GRC構件是一種新型修建資料，曾經(jīng)我們還不是很了解這款建材，現(xiàn)在隨著grc構件等產(chǎn)品曝光度進步，知名度進步，越來越多人挑選grc產(chǎn)品來裝修自己的房子別墅。
GRC components are a new type of construction materials. We didn't know much about this building material before. Now, with the improvement of the exposure and popularity of GRC components and other products, more and more people choose GRC products to decorate their houses and villas.
GRC資料組成
GRC data composition
GRC的根本組成資料為水泥、砂子、纖維和水，別的還增加有聚合物、外加劑等用于改善后期功能的資料。
The basic composition data of GRC are cement, sand, fiber and water. In addition, polymers, admixtures and other data used to improve later functions are added.
水泥：一般用于GRC中的水泥主要有快硬硫鋁酸鹽水泥、低堿度硫鋁酸鹽水泥、一般硅酸鹽水泥、白色硅酸鹽水泥。
Cement: the cement commonly used in GRC mainly includes fast hardening sulphoaluminate cement, low alkalinity sulphoaluminate cement, general Portland cement and white portland cement.
纖維：GRC資料中運用的纖維有必要是耐堿玻璃纖維，品種包括耐堿玻璃纖維無捻粗紗、耐堿玻璃纖維短切紗、耐堿玻璃纖維網(wǎng)格布。歐美國--家要求GRC中運用的玻璃纖維氧化鋯含量不低于16.5%，國內(nèi)要求在運用一般硅酸鹽水泥時氧化鋯含量不低于16.5%。
Fiber: the fiber used in GRC data must be alkali resistant glass fiber, including alkali resistant glass fiber untwisted roving, alkali resistant glass fiber chopped yarn and alkali resistant glass fiber grid cloth. European and American countries require that the content of glass fiber zirconia used in GRC shall not be less than 16.5%, and domestic requirements that the content of zirconia used in general Portland cement shall not be less than 16.5%.
聚合物：一般增加的聚合物為丙乳，即丙烯酸酯共聚乳液。
Polymer: the generally added polymer is acrylic emulsion, that is, acrylate copolymer emulsion.
外加劑：一般可挑選性地參加減水劑、塑化劑、緩凝劑、早強劑、防凍劑、防銹劑等外加劑:當制品中含有鋼質增強資料或鋼質預埋件時，不得運用氯化鈣基的外加劑。
Admixtures: generally, high-efficiency water reducer, plasticizer, retarder, early strength agent, antifreeze, antirust agent and other admixtures can be selected: calcium chloride based admixtures shall not be used when the products contain steel reinforcement materials or steel embedded parts.
其他資料：能夠挑選性的增加一些火山灰質活性資料，有利于提升GRC制品的歸納功能，例如強度、抗?jié)B、耐久等。
Other data: some pozzolanic activity data can be selectively added, which is conducive to improving the inductive function of GRC products, such as strength, impermeability, durability, etc.
GRC資料施工拼接縫可采用“明縫”與“暗縫”的處理辦法。所謂“明縫”是指GRC資料在組裝時，依據(jù)圖紙規(guī)劃要求，依照必定的修建模數(shù)，在接縫口處預留12~20mm的自然縫口，來到達的裝修作用。而“暗縫”處理辦法需在GRC資料拼接縫處進行修補處理，使線條到達全體流通一致的裝修作用。
The construction joint of GRC data can be treated by "open joint" and "concealed joint". The so-called "open joint" refers to that during the assembly of GRC data, 12 ~ 20mm natural joint is reserved at the joint opening according to the drawing planning requirements and certain construction modulus to achieve the decoration function. The "concealed joint" treatment method needs to be repaired at the splicing joint of GRC data to make the lines reach the decoration function of consistent circulation.
施工辦法：GRC資料組裝完成后，接縫處做清潔處理，用硫鋁酸鹽水泥、修建膠水、丙稀酸乳液、抗堿纖維絲按1：0.2：0.05：0.02(分量比)調制均勻成粘稠狀的混合漿，對接縫處進行修補，修補密實GRC外表2mm處。待72小時后，鏟除接縫處塵埃，再用水泥基密封膠注入并刮平。
Construction method: after the assembly of GRC data is completed, the joints are cleaned. The sulphoaluminate cement, building glue, acrylic acid emulsion, alkali resistant fiber yarn are mixed into a thick paste mixture according to the 1:0.2:0.05:0.02 (component ratio), and the joints are repaired and repaired to GRC 2mm. After 72 hours, remove the dust at the joint, and then inject and scrape with cement-based sealant.
