧到2mm处的GRC表层。72钟头后，连接头上的尘土，随后引入环氧胶泥密封胶并开展刮擦。

Construction method: after the GRC raw material is assembled, the interface is removed, and the sulphoaluminate cement, building glue, acrylic emulsion and alkali resistant primer chemical fiber are mixed into a thick compound according to the 1:0.2:0.05:0.02 (net weight ratio). The connector shall be repaired and clamped to the GRC surface at 2mm. After 72 hours, remove the dust on the connector, then introduce Epoxy Mastic sealant and carry out scratching.

GRC原材料构成

GRC raw material composition

GRC的基本特征是混凝土、碎石子、化学纤维和水，除此之外也有高聚物、防腐剂和别的用以改进中后期特性的原材料。

The basic characteristics of GRC are concrete, crushed stone, chemical fiber and water. In addition, there are also polymers, preservatives and other raw materials used to improve the characteristics of the middle and later stage.

混凝土:一般用以GRC混凝土中关键有硬实硫铝酸盐水泥、低酸碱度硫铝酸盐水泥、一般粉煤灰水泥、白粉煤灰水泥。

Concrete: generally used in GRC concrete, the key are hard sulphoaluminate cement, low pH sulphoaluminate cement, general fly ash cement and white fly ash cement.

化学纤维:用以GRC构件原材料的化学纤维一定是耐碱性玻纤，包含耐碱性玻纤粗纱、耐碱性玻纤短纤纱、耐碱性玻璃纤维网布。欧洲规定玻纤中应用的氧化锆含水量在GRC中不可小于百分之16.5，规定一般粉煤灰水泥中应用的氧化锆含水量不可小于百分之16.5。

Chemical fiber: the chemical fiber used as raw material of GRC components must be alkali resistant glass fiber, including alkali resistant glass fiber roving, alkali resistant glass fiber staple yarn and alkali resistant glass fiber mesh. European countries stipulate that the moisture content of zirconia used in glass fiber should not be less than 16.5% in GRC, while China stipulates that the moisture content of zirconia used in general fly ash cement should not be less than 16.5%.
              

高聚物:一般添加的高聚物是丙乳，或丙烯酸树脂预聚物保湿乳液。

Polymers: generally added polymers are acrylic latex or acrylic resin prepolymer moisturizing lotion.

减水剂:一般可选择性地加上合理外加剂、增粘剂、缓凝剂、早強剂、混凝土防冻剂、防锈油等减水剂:当商品中带有建筑钢筋原材料或钢埋件时，不可应用氯化钙基减水剂。

Superplasticizer: generally, reasonable admixtures, tackifiers, retarders, early strength agents, concrete antifreeze, antirust oil and other superplasticizers can be selectively added. When the commodity contains raw materials of building steel bars or steel embedded parts, calcium chloride based superplasticizer can not be used.

别的原材料:可选择性添加一部分热裂解特异性原材料，提升GRC商品的抗压强度、抗渗等级性、使用性能等综合型能。

Other raw materials: a part of pyrolysis specific raw materials can be selectively added to improve the comprehensive performance of GRC products, such as compressive strength, impermeability grade and service performance.

GRC原材料预制构件的平时维护保养:

Daily maintenance of GRC raw material prefabricated components:

1、尽量减少尘土和污垢，假如表层有尘土或废弃物，能够 用吸尘机来清理，并保证吸尘机是软毛刷，由于硬刷将会会刮伤板岩。

1. Try to reduce the dust and dirt, if there is dust or waste on the surface, you can use a vacuum cleaner to clean it, and ensure that the vacuum cleaner is a soft brush, because the hard brush will scratch the slate.

2,安裝后应尽早盖公章:海象能够 做为保护层厚度,能够 是一个好方法避免尘土和污垢的内容和板岩中的水挥发,不然,当它与气体中的化学物质产生反映会导致危害。

2. Seal the seal as soon as possible after installation: walrus can be used as the thickness of protective layer, which is a good method to avoid dust and dirt content and volatilization of water in slate. Otherwise, when it reacts with chemical substances in gas, it will cause harm.

3、不必触碰原料油:由于原料油或废弃物会造成砂岩背景墙脏污，假如触碰应尽可能清理。

3. No need to touch raw oil: as raw oil or waste will cause dirt on sandstone background wall, if touched, clean it as far as possible.

4、防止应用瓷砖清洁剂开展清理，由于它会使地砖退色，运用整洁的薄布和温开水，常常开展擦洗能够 避免危害化合物的堆积，并危害表层。GRC原材料工程施工铺贴方式:GRC原材料工程施工铺贴可选用“裂开”和“暗缝”方式。说白了“亮缝”，就是指GRC原材料依照施工图设计规定和一定的工程建筑应变速率开展组装，在接缝处口预埋12~20mm的接缝处，做到的装饰设计实际效果。“暗缝”方式修补GRC原材料的接缝处，做到总体实际效果!

4. To prevent the use of ceramic tile cleaning agent to carry out cleaning, because it will make the floor tiles fade, the use of clean cloth and warm water, often carry out scrubbing, can avoid the accumulation of harmful compounds, and harm the surface. GRC raw material engineering construction paving solution: GRC raw material engineering construction paving can choose "crack" and "hidden joint" solution. To put it bluntly, "bright joint" means that GRC raw materials are assembled according to the construction drawing design regulations and a certain engineering construction strain rate, and 12 ~ 20 mm pure natural joint is embedded in the joint to achieve the actual decorative design effect“ Hidden seam "solution to repair GRC raw material joints, to achieve the overall actual effect!
