JUSTNES, Harald
Production of cement is ranking 3rd in causes of man-made carbon dioxide emissions world-wide. Thus, in order to make concrete more sustainable one may work along one or [...]

|
The definition of the composition, the technological process and, last but not least, the provenance of the raw materials of historical mortars is still difficult and uns [...]

|
This study rises from the perplexity about the adoption of standardized methods for the evaluation of mortar behaviour towards water. Standards are often not very specifi [...]
