GRC构件相比较水泥构件有哪些优势?

来源:http://www.aswjc.com/ 发布人:aisaiwen 发布时间:2020-05-21

GRC构件和水泥构件在日常建筑生产中应用都比较广泛。我们可从它们的组成成分、性能以及用途上加以对比。
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。欧美国家要求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高效减水剂、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.

2、材料性能
2. Material properties
水泥构件具有强度高、耐候性强、施工维护方便、性价比高等特性。
Cement component has the characteristics of high strength, strong weather resistance, convenient construction and maintenance, high cost performance.
GRC则具有以下优点:
GRC has the following advantages:
①质量轻、强度高:GRC的体积密度约为1.8-1.9,8mm,厚标准GRC板重量仅为15kg,抗压强度超过40Mpa,抗弯强度超过34Mpa,大大超过国际标准要求。
① Light weight and high strength: the volume density of GRC is about 1.8-1.9,8mm, the weight of thick standard GRC plate is only 15kg, the compressive strength is more than 40MPa, and the bending strength is more than 34mpa, which greatly exceeds the requirements of international standards.
②工期短、维护方便、易更换:GRC可大块生产分割,安装方法简便多样,且全部为工厂预制,有利于现场施工,大大缩短工期。
② Short construction period, convenient maintenance and easy replacement: GRC can be divided into large blocks for production, simple and diverse installation methods, and all of them are factory prefabricated, which is conducive to site construction and greatly shortens the construction period.
③防火、防水:GRC原材料全部为不燃材料,经检测为A1级防火材料;在水中长期浸泡,GRC材料的形状及安全性系数变化很小,结构和性能均不发生变化。
③ Fire and waterproof: GRC raw materials are all incombustible materials, which are tested as class A1 fire-resistant materials; after long-term immersion in water, the shape and safety coefficient of GRC materials change little, and the structure and performance do not change.
④抗污、不变形、超耐久:GRC材料干湿变形小于0.123%,经过大量实验证明,GRC具有超强的耐久性,不怕紫外线照射,经得起风吹日晒雨淋,耐候性远远高于一般的建筑材料。
④ Anti pollution, non deformation and super durability: the dry and wet deformation of GRC material is less than 0.123%. Through a large number of experiments, GRC has super durability, is not afraid of ultraviolet radiation, can stand the wind, the sun and the rain, and its weather resistance is far higher than the general building materials.
⑤环保、无辐射:GRC属可再生材料,有利于环保。原材料不含有放射性核元素,为国家放射性核素含量A类环保材料。
⑤ Environmental protection, no radiation: GrC is a renewable material, which is conducive to environmental protection. The raw materials do not contain radioactive nuclear elements, which are class a environmental protection materials with national radionuclide content.
⑥无限可塑性:GRC产品是将原料按一定配比搅拌,在模具内浇筑成型,可生产出造型丰富,质感多样的产品。可根据客户和设计师的不同需要,进行任意的艺术造型,完美实现设计师的设计梦想。
⑥ Infinite plasticity: GRC products are made by mixing raw materials in a certain proportion, casting and forming in the mold, which can produce products with various shapes and textures. According to the different needs of customers and designers, we can carry out any artistic modeling to achieve the designer's design dream perfectly.
⑦超薄技术、尺寸大:GRC板最薄可做到5mm,标准宽度为900mm和1200mm,长度不限,满足运输条件即可,亦可做成5mm至任意厚度,任意尺寸。
