GRC构件中的C为快硬硫铝酸盐水泥,属于特性水泥中快硬高强水泥系列中的成分一种,它以无水硫铝酸钙(3Ca.3Al2O3.CaSO4简写为C4A3S)和硅酸二钙为主要成分的熟料加入适量石膏磨细制成的早强水硬性胶凝材料.称为硫铝酸盐快硬水泥.性能为:比表面>380m2/Kg初凝〈25min、终凝〈3h,强度为425、525、625。
GRC欧式构件具有较好的抗拉抗弯性能,可做得很薄。石家庄GRC构件厚度一般在6—15mm之间。每一种构件的厚度要根据石家庄GRC的强度指标、构件的造型与构造和所承受的荷载类型与大小设计。主要特点是壁薄体轻,造型随意,质感逼真,应用领域广泛。
GRC欧式构件在用于充满潮湿的地方时能够防潮,检测结果证明产品的吸水率仅为0.3%,材料无任何气味,放射性核素限量符合GB6566-2001中规定的A类装饰材料的标准。并且石家庄GRC构件可以进行再生利用,属绿色环保材料,经过良好的造型设计,可构成良好的吸声结构,达到隔声、吸音的作用。
GRC构件强度中水泥强度是指水泥胶砂浆硬化试体所能承受外力破坏的能力,用Map(兆帕斯卡)表示,它是水泥重要物理性能之一。水泥强度又分为抗压、抗折、抗拉强度三种,均指水泥胶砂硬化试体承受压缩破坏、弯曲破坏、拉伸破坏时的最大应力。

 
 
C in GRC component is fast hardening sulphoaluminate cement, which belongs to one of the components of fast hardening and high strength cement series in characteristic cement. It is made of anhydrous calcium sulphoaluminate (3Ca.3Al2O3.CaSO4 abbreviated as C4A3S) and clinker with dicalcium silicate as the main ingredient and added appropriate amount of gypsum grinding. It is called sulphoaluminate fast hardening cement. Its properties are as follows: specific surface > 380m2/kg initial setting for 25min, 25min. The final setting time was 3h, and the strength was 425, 525 and 625.
 
GRC European members have good tensile and flexural properties and can be made very thin. The thickness of GRC members in Shijiazhuang is generally between 6 and 15 mm. The thickness of each component should be designed according to the strength index of GRC in Shijiazhuang, the shape and structure of the component and the type and size of the load it bears. The main features are thin wall, light body, random shape, realistic texture and wide application.
 
GRC European components can be moisture-proof when used in damp places. The test results show that the water absorption rate of the product is only 0.3%, the material has no odor, and the radionuclide limit meets the standard of Class A decorative materials stipulated in GB6566-2001. And the GRC component of Shijiazhuang can be recycled, which is a green environmental protection material. After good shape design, it can form a good sound absorption structure to achieve sound insulation and sound absorption.
 
Cement strength in GRC component strength refers to the ability of cement mortar hardened specimens to withstand external force damage. It is one of the important physical properties of cement expressed by Map (Mpaska). Cement strength can be divided into compressive strength, flexural strength and tensile strength. They all refer to the maximum stress of hardened cement mortar specimens under compressive, bending and tensile failure.
