山東GRC構件的主要特點是壁薄體輕、造型隨意、質感逼真、減排。其GRC玻璃纖維含量與其力學性能特別是抗彎強度之間的對應關系應通過實驗確定。下面從這兩個方面來了解下該構件吧。
The main features of Shandong GRC components are thin wall, light body, random shape, realistic texture, energy saving and emission reduction. The corresponding relationship between GRC glass fiber content and its mechanical properties, especially bending strength, shall be determined through experiments. Let's learn about this component from these two aspects.
山東GRC構件的主要特點
Main features of GRC components in Shandong
1、薄體輕。GRC密度在2000/m3左右，比混凝土輕一些，但它可以做成薄壁型構件。一般情況下，GRC構件壁厚在15mm左右，厚的構件壁厚不到30mm,,薄的構件壁厚5mm。
1. Thin and light. GRC density is about 2000/m3, which is lighter than concrete, but it can be made into thin-walled members. Generally, the wall thickness of GRC members is about 15mm, that of thick members is less than 30mm, and that of thin members is 5mm.
2、隨意。GRC構件是在模具中制作成型的。由于重量輕，實現造型很方便，GRC可以做成各種復雜的造型。
2. At will. GRC components are made and formed in the mold. Due to its light weight, GRC can be made into various complex shapes.
3、感逼真。GRC表面質感是由模具質感所決定的。由于GRC中沒有粗集料，所用細集料的顆粒也比較細。因此，可以細膩、準確地表現不同的質感與紋理。既可以做得光滑如鏡也可以做得粗糙似石。復制的各種質感效果非常逼真，是非常理想的仿真材料。
3. Realistic. GRC surface texture is determined by mold texture. Since there is no coarse aggregate in GRC, the fine aggregate used is also fine. Therefore, it can express different textures and textures delicately and accurately. It can be made as smooth as a mirror or as rough as a stone. The various texture effects copied are very realistic and are very ideal simulation materials.
4、減排。山東GRC構件與其他墻體圍護結構比較，其制造和安裝過程消耗能源要少，有學者曾經做過GRC墻板與鋼筋混凝土墻板的碳排放量比較，使用GRC墻板可以降低30%的碳排放量。
4. Emission reduction. Compared with other wall envelope structures, the manufacturing and installation of GRC components in Shandong consumes less energy. Some scholars have compared the carbon emissions of GRC wallboard and reinforced concrete wallboard, and the use of GRC wallboard can reduce the carbon emissions by 30%.
山東GRC構件的玻璃纖維含量與其力學性能特別是抗彎強度之間的對應關系應通過實驗確定。
The corresponding relationship between the glass fiber content of GRC components in Shandong and their mechanical properties, especially the bending strength, should be determined through experiments.
玻璃纖維含量范圍:
Glass fiber content range:
噴射法：4%~5%
Spray method: 4%~5%
預混法：3%~3.5%
Premixed method: 3%~3.5%
這里的玻璃纖維含量是玻璃纖維與GRC總質量之比，而不是與水泥重量之比。實際生產時也有以水泥重量為基數確定玻璃纖維含量的，這時須進行換算。對于灰砂比1:1，水灰比0.4的GRC，5%玻璃纖維含量換算為水泥為基數的比例，大約是12%.
The glass fiber content here is the ratio of glass fiber to the total mass of GRC, not the ratio of glass fiber to the weight of cement. In actual production, the glass fiber content is also determined based on the cement weight, and conversion is required at this time. For GRC with cement sand ratio of 1:1 and water cement ratio of 0.4, the ratio of 5% glass fiber content to cement is about 12%
使用玻璃纖維網格布或短切絲氈時，玻璃纖維效率會提高，玻璃纖維含量可以進行當量換算。應根據實驗確定。
When using glass fiber mesh cloth or chopped strand mat, the glass fiber efficiency will be improved, and the glass fiber content can be equivalent converted. It shall be determined by experiment.
