GRC是一种广泛使用的纤维水泥复合材料。与混凝土具有相同的性能和寿命，是一种可回收利用的绿色建筑材料，一般用于这些建筑中装饰房屋和建筑。看看
山东GRC构件的特点和施工步骤的内容。
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组件的特性
Characteristics of GRC components
耐透湿性：如果耐透湿性差，GRC构件中的建筑钢筋容易被腐蚀，威胁构件的寿命。影响抗渗性的主要因素是混凝土类型、碎石粒径和配合比、混凝土水灰比和GRC构件密度。
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：在水饱和条件下，GRC模块可以减少冻结中的冻害。这是因为GRC构件中存在许多相同或不相连的空隙，这些空隙成为水蒸气的通道和储水的，当GRC构件饱和时会冻结。内部水分冻结，体积被吸收8%，孔隙膨胀，产生拉伸应力。通过融化。当拉应力超过GRC构件抗压强度时，冻结体系逐渐诱导微裂纹扩展，并相互连接，会破裂
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
耐腐蚀性：有机盐、碱骨料等的侵蚀和碳化等产品的侵蚀，会降低GRC构件的抗压强度，破坏GRC构件的结构体积，影响寿命。
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构件的施工顺序
Construction sequence of GRC components
1.根据施工图的不同，GRC构件的安装位置会出现定位线。
1. According to the different construction drawings, the location line will appear at the installation position of GRC components.
2.粘贴GRC构件时，请将网眼布翻过来。特殊情况下，可以不翻转就粘贴。用薄层全粘法粘贴挤出GRC构件，使砂浆四周溢出，胶缝宽度不大于3mm。胶缝应粘结在吊钩上，灰缝应饱满，GRC构件表面应保持清洁。
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.对于大型GRC零件，安装时有要求，需要临时固定金属件。
3. For large GRC parts, it is required to temporarily fix metal parts during installation.
4.安装时需拼接时，应提前测量拼接尺寸和角度，提前在平整处进行拼接，间隙小于3mm。作为粘结砂浆的拼接粘结材料，砂浆稠度可以较大，采用薄层全粘结方式。拼接时，用铁锤轻轻均匀按压，使灰缝符合要求。
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.灰缝后，用砂浆刀压平，使GRC构件一体化。干燥后，如果GRC构件接缝处有多余的粘结砂浆，可以用砂纸打磨。干燥后，用GRC构件拼接部分专用防裂胶处理。请参照专用防裂橡胶的使用说明进行处理。
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://www.aswjc.com Consult and understand!
