''' Abstract  '''
 
This paper reports on our preliminary attempt to perform dynamic laboratory measurements of salt crystallization and subsequent deliquescence on a surface of a porous material specimen (autoclaved aerated concrete as a model material) by using a high-resolution digital optical microscope that allows generating three-dimensional images. A specimen that is initially filled with a NaCl solution is dried in a room at ~26°C and ~40% RH for 14 days and is then wetted in a desiccator at ~95% RH during the next 14 days. A temporal change of the spatial distribution of the volume occupied by salt crystals on the specimen surface is determined based on the contrast between two microscopic images successively taken with a certain interval of time. The mass of the specimen is also measured simultaneously to determine the rate of water evaporation/absorption. The results show that salt crystallization during drying is not spatially uniform throughout the specimen surface, which likely depends on the spatial distribution of the pore structure in the specimen, and salt crystal deliquesces faster near the edges of the specimen than in the centre, which indicates a stronger dependency of salt deliquescence on the geometry of the specimen than on the inner pore structure of the specimen.

Classification of an article in SaltWiki[edit]

Each article tackles a self-contained subject. Explanations of terms can generally be found in the glossary. A Wiki article concentrates on the actual content and is linked to all subjects that are required or are important for understanding the article.
The classification could look as follows (for example, see the article on render/mortar): Each page starts with the page head, as proposed below.

== Abstract ==
== Introduction ==
== Main chapter ==
=== Sub-chapter ===
== Web links ==
== Literature ==

<bibprint/> : to use if at least one quote in Bibtex format is present in the text, 
              otherwise the complete list of references is displayed!


If there are more than three headings, then the software will automatically create a table of contents inserted before the first heading.

Embedding photos in a text[edit]

To embed a photo in a Wiki page, please use this template, insert the name of your illustration and amend the formatting details, as explained in more detail below.

[[Image:''full name of the photo''|thumb|center|300px|caption]] 
  • thumb: States that the illustration is embedded in a reduced size, given in px = Pixelsl
  • center: center
  • left: left
  • right: right
  • 300px : The image width is 300 pixels; can be amended to meet your own requirements
  • caption: The illustration caption is entered here

Embedding videos[edit]

As previously only videos in the format "OGG" were able to be embedded, only videos in this format should be uploaded.

Videos in the ".ogg" format can be viewed directly on the pages. To do this, enter the following:

[[image:"name of the video".ogg]] 

e.g.

[[image:MgSO4_Kristallisationsvideo.ogg]] 

Detailed information on the width, etc., as under "Embedding photos" using, as an example

with

[[image:MgSO4_Kristallisationsvideo.ogg|thumb|300px|Figure 1:Crystallisation of Magnesiumsulfat]]

the video will be shown as follows.

Error creating thumbnail:
Figure 1: Crystallisation of Magnesiumsulfat



Weblinks[edit]

<references/>  //all "footnotes" will be shown

DynamicPageList[edit]

Using the "DynamicPageList", it is possible to generate compilations of everything that is tagged using categories, e.g. all pages in the category "Niter" are listed with the following details:

<dpl>
  category = Niter
  format   = ,\n* [[%PAGE%]],,
</dpl>

The list (if input available):

Create a new list/table based on tables in different articles[edit]

With the extension DynamicPageList it is also possible to create lists from tables based on the same template according to the variables used there.

Here's an example: With the entries in the "info box" of the nitrate salts create a new, sortable table with the columns birefringence, refractive indices, molar volume, solubility and deliqueszenzhumidity.

The following DPL statements :

<dpl>
category        = Nitrat&Salt
include         = {Infobox_Salt}:birefringence:refractive_indices:molvolume:solubility :deliqueszenzhumidity
table           = class="wikitable sortable" ,birefringence,refractive_indices,molvolume,solubility,deliqueszenzhumidity
tablerow        =%%,bgcolor=lightyellow|%%,bgcolor=lightyellow|%%,bgcolor=lightyellow align=center|%%,bgcolor=lightyellow|%%
suppresserrors  = true 
</dpl>

You will get the resulting table (if input available):

Abstract

This paper reports on our preliminary attempt to perform dynamic laboratory measurements of salt crystallization and subsequent deliquescence on a surface of a porous material specimen (autoclaved aerated concrete as a model material) by using a high-resolution digital optical microscope that allows generating three-dimensional images. A specimen that is initially filled with a NaCl solution is dried in a room at ~26°C and ~40% RH for 14 days and is then wetted in a desiccator at ~95% RH during the next 14 days. A temporal change of the spatial distribution of the volume occupied by salt crystals on the specimen surface is determined based on the contrast between two microscopic images successively taken with a certain interval of time. The mass of the specimen is also measured simultaneously to determine the rate of water evaporation/absorption. The results show that salt crystallization during drying is not spatially uniform throughout the specimen surface, which likely depends on the spatial distribution of the pore structure in the specimen, and salt crystal deliquesces faster near the edges of the specimen than in the centre, which indicates a stronger dependency of salt deliquescence on the geometry of the specimen than on the inner pore structure of the specimen.

== Abstract  ==
This paper reports on our preliminary attempt to perform dynamic laboratory measurements of salt crystallization and subsequent deliquescence on a surface of a porous material specimen (autoclaved aerated concrete as a model material) by using a high-resolution digital optical microscope that allows generating three-dimensional images. A specimen that is initially filled with a NaCl solution is dried in a room at ~26°C and ~40% RH for 14 days and is then wetted in a desiccator at ~95% RH during the next 14 days. A temporal change of the spatial distribution of the volume occupied by salt crystals on the specimen surface is determined based on the contrast between two microscopic images successively taken with a certain interval of time. The mass of the specimen is also measured simultaneously to determine the rate of water evaporation/absorption. The results show that salt crystallization during drying is not spatially uniform throughout the specimen surface, which likely depends on the spatial distribution of the pore structure in the specimen, and salt crystal deliquesces faster near the edges of the specimen than in the centre, which indicates a stronger dependency of salt deliquescence on the geometry of the specimen than on the inner pore structure of the specimen.
