GRC构件是一种新型修建资料，曾经我们还不是很了解这款建材，现在随着grc构件等产品曝光度进步，知名度进步，越来越多人挑选grc产品来装修自己的房子别墅。
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资料组成
GRC data composition
GRC的根本组成资料为水泥、砂子、纤维和水，别的还增加有聚合物、外加剂等用于改善后期功能的资料。
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铝酸盐水泥、低碱度硫铝酸盐水泥、一般硅酸盐水泥、白色硅酸盐水泥。
Cement: the cement commonly used in GRC mainly includes fast hardening sulphoaluminate cement, low alkalinity sulphoaluminate cement, general Portland cement and white portland cement.
纤维：GRC资料中运用的纤维有必要是耐碱玻璃纤维，品种包括耐碱玻璃纤维无捻粗纱、耐碱玻璃纤维短切纱、耐碱玻璃纤维网格布。欧美国--家要求GRC中运用的玻璃纤维氧化锆含量不低于16.5%，国内要求在运用一般硅酸盐水泥时氧化锆含量不低于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：一般增加的聚合物为丙乳，即丙烯酸酯共聚乳液。
Polymer: the generally added polymer is acrylic emulsion, that is, acrylate copolymer emulsion.
外加剂：一般可挑选性地参加减水剂、塑化剂、缓凝剂、早强剂、防冻剂、防锈剂等外加剂:当制品中含有钢质增强资料或钢质预埋件时，不得运用氯化钙基的外加剂。
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.
其他资料：能够挑选性的增加一些火山灰质活性资料，有利于提升GRC制品的归纳功能，例如强度、抗渗、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资料施工拼接缝可采用“明缝”与“暗缝”的处理办法。所谓“明缝”是指GRC资料在组装时，依据图纸规划要求，依照必定的修建模数，在接缝口处预留12~20mm的自然缝口，来到达的装修作用。而“暗缝”处理办法需在GRC资料拼接缝处进行修补处理，使线条到达全体流通一致的装修作用。
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.
施工办法：GRC资料组装完成后，接缝处做清洁处理，用硫铝酸盐水泥、修建胶水、丙稀酸乳液、抗碱纤维丝按1：0.2：0.05：0.02(分量比)调制均匀成粘稠状的混合浆，对接缝处进行修补，修补密实GRC外表2mm处。待72小时后，铲除接缝处尘埃，再用水泥基密封胶注入并刮平。
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.
