GRC components and cement components are widely used in daily construction production. We can compare their composition, performance and application.

1、材料成分

1. Material composition

GRC是由波兰特水泥砂浆与抗碱玻纤组成的一种复合材料，它的基本组成材料为水泥、砂子、纤维和水，另外还添加有聚合物、外加剂等用于改善后期性能的材料。

GRC is a kind of composite material composed of Polish cement mortar and alkali resistant glass fiber. Its basic materials are cement, sand, fiber and water. In addition, polymer and additives are added to improve the later performance of the material.

水泥：通常用于GRC中的水泥主要有快硬硫铝酸盐水泥、低碱度硫铝酸盐水泥、普通硅酸盐水泥、白色硅酸盐水泥。

Cement: the cement commonly used in GRC mainly includes fast hardening sulphoaluminate cement, low alkalinity sulphoaluminate cement, ordinary portland cement and white portland cement.

纤维：GRC材料中使用的纤维必须是耐碱玻璃纤维，种类包括耐碱玻璃纤维无捻粗纱、耐碱玻璃纤维短切纱、耐碱玻璃纤维网格布。欧美要求GRC中使用的玻璃纤维氧化锆含量不低于16.5%，国内要求在使用普通硅酸盐水泥时氧化锆含量不低于16.5%。

Fiber: the fiber used in GRC material must be alkali resistant glass fiber, including alkali resistant glass fiber roving, alkali resistant glass fiber chopped yarn and alkali resistant glass fiber mesh. European and American countries require that the zirconia content of glass fiber used in GRC shall not be less than 16.5%, and domestic requirements shall not be less than 16.5% when using ordinary portland cement.

聚合物：通常添加的聚合物为丙乳，即丙烯酸酯共聚乳液。

Polymer: the commonly added polymer is acrylic emulsion, that is, acrylate copolymer emulsion.

外加剂：通常可选择性地加入减水剂、塑化剂、缓凝剂、早强剂、防冻剂、防锈剂等外加剂，当制品中含有钢质增强材料或钢质预埋件时，不得使用氯化钙基的外加剂。

Admixtures: generally, admixtures such as superplasticizer, plasticizer, retarder, early strength agent, antifreeze, antirust agent can be added selectively. When the products contain steel reinforcing materials or steel embedded parts, calcium chloride based admixtures shall not be used.

其他材料：可以选择性的添加一些火山灰质活性材料，有利于提升GRC制品的综合性能，例如强度、抗渗、耐久等。

Other materials: some pozzolanic active materials can be added selectively, which is conducive to improving the comprehensive performance of GRC products, such as strength, impermeability, durability, etc.

而水泥构件却相对简单，主要由水泥、砂子、河石、水等通过比例混合而成的，二者比较起来，GRC构件的组成成分相对复杂一些。因此，GRC的特性也比水泥要优越。

However, the cement component is relatively simple, which is mainly composed of cement, sand, river stone, water and so on. Compared with them, the composition of GRC component is relatively complex. Therefore, the properties of GRC are better than that of cement.
