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原材料拼裝進行后，對接口處開展，將硫鋁酸鹽水泥、建筑膠、丙烯酸乳液、抗堿底漆化學纖維按1:0.2:0.05:0.02(凈重比)混和成濃稠化合物。應將連接頭修補并卡緊到2mm處的GRC表層。72鐘頭后，連接頭上的塵土，隨后引入環氧膠泥密封膠并開展刮擦。

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原材料構成

GRC raw material composition

GRC的基本特征是混凝土、碎石子、化學纖維和水，除此之外也有高聚物、防腐劑和別的用以改進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混凝土中關鍵有硬實硫鋁酸鹽水泥、低酸堿度硫鋁酸鹽水泥、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.

化學纖維:用以GRC構件原材料的化學纖維一定是耐堿性玻纖，包含耐堿性玻纖粗紗、耐堿性玻纖短纖紗、耐堿性玻璃纖維網布。歐洲規定玻纖中應用的氧化鋯含水量在GRC中不可小于百分之16.5，規定一般粉煤灰水泥中應用的氧化鋯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，或丙烯酸樹脂預聚物保濕乳液。

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

減水劑:一般可選擇性地加上合理外加劑、增粘劑、緩凝劑、早強劑、混凝土防凍劑、防銹油等減水劑:當商品中帶有建筑鋼筋原材料或鋼埋件時，不可應用氯化鈣基減水劑。

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.

別的原材料:可選擇性添加一部分熱裂解特異性原材料，提升GRC商品的抗壓強度、抗滲等級性、使用性能等綜合型能。

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原材料預制構件的平時維護保養:

Daily maintenance of GRC raw material prefabricated components:

1、盡量減少塵土和污垢，假如表層有塵土或廢棄物，能夠 用吸塵機來清理，并保證吸塵機是軟毛刷，由于硬刷將會會刮傷板巖。

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,安裝后應盡早蓋公章:海象能夠 做為保護層厚度,能夠 是一個好方法避免塵土和污垢的內容和板巖中的水揮發,不然,當它與氣體中的化學物質產生反映會導致危害。

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、不必觸碰原料油:由于原料油或廢棄物會造成砂巖背景墻臟污，假如觸碰應盡可能清理。

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、防止應用瓷磚清潔劑開展清理，由于它會使地磚退色，運用整潔的薄布和溫開水，常常開展擦洗能夠 避免危害化合物的堆積，并危害表層。GRC原材料工程施工鋪貼方式:GRC原材料工程施工鋪貼可選用“裂開”和“暗縫”方式。說白了“亮縫”，就是指GRC原材料依照施工圖設計規定和一定的工程建筑應變速率開展組裝，在接縫處口預埋12~20mm的接縫處，做到的裝飾設計實際效果。“暗縫”方式修補GRC原材料的接縫處，做到總體實際效果!

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!
