一、从材料上分析：
1、 Material analysis:
grc构件一种纤维水泥复合材料，以耐碱玻璃纤维为增强材料，水泥砂浆为基体，而水泥构件相对简单，主要采用水泥、砂子、河石、水等按比例混合而成，二者比较， grc构件的材料相对复杂。
GRC component is a kind of fiber cement composite material, which takes alkali resistant glass fiber as reinforcement and cement mortar as matrix. The cement component is relatively simple, mainly composed of cement, sand, river stone and water in proportion. Compared with the two, the material of GRC component is relatively complex.
grc组件材料组成：
GRC component material composition:
1、水泥：快硬硫铝酸盐水泥、低碱度硫铝酸盐水泥、普通硅酸盐水泥、快硬硫铝酸盐水泥、普通硅酸盐水泥等常用的水泥。
1. Cement: quick hardening sulphoaluminate cement, low alkalinity sulphoaluminate cement, ordinary portland cement, quick hardening sulphoaluminate cement, ordinary portland cement and other commonly used cement.
2、纤维： grc材料所用的纤维应为耐碱玻璃纤维，种类有耐碱玻璃纤维无捻粗纱、耐碱玻纤短切纱、耐碱玻纤网布。在欧美中，玻璃纤维氧化锆的使用量应不低于百分之16.5，要求在使用普通硅酸盐水泥时应不低于百分之16.5。
2. Fiber: the fiber used for GRC material shall be alkali resistant glass fiber, including alkali resistant glass fiber untwisted roving, alkali resistant glass fiber chopped yarn and alkali resistant glass fiber mesh. In European and American countries, the use of glass fiber zirconia shall not be less than 16.5%, and China requires that the use of ordinary portland cement shall not be less than 16.5%.
3、聚合物：常用的聚合物是丙乳，共聚丙烯酸酯乳液。
3, polymer: the commonly used polymer is acrylic emulsion, copolymer acrylic emulsion.
4、掺合料：减水剂、塑化剂、缓凝剂、早强剂、防冻剂、防锈剂等外加剂：当产品中含有钢质增强材料或预埋件时，不能用氯化钙作为外加剂。
4. Admixtures: water reducing agent, plasticizer, retarder, early strength agent, antifreeze, antirust agent and other admixtures: when the product contains steel reinforcement materials or embedded parts, calcium chloride cannot be used as the admixture.
5、其它材料：可选择性地添加一些火山灰质活性物质，有助于提高产品的综合性能，如强度、抗渗、耐久性等。
5. Other materials: some pozzolanic active substances can be selectively added to help improve the comprehensive properties of the product, such as strength, impermeability, durability, etc.
二、特征对比：
2、 Feature comparison:
grc构件具有强度高、耐候性强、施工维修方便、性价比高等特点，而水泥构件则具有防火、防水、、防污、隔音、抗震、多样等诸多特点，是水泥构件无法比拟的。
GRC components have the characteristics of high strength, strong weather resistance, convenient construction and maintenance and high cost performance, while cement components have many characteristics, such as fire prevention, waterproof, environmental protection, antifouling, sound insulation, earthquake resistance and diversity, which are unmatched by cement components.
三、从使用角度对比：
3、 From the perspective of use:
水泥件一般包括水泥彩砖、水泥管件、水泥盖板、异形水泥构件、路沿石、挡土墙人孔盖、钢筋混凝土上浮、草坪砖、路面砖、加气砖、电缆盖板、检查口、路沿石等，都是生活中比较实用的材料;
Cement parts generally include cement colored bricks, cement pipe fittings, cement cover plates, special-shaped cement components, curb stones, manhole covers of retaining walls, reinforced concrete floating, lawn bricks, pavement bricks, aerated bricks, cable cover plates, inspection ports, curb stones, etc., which are all practical materials in life;
grc构件集中在建筑物的外部装饰上， grc构件是用 grc装饰的建筑物，外表华丽大气，具有很高的艺术欣赏价值，如罗马柱、窗套、窗套、装饰线等都属于 grc构件。
GRC components focus on the external decoration of buildings. GRC components are buildings decorated with GRC, with gorgeous appearance and high artistic appreciation value. For example, roman columns, window sleeves, window sleeves, decorative lines and so on belong to GRC components.
