GRC在建筑行业中已得到越来越广泛的应用，那到底它是如何制成的呢？
GRC has been more and more widely used in the construction industry, so how is it made?
GRC是由波兰特水泥砂浆与抗碱玻纤组成的一种复合材料，其中还含有掺和料与外加剂。它的组成成分通常有：水泥、纤维、聚合物、外加剂和其他材料。快硬硫铝酸盐水泥、低碱度硫铝酸盐水泥、普通硅酸盐水泥、白色硅酸盐水泥都是常用的水泥品种。GRC材料中使用的纤维是耐碱玻璃纤维。
GRC is a kind of composite material composed of Polish cement mortar and alkali resistant glass fiber, which also contains admixture and admixture. It is usually composed of cement, fiber, polymer, admixture and other materials. Fast hardening sulphoaluminate cement, low alkalinity sulphoaluminate cement, ordinary portland cement and white portland cement are all commonly used cement varieties. The fibers used in GRC materials are alkali resistant glass fibers.
GRC主要用两种方法来制作：①喷射法：用手工或机械方法使纤维与料浆同时喷射到模具上，可以用来制作农业用构件、筒体、幕墙板、通风道与模板等。②预拌法：使纤维与料浆预拌后，再浇注于模具上，通常均使之振动。可以用来制作挡阳板、种植盆、变电房、接线箱以及排水构件等。
GRC is mainly produced by two methods: ① spraying method: manually or mechanically spraying fiber and slurry to the mold at the same time, which can be used to make agricultural components, cylinder, curtain wall plate, ventilation channel and formwork, etc. ② Premixing method: after the fiber and slurry are premixed and then poured on the mold, they are usually vibrated. It can be used to make sun blocking plate, planting basin, substation, junction box and drainage components.
采用喷射法制作GRC时，水泥砂浆与切短了的AR-玻纤同时由喷射头中喷合适的模具上。水泥砂浆由可调节的泵喂入喷射枪中并由压缩空气使之分散成为微粒状。AR-玻纤无捻粗纱喂入装于喷射头的切割预定的长度，使切短的原纱喷入分散的砂浆中，从而在模具上可形成均质的纤维砂浆料层。
When the GRC is made by spraying method, the cement mortar and the chopped ar glass fiber are sprayed to the appropriate mold from the spraying head at the same time. The cement mortar is fed into the spray gun by an adjustable pump and dispersed into particles by compressed air. Ar - glass fiber roving is fed into the cutting of the spray head to a predetermined length, so that the cut short raw yarn is sprayed into the dispersed mortar, so that a uniform fiber sand slurry layer can be formed on the mold.
喷射法也分为几种。使用手工喷射法，是由操作人员直接将料流喷射于模具表面上，直达到一定的厚度。通过压辊使料层与模具的形状完全一致，水泥砂浆渗进纤维中，排除空气并使料层达到要求的密实度。而机械喷射法主要用于生产平直的或外形较浅的制品。模具在辊道或水平皮带上前进过程，经由一位于其上的装有喷射头的一横向移动的系统。可将纤维水泥砂浆混合料喷射模具上。还有喷射-脱水法，可以先用机械喷射法制成连续的GRC料层，然后使之脱水形成具有一定塑性的板坯。
The jet method is also divided into several types. Using the manual spraying method, the operator directly sprays the material flow on the surface of the mold until it reaches a certain thickness. By pressing the roller, the shape of the material layer and the mold is completely consistent, the cement mortar infiltrates into the fiber, exhausts the air and makes the material layer reach the required compactness. The mechanical spraying method is mainly used to produce flat or shallow products. The die moves forward on the roller table or horizontal belt through a lateral moving system equipped with a jet head. The fiber cement mortar mixture can be sprayed onto the mold. There is also jet dehydration method, which can be used to form a continuous GRC layer by mechanical jet method, and then dehydrate it to form a plastic slab.
预拌法是使水泥、砂、水、外加剂于短切的AR-纤维原砂在一搅拌机内混合后，再进行成型。要制成高质量的料浆，不仅具有必要的工作性，同时还可使纤维均匀分散其中；其次将纤维混入料浆中。根据成型方法的不同，预混工艺可分为预混浇筑工艺和预混喷射工艺。预混浇筑工艺与预制混凝土制品的工艺相类似，在浇筑过程中常常会辅以震动工序。
The premixing method is to mix the cement, sand, water and admixture in the short cut ar fiber raw sand in a mixer, and then form. First of all, it is necessary to make high-quality slurry, which not only has the necessary workability, but also can make the fiber disperse evenly; secondly, the fiber is mixed into the slurry. According to the different forming methods, the premixed process can be divided into premixed pouring process and premixed spraying process. The process of premixed pouring is similar to that of precast concrete products, and vibration process is often supplemented in the process of pouring.
