Construction damage

It is therefore the conviction of the author that the high humidity, the relatively long lasting alkalinity of the cement plaster used in these mortuaries of crematoria II and III, in combination with the realistic homicidal gassing scenarios (high HCN concentrations, slow ventilation process) would have led to the formation of long-term stable cyanide compounds in an amount that should be easily detectable still today. Not at least because the conditions of these mortuaries are very similar to those described in the construction damage case referred to before,102 which is quoted entirely and henceforth analyzed in Appendix 1 of this volume. 

Remember to remove labels and to check wrapped or staked trees frequently, loosening the ties, if necessary. Whenever possible, protect trees from construction damage by roping off a large area around them, so trucks won t compact the soil around the roots or hit the tree. 

Our future can be summed up in the words of an Inuit from the tribes of Northern Canada 7 want to cause constructive damage to the status quo. 

Because of the trend towards shorter and faster product development cycles, field data sources are more important than in the past Based on statistical analysis in an early phase of construction, damage cases can be predicted in an early stage and verified by technical product analysis. 

Ceramic or carbon-brick linings are frequently used as facing linings over plastic or membrane linings when surface temperatures exceed those which can be handled by the unprotected materials or when the membrane must be protec ted from mechanical damage. This type of construction permits processing of materials that are too corrosive to be handled in low-cost metal constructions.

Damage Limiting Construction Construction of equipment (building) with weak sections to limit the damage to the equipment (building). The weak sections fail early and prevent damage to the rest of the equipment (building). 

Heterogeneous surface areas consist of anodic regions at corrosion cells (see Section 2.2.4.2) and objects to be protected which have damaged coating. Local concentrations of the current density develop in the area of a defect and can be determined by measurements of field strength. These occur at the anode in a corrosion cell in the case of free corrosion or at a holiday in a coated object in the case of impressed current polarization (e.g., cathodic protection). Such methods are of general interest in ascertaining the corrosion behavior of metallic construction units... 

With impressed current stations on privately owned sites, it is advisable to conclude contracts with the property owner in order to guarantee access to the installation at all times, to prevent damage to the cables and to exclude construction or modifications in the area of the anode beds. 

A diagnosis of possible damage should be made before beginning repairs with other construction measures [48,49]. There should be a checklist [48] of the important corrosion parameters and the types of corrosion effects to be expected. Of special importance are investigations of the quality of the concrete (strength, type of cement, water/cement ratio, cement content), the depth of carbonization, concentration profile of chloride ions, moisture distribution, and the situation regarding cracks and displacements. The extent of corrosion attack is determined visually. Later the likelihood of corrosion can be assessed using the above data.
