GRC 性能
（ 1 ） 轻质： GRC 材料容重 1.8-2.0g / ㎝ 3 ，比钢筋砼轻 1/5 ，由于可制成薄壁空体制品，比实体制品重量大幅度降低。
（ 2 ） 高强 -- 加入玻纤后，水泥砂桨的抗弯强度从 2-7MPa 提高到 6-30Mpa ，加之，制品断面多为空体曲面，惯性矩大， 抗弯强度 高。
（ 3 ） 抗冲击好 -- 由于大量玻纤以三维状分布在 GRC 产品中，使产品韧性好，因此能够吸收冲击作用的能量，提高抗冲击性能。国内检测结果表明，抗冲击强度由 1- 2 ㎏ / ㎝ 2 提高到 5-15 ㎏ / ㎝ 2 。
（ 4 ） 抗渗、抗裂性能好 -- 因玻璃纤维大量细密面均匀的分布在制品的各个部位，形成了网状增强体系，延缓裂缝的出现和发展，减轻应力集中现象，提高了抗渗抗裂性能。
（ 5 ） GRC 材料耐水、耐火，抗冻融，并且有良好的可加工和可模塑性。

GRC properties
Good impact resistance-for the three-dimensional distribution of most glass fibers in GRC products,the tensile and flexural strengths are very well which are capable for GRC products to absorb energy from impacting effect,increasing the impact resistence.Test result in China indicates that impact resistance can be increased from 1- 2 ㎏ / ㎝ 2 to 5-15 ㎏ / ㎝ 2 。
High strenth-after adding glass fiber,bending strength will be increased from 2-7Mpa to 6-30Mpa ， for the most sections of products are hollow and curved surface ,so inertial f orce is strong ,and the compressive strength is high.
Light weight: weight for GRC materials is1.8 -2.0g / ㎝ 3 ， 1/5 lighter than reinforced concrete,can be fabricated into hollow products with thin wall which are much lighter than solid products.
Propeties of penetrability resistance and rapture resistance are well –for the close and uniform distribution of large quantities of glass fibers on all parts of products,forming the web reinfocing system,retarding the appearance and development of cracks,reducing the concentration of stress strength,improving the propeties of penetrability resistance and rapture resistance.
GRC have the good properties of waterproofing,fireproofing,freeze-thaw resisitance,good abilities of machining and modeling.
