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構件中的C為快硬硫鋁酸鹽水泥，屬于特性水泥中快硬高強水泥系列中的成分一種，它以無水硫鋁酸鈣(3Ca.3Al2O3.CaSO4簡寫為C4A3S)和硅酸二鈣為主要成分的熟料參加適量石膏磨細制成的早強水硬性膠凝資料.稱為硫鋁酸鹽快硬水泥.性能為:比外表>380m2/Kg初凝〈25min、終凝〈3h，強度為425、525、625。GRC制品的強度除取決于水泥強度外，還取決于單件外表尺寸及填料比，配置不同的筋骨支撐構造(如竹筋鋼筋等)所決議的，廠家也會依據建筑需求停止科學的骨架配置。裝修用的GRC構件應該是glass-fiber reinfored concrete. 既增加型玻璃纖維混凝土,里面的C for concrete, not for cement.
