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是由波蘭特水泥砂漿與抗堿玻纖組成的一種復(fù)合材料，它的基本組成材料為水泥、砂子、纖維和水，另外還添加有聚合物、外加劑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鋁酸鹽水泥、低堿度硫鋁酸鹽水泥、普通硅酸鹽水泥、白色硅酸鹽水泥。

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

纖維：GRC材料中使用的纖維必須是耐堿玻璃纖維，種類包括耐堿玻璃纖維無捻粗紗、耐堿玻璃纖維短切紗、耐堿玻璃纖維網(wǎng)格布。歐美要求GRC中使用的玻璃纖維氧化鋯含量不低于16.5%，國內(nèi)要求在使用普通硅酸鹽水泥時氧化鋯含量不低于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：通常添加的聚合物為丙乳，即丙烯酸酯共聚乳液。

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

外加劑：通常可選擇性地加入減水劑、塑化劑、緩凝劑、早強(qiáng)劑、防凍劑、防銹劑等外加劑，當(dāng)制品中含有鋼質(zhì)增強(qiáng)材料或鋼質(zhì)預(yù)埋件時，不得使用氯化鈣基的外加劑。

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：可以選擇性的添加一些火山灰質(zhì)活性材料，有利于提升GRC制品的綜合性能，例如強(qiáng)度、抗?jié)B、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.

而水泥構(gòu)件卻相對簡單，主要由水泥、砂子、河石、水等通過比例混合而成的，二者比較起來，GRC構(gòu)件的組成成分相對復(fù)雜一些。因此，GRC的特性也比水泥要優(yōu)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.
