前言GRC(Glassfiber Reinforced Cement)即玻璃纤维增强水泥,它是新近发展起来的一种新型建筑材料,具有轻质、高强、高韧性的优点。建材研究院对它进行了近10年的研究,现已获得成功。本文所谈的 GRC 复合外墙板就是用这种新型材料作墙板的外壳(壳厚通常为10mm 左右),中间填以保温材(岩棉或膨胀珍珠岩水泥 Foreword GRC (Glassfiber Reinforced Cement) is a glass fiber reinforced cement. It is a new type of building material that has recently been developed and has the advantages of light weight, high strength, and high toughness. The Institute of Building Materials carried out nearly 10 years of research on it and has now achieved success. The GRC composite exterior wallboard discussed in this paper is the shell of this type of new material (the shell thickness is usually about 10mm), filled with insulation material (rock wool or expanded perlite cement
