GRC是一種廣泛使用的纖維水泥復合材料。與混凝土具有相同的性能和壽命，是一種可回收利用的綠色建筑材料，一般用于這些建筑中裝飾房屋和建筑。看看
山東GRC構件的特點和施工步驟的內容。
GRC is a widely used fiber cement composite. With the same performance and life as concrete, it is a recyclable green building material, which is generally used to decorate houses and buildings in these buildings. Look at the characteristics of Shandong GRC components and the contents of construction steps.
GRC組件的特性
Characteristics of GRC components
耐透濕性：如果耐透濕性差，GRC構件中的建筑鋼筋容易被腐蝕，威脅構件的壽命。影響抗滲性的主要因素是混凝土類型、碎石粒徑和配合比、混凝土水灰比和GRC構件密度。
Moisture resistance: if the moisture resistance is poor, the building reinforcement in GRC components is easy to be corroded, threatening the service life of the components. The main factors affecting the impermeability are the type of concrete, the size and mix ratio of crushed stone, the water-cement ratio of concrete and the density of GRC components.
耐寒性：在水飽和條件下，GRC模塊可以減少凍結中的凍害。這是因為GRC構件中存在許多相同或不相連的空隙，這些空隙成為水蒸氣的通道和儲水的，當GRC構件飽和時會凍結。內部水分凍結，體積被吸收8%，孔隙膨脹，產生拉伸應力。通過融化。當拉應力超過GRC構件抗壓強度時，凍結體系逐漸誘導微裂紋擴展，并相互連接，會破裂
Cold resistance: under water saturation conditions, GRC module can reduce freezing damage during freezing. This is because there are many identical or unconnected voids in GRC members, which become the channel of water vapor and the center of water storage, and will freeze when GRC members are saturated. The internal water freezes, the volume is absorbed by 8%, and the pore expands, resulting in tensile stress. By melting. When the tensile stress exceeds the compressive strength of GRC members, the freezing system will gradually induce microcracks to expand and connect with each other, which will break
耐腐蝕性：有機鹽、堿骨料等的侵蝕和碳化等產品的侵蝕，會降低GRC構件的抗壓強度，破壞GRC構件的結構體積，影響壽命。
Corrosion resistance: the erosion of organic salts, alkali aggregates, and carbonation products will reduce the compressive strength of GRC members, destroy the structural volume of GRC members, and affect the service life.
GRC構件的施工順序
Construction sequence of GRC components
1.根據施工圖的不同，GRC構件的安裝位置會出現定位線。
1. According to the different construction drawings, the location line will appear at the installation position of GRC components.
2.粘貼GRC構件時，請將網眼布翻過來。特殊情況下，可以不翻轉就粘貼。用薄層全粘法粘貼擠出GRC構件，使砂漿四周溢出，膠縫寬度不大于3mm。膠縫應粘結在吊鉤上，灰縫應飽滿，GRC構件表面應保持清潔。
2. When pasting GRC components, please turn the mesh over. In special cases, you can paste without flipping. Paste and extrude GRC components with thin layer full adhesive method, so that the mortar overflows around, and the width of adhesive joint is not more than 3mm. The glue joint shall be bonded on the hook, the mortar joint shall be full, and the GRC component surface shall be kept clean.
3.對于大型GRC零件，安裝時有要求，需要臨時固定金屬件。
3. For large GRC parts, it is required to temporarily fix metal parts during installation.
4.安裝時需拼接時，應提前測量拼接尺寸和角度，提前在平整處進行拼接，間隙小于3mm。作為粘結砂漿的拼接粘結材料，砂漿稠度可以較大，采用薄層全粘結方式。拼接時，用鐵錘輕輕均勻按壓，使灰縫符合要求。
4. When splicing is required during installation, the splicing size and angle shall be measured in advance, and the splicing shall be conducted at the flat place in advance, with the gap less than 3mm. As the splicing and bonding material of bonding mortar, the mortar consistency can be large, and the thin layer full bonding method is adopted. When splicing, press gently and evenly with a hammer to make the mortar joint meet the requirements.
5.灰縫后，用砂漿刀壓平，使GRC構件一體化。干燥后，如果GRC構件接縫處有多余的粘結砂漿，可以用砂紙打磨。干燥后，用GRC構件拼接部分專用防裂膠處理。請參照專用防裂橡膠的使用說明進行處理。
5. After mortar joint, use mortar knife to flatten to integrate GRC components. After drying, if there is excess bonding mortar at the joints of GRC members, it can be sanded. After drying, use special anti-crack adhesive for GRC component splicing. Please refer to the instructions of special anti-crack rubber for treatment.
After the GRC components are assembled, pay attention to the protection of finished products, and do not step on or collide with heavy objects. If damaged, the entire components of the electric steering system must be removed and reinstalled. Come to our website for more relevant content http://m.libpo.com.cn Consult and understand!
