Experiences made during construction of parking garages raised repeatedly controversial discussions among the engineers concerned, despite the rules and explanations given in the DBV Information Sheet and in DIN 1045-1 together with the comments published in DAfStb Reports No. 525 and No. 526. Recommendations and interpretations shall be consistent and unambiguous, however, and they shall represent the generally accepted state-of-the-art of science and technology. In order to locate the actual situation and learn the opinion of experts, DAfStb has organized two specific colloquia. As a result of these two meetings DAfStb has recommended that the content of DAfStb Report No. 600 and the modifications published in the DBV Information Sheet shall be discussed in the appropriate standards committees and results shall be integrated in the national appendix of DIN EN 1992-1-1. Based on the results of the two colloquia, DAfStb has accepted the task to do the necessary preparatory work. In this contribution the actual state of the consultations within DAfStb shall be outlined.
尽管DBV信息表和DIN 1045-1中给出了规则和解释，以及DAfStb第525号和第526号报告中发表的评论，但在停车场建设过程中取得的经验在有关工程师中引起了反复的争议性讨论。但是，建议和解释应是一致和明确的，并应代表普遍接受的科学和技术的最新水平。为了定位实际情况，了解专家的意见，DAfStb组织了两次专门的座谈会。由于这两次会议的结果，DAfStb建议，DAfStb第600号报告的内容和在DBV信息表中公布的修改应在适当的标准委员会中讨论，结果应纳入DIN EN 1992-1-1的国家附录。根据两次座谈会的结果，科技部已接受任务，做好必要的准备工作。在本报告中，将概述在该部内部进行协商的实际情况。

Corrosion of steel elements in masonry and concrete structures is a major cause of material and structural damage. Typical steel and iron corrosion damage phenomena are presented. The basic principles of active and passive cathodic protection are explained, and examples of how cathodic protection can be applied to steel reinforcement in reinforced concrete as well as to steel elements in masonry constructions are discussed.

The weathering of a given rock has been previously reported to be a result of many processes acting on it but one of them should dominate based on the prevailing environmental conditions at this site. In case of salt weathering, it has been reported to be prevailing and destructive for a wide range of materials but its regime has received little attention particularly ranking of salt weathering regimes on a given rock. Not only that but also the same salt differs in its impact on a given rock rather than other one based on the rock's properties and the acting weathering regime. The current study aims to compare and rank rock's damage by salts at five weathering regimes (that imitate all possible regimes in the world particularly in the Middle-East and Europe) using sodium and magnesium sulfates. The rock's pore size distribution "PSD" has been measured using mercury intrusion porosometry "MIP" before and after conducting the artificial weathering to find out rock's Salt Susceptibility Index "SSI" to be correlated with rock's damage visually recorded and numerically expressed by samples' weight loss at the end of each regime. The rock's weathering on micro-scale as well as salt's form and distribution have been investigated using scanning electron microscope "SEM" along profiles scanned on nano-scale from sample's surface to its deep inside. This is finally to rank weathering regimes on one hand and to rank the severity of these salts on the other hand. Also, to find out the rock's pore size that controls rock's susceptibility to salt weathering. This study enables a best choice for limits of rock properties in case of its use for reconstruction of archaeological sites at salty environments with regimes as that conducted in the current study. The results indicated that SCI-S15 is the most aggressive weathering regime, particularly with sodium sulfate, followed by CPI 12-12, particularly with sodium sulfate, but the least has been recorded for samples exposed to CPI, particularly with magnesium sulfate, CPI-CC, particularly with sodium sulfate, and CPI-HC, with both salts. Sodium sulfate is almost more destructive than magnesium sulfate for such rock but to have a clear view in ranking these two salts they must be applied for other facies in another study.
