The C in GRC component is fast hardening sulphoaluminate cement, which belongs to one of the components of fast hardening high strength cement series in characteristic cement. It uses the clinker with anhydrous calcium sulphoaluminate (3ca.3al2o3.caso4 abbreviated as C4A3S) and dicalcium silicate as the main components to participate in the early hardening cementation data made of appropriate amount of gypsum by grinding. It is called sulphoaluminate fast hardening cement. The performance is: the initial setting time is less than 25min and the final setting time is more than 380m2 / kg The strength is 425, 525 and 625. The strength of GRC products depends not only on the strength of cement, but also on the external dimension of a single piece and the filler ratio. If it is determined by the configuration of different rib support structures (such as bamboo bars, etc.), the manufacturer will also stop the scientific skeleton configuration according to the building demand. When GRC members talk about strength, they should first talk about cement strength. Cement strength is an important criterion for evaluating cement quality and an important basis for classifying cement grades. Cement strength refers to the ability of cement mortar to accept external force damage. It is one of the important physical properties of cement, which is expressed by map (megapascal). The strength of cement can be divided into three kinds: compressive strength, flexural strength and tensile strength, all of which refer to the large stress of cement mortar when it is subjected to compression damage, bending damage and tensile damage.

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参加适量石膏磨细制成的早强水硬性胶凝资料.称为硫铝酸盐快硬水泥.性能为:比外表>380m2/Kg初凝〈25min、终凝〈3h，强度为425、525、625。GRC制品的强度除取决于水泥强度外，还取决于单件外表尺寸及填料比，配置不同的筋骨支撑构造(如竹筋钢筋等)所决议的，厂家也会依据建筑需求停止科学的骨架配置。装修用的GRC构件应该是glass-fiber reinfored concrete. 既增加型玻璃纤维混凝土,里面的C for concrete, not for cement.
