隨著建造技術和材料行業的發展，越來越多非線性的，具有流線感的設計，得以脫離紙面，落地成型。其中
濟南GRC構件的應用已經屢見不鮮。于GRC構件的原材料是什么很多人都還不是很清楚，由于GRC構件屬于新型建筑裝飾材料，其安裝方法也少有人知，下面小編為大家一一講解。
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構件的原材料
Raw materials of GRC components
1.耐堿玻璃纖維無捻粗紗：氧化鋯含量在14.5—16.5%，耐堿玻璃纖維短切紗，耐堿玻璃纖維網格布。
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級的硫鋁鹽酸低堿水泥，不低于42.5級的普通硅酸鹽水泥，不低于42.5級的普通硅酸鹽白水泥。
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。硅含量應占總量的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.外加劑：緩凝減水劑，抗老化劑，早強劑，防凍劑，除銹劑等。當構建中含有鋼制增強材料或者鋼制預埋件時，不得使用氧化鈣基的外加劑。
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.鋼筋。采用熱軋低碳鋼或不銹鋼，為有效阻止鋼筋生銹，宜采用鍍鋅鋼絲，直徑宜采用4-6mm，直徑允許偏差±0.07，鋅層重量不小于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構件安裝方法
GRC component installation method
根據施工圖紙，在待安裝GRC構件的部位彈出定位線。粘貼時，網格布應當翻包，如有特殊情況可直接粘貼不翻包。采用薄層滿粘法進行粘貼，用力擠壓構件使砂漿從周邊溢出，粘接縫寬不大于3mm。粘結縫應隨粘隨勾，灰縫飽滿，并保持構件表面的整潔。
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.
安裝時，若需拼接，應事先測量好拼裝尺寸和角度，并在平整地方進行預拼裝，縫隙不大于3mm。粘結砂漿作拼接粘結材料，砂漿稠度可銷大些，采用薄層滿粘法進行。拼接時要求稍微、均勻用力擠壓錘打，以使灰縫滿足要求。
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.
