Mathematical modelling of sustainable bioresidual concrete

Autor: Tuovinen, Tero, Leppänen, Teemu, Parkkonen, Joni, Virkajärvi, Jussi, Turunen, Leena

In the production of cement, which is the main component of concrete production, the process generates about 5% of the global carbon dioxide emissions. In addition, bioproduct and pulp mills produce signi_cant quantities of soda ash and bio-ash, whic

Publikováno v: Kuva, J, Sammaljärvi, J, Parkkonen, J, Siitari-Kauppi, M, Lehtonen, M, Turpeinen, T, Timonen, J & Voutilainen, M 2018, ' Imaging connected porosity of crystalline rock by contrast agent-aided X-ray microtomography and scanning electron microscopy ', Journal of Microscopy, vol. 270, no. 1, pp. 98-109 . https://doi.org/10.1111/jmi.12661

We set out to study connected porosity of crystalline rock using X‐ray microtomography and scanning electron microscopy with energy dispersive X‐ray spectroscopy (SEM‐EDS) with caesium chloride as a contrast agent. Caesium is an important radio
