摘　　要：近几年来，花岗石已广泛用于外墙饰面，但还存在不少问题， 如采用旧的安装工艺导致变色； 干挂法工艺需解决可靠性及防污染、防水问题；采用烧毛后的花岗石，其强度有可能下降等。针对存在的问题，建议外墙保温层与干挂花岗石相结合，光面与毛面相结合，挂、粘相结合。During recent years,granite has been widely adopted for external wall' s facing blocks and decoratives.Nevertheless,there are yet some problems to be contemplated,namely:1,the old erection installation technology would cause its colour fading and deterioration 2,dry hanging method technology should have solved its problems of reliability,pollution-proof and water-proof 3,granite after heat-treatment would be some what reduced in its strength.According to the above-mentioned problems,it is suggested that the integrations and integrities of its insulation layer with dry hanging granite,its finely polished surface with coarsely polished surface granites,its dry hanging method with gluing method should be performed and eventually,attention should be paid to the problems of its temperature stress.
