All the e-mail addresses of the authors sould be given at the beginning of the manuscript.

If there exists a conflict of interest, it should be clearly stated in a dedicated section at the end of the manuscript.

In addition, please submit a cover figure that will appear in the table of contents (to be pasted in the manuscript). This figure should have 3:2 aspect ratio (landscape-oriented).


Please place all the figures, illustrations and tables within the text at the appropriate points, rather than at the end.
When possible, the graphs should be pasted as enhanced metafile pictures.The text on the figures should be large enough to be readable when the figure is formatted to the width of 8 cm (single column) or 16 cm (double column). The minimum text size is e.g. Arial 7 pt or Calibri 7 pt.

RILEM Technical Letters is an open access journal. In order to avoid conflicts of interests with other publishers, please do not reproduce figures from other publications.


Please use designated tool for the equations. The equations should be editable in the document.
