在使用中要記得對山東GRC構件的鋼筋、預埋件采取防銹措施。下面就來講講防止
山東GRC構件中鋼筋生銹的方法，方便之后的順利使用。
During use, remember to take rust prevention measures for the reinforcement and embedded parts of Shandong GRC members. Now let's talk about the methods to prevent the rebar from rusting in Shandong GRC members, so as to facilitate the smooth use in the future.
GRC構件一般采用快硬硫鋁酸鹽水泥，屬低堿度水泥，根據規范要求，鋼筋應采用不銹鋼絲或鍍鋅鋼絲、預埋件應采用不銹鋼板或鍍鋅鋼板等，有條件的話可使用環氧涂層鋼筋。
Generally, GRC components are made of quick hardening sulphoaluminate cement, which is low alkalinity cement. According to the specification requirements, stainless steel wire or galvanized steel wire shall be used for reinforcement, stainless steel plate or galvanized steel plate shall be used for embedded parts, and epoxy coated reinforcement can be used if conditions permit.
降低GRC構件的氯離子含量。氯離子含量對鋼筋腐蝕有很大影響，過量的氯離子會破壞鋼筋表面的鈍化膜，造成鋼筋銹蝕。對于GRC材料把關，禁止使用海砂，應定期檢測砂子中的氯離子含量，嚴禁用氯離子含量超標的工業廢水混和砂漿。
Reduce the chloride ion content of GRC components. The content of chloride ion has a great influence on the corrosion of reinforcement. Excessive chloride ion will damage the passive film on the surface of reinforcement and cause corrosion of reinforcement. For GRC material control, it is prohibited to use sea sand, and the chloride ion content in the sand should be tested regularly. It is prohibited to mix mortar with industrial wastewater with chloride ion content exceeding the standard.
外加劑丙烯酸酯共聚乳液(丙乳)。丙乳液是一種高分子聚合物水分散體，是一種水泥改性劑，可改善GRC構件的抗裂、防水、防氯離子滲透、耐磨、耐老化等性能。
Admixture Acrylate copolymer emulsion (acrylic emulsion). Acrylic emulsion is a polymer water dispersion and a cement modifier, which can improve the crack resistance, water resistance, chlorine ion penetration resistance, wear resistance, aging resistance and other properties of GRC components.
增強GRC構件的密實度、完整性和保護層厚度。GRC構件的密實性和完整性是指構件是否有裂縫、無蜂窩空洞、缺棱掉角、露筋等現象，促使鋼筋生銹的關鍵因素還在于大氣中的氧滲入鋼筋表面的能力。
Enhance the compactness, integrity and protective layer thickness of GRC components. The compactness and integrity of GRC components refer to whether the components have cracks, no honeycombs and cavities, missing edges and corners, exposed reinforcement and other phenomena. The key factor to promote reinforcement rust is the ability of atmospheric oxygen to penetrate into the reinforcement surface.
如果構件密實、完好、保護層厚度能得到保證，就能有效阻止水和氧氣進入，GRC構件制作時應采用低水灰比，提高構件密實度，制作過程中嚴格控制預埋件的密實度，嚴格控制預埋件密實度，制作過程中嚴格控制預埋件密實度，嚴格控制預埋件密實度，確保構件密實度不高，不脫模，不漏。
If the components are dense, intact and the thickness of the protective layer can be guaranteed, it can effectively prevent water and oxygen from entering. When making GRC components, low water cement ratio should be used to improve the component compactness. During the manufacturing process, the compactness of embedded parts should be strictly controlled, and the compactness of embedded parts should be strictly controlled. During the manufacturing process, the compactness of embedded parts should be strictly controlled, and the compactness of embedded parts should be strictly controlled to ensure that the component compactness is not high, demoulding is not allowed, and leakage is not allowed.
GRC構件外涂隔離層。該方法可以提高構件的防水性和耐久性，隔離腐蝕環境，延緩碳化速度，保護構件，施工時，要構件附著物，然后用水沖洗，充分干燥，在構件表面涂上砂漿或絕緣層，如瀝青漆、環氧樹脂涂料或油漆等。
GRC components are externally coated with isolation layer. This method can improve the waterproof and durability of the component, isolate the corrosive environment, delay the carbonization speed, and protect the component. During construction, first remove the attachment of the component, then rinse with water, fully dry, and apply mortar or insulating layer on the surface of the component, such as asphalt paint, epoxy resin paint or paint.
