【摘要】 抗钻强度测试是一种极微小破坏性的强度测试方法 ,特别适合于文物保护中加固强度及加固剂渗透深度的测定。通过用有机氟材料对几种不同材质文物 (石质、砖或陶质、土质 )在实验室和现场加固强度及渗透深度的测试 ,并与抗压强度进行比较 ,结果表明抗钻强度是一种有效的加固强度表征方法 ,特别适合于文物的现场保护应用。更多还原

【Abstract】 The drilling resistance measurement is a minimally destructive test method that is going to be an effective way used for consolidation protection of heritage,especially for the measurement of strength and penetration depth.Its main applications in the sand stone,brick as well as earthen materials in the laboratory and insitu after consolidation with fluorinated polymer have been carried out in this paper.The compressive strength has also been investigated in order to find a correlation between the compressive strength and drilling resistance for untreated and treated materials.The investigation results indicate that the drilling resistance is suitable for the application of consolidation to assess the penetration depth and consolidation strength.It gives drill holes of just 3 mm in diameter, which is its significant advantage for insitu use.更多还原
