对不同处理方式和表面涂层的角接缝进行人工风化。风化后的试样在胶合缝的开度上有明显的差异。这些样品的吸水性是在viligen （CH）的Paul-Scherrer-Institute用中子射线照相法确定的。通过中子射线照相法的研究，可以追溯样品的吸水率，并对吸水量作出说明。但由于在吸水过程中溶胀所造成的尺寸不稳定，尚不能确定定量。结论中将提出进一步改进方法的展望。
Corner joints with different treatments and surface coatings were artificially weathered. After the weathering the samples showed conspicuous differences in the opening of the glued joints. On these samples the water uptake was ascertained at the Paul-Scherrer-Institute in Villigen (CH) by means of neutron radiography. The neutron radiographic investigation made it possible to retrace the water absorption by the samples and to make statements on the quantity of the absorbed water. Still it was not possible to make definite quantification due to dimensional instability which results of the swelling process during the water absorption. An outlook for further methodical improvements will be given in the conclusions.
