随着建造技术和材料行业的发展，越来越多非线性的，具有流线感的设计，得以脱离纸面，落地成型。其中
济南GRC构件的应用已经屡见不鲜。于GRC构件的原材料是什么很多人都还不是很清楚，由于GRC构件属于新型建筑装饰材料，其安装方法也少有人知，下面小编为大家一一讲解。
With the development of construction technology and material industry, more and more non-linear and streamlined designs can be separated from the paper and formed on the ground. Among them, the application of Jinan GRC component has been common. As for the raw materials of GRC components, many people are not very clear. As GRC components are new building decoration materials, few people know their installation methods. The following small series will explain them one by one.
GRC构件的原材料
Raw materials of GRC components
1.耐碱玻璃纤维无捻粗纱：氧化锆含量在14.5—16.5%，耐碱玻璃纤维短切纱，耐碱玻璃纤维网格布。
1. Alkali resistant glass fiber untwisted roving: zirconia content is 14.5-16.5%, alkali resistant glass fiber chopped yarn, alkali resistant glass fiber mesh cloth.
2.不低于42.5级的硫铝盐酸低碱水泥，不低于42.5级的普通硅酸盐水泥，不低于42.5级的普通硅酸盐白水泥。
2. Sulfur aluminum hydrochloric acid low alkali cement not lower than grade 42.5, ordinary portland cement not lower than grade 42.5 and ordinary Portland white cement not lower than grade 42.5.
3.硅砂，又名二氧化硅，或石英砂。硅含量应占总量的95%以上，氯化物含量小于0.01%，含泥量不得大于1%。
3. Silica sand, also known as silica or quartz sand. The silicon content shall account for more than 95% of the total amount, the chloride content shall be less than 0.01%, and the mud content shall not be more than 1%.
4.外加剂：缓凝减水剂，抗老化剂，早强剂，防冻剂，除锈剂等。当构建中含有钢制增强材料或者钢制预埋件时，不得使用氧化钙基的外加剂。
4. Admixtures: high efficiency retarding and water reducing agent, anti-aging agent, early strength agent, antifreeze agent, rust remover, etc. When the construction contains steel reinforcement materials or steel embedded parts, calcium oxide based admixtures shall not be used.
5.钢筋。采用热轧低碳钢或不锈钢，为有效阻止钢筋生锈，宜采用镀锌钢丝，直径宜采用4-6mm，直径允许偏差±0.07，锌层重量不小于290g/㎡。
5. Reinforcement. Hot rolled low-carbon steel or stainless steel shall be used. In order to effectively prevent the rebar from rusting, galvanized steel wire shall be used. The diameter shall be 4-6mm, the allowable deviation of diameter shall be ± 0.07, and the weight of zinc layer shall not be less than 290g / ㎡.
GRC构件安装方法
GRC component installation method
根据施工图纸，在待安装GRC构件的部位弹出定位线。粘贴时，网格布应当翻包，如有特殊情况可直接粘贴不翻包。采用薄层满粘法进行粘贴，用力挤压构件使砂浆从周边溢出，粘接缝宽不大于3mm。粘结缝应随粘随勾，灰缝饱满，并保持构件表面的整洁。
According to the construction drawings, snap the positioning line at the position where GRC components are to be installed. When pasting, the mesh cloth should be turned over. In case of special circumstances, it can be directly pasted without turning over. The thin layer full adhesion method shall be adopted for bonding, and the mortar shall be forced to overflow from the periphery by squeezing the component. The width of the bonding joint shall not be greater than 3mm. The bonding joint shall be hooked with the bonding, the mortar joint shall be full, and the surface of the component shall be kept clean.
安装时，若需拼接，应事先测量好拼装尺寸和角度，并在平整地方进行预拼装，缝隙不大于3mm。粘结砂浆作拼接粘结材料，砂浆稠度可销大些，采用薄层满粘法进行。拼接时要求稍微、均匀用力挤压锤打，以使灰缝满足要求。
During installation, if splicing is required, the assembly size and angle shall be measured in advance, and the pre assembly shall be carried out at a flat place with a gap of no more than 3mm. The bonding mortar is used as the bonding material for splicing. The consistency of the mortar can be increased. The thin layer full bonding method is adopted. During splicing, it is required to squeeze and hammer slightly and evenly to make the mortar joint meet the requirements.
