In the context of an experimental programme on the use of macrosynthetic fibre reinforced concrete (MSFRC) for casting building partition walls, three walls from a residential building in Switzerland were selected for an onsite application (with lengths varying between 2.8 and 13 m). The walls had an amount of fibres equal to 4 kg/m3 and only conventional reinforcement at the construction joints with adjacent walls. In addition, specimens were cast in order to measure the strength, rheological properties and characterise the post-cracking behaviour of MSFRC. A crack monitoring protocol was conducted on the walls for crack detecting and tracking their evolution over time, with no noticeable cracks in the short walls. The cracks detected for the 13 m-long wall were measured and the results summarized in this document. This research contribution aims at showcasing the use of MSFRC as an alternative to ordinary reinforcement for building partition walls
