ABSTRACT
The number of construction sites that need specific soil treatment to improve their load-bearing capacity is rising. An original soil reinforcement technique called Controlled Modulus Columns (CMC) was developed in 1994 by the Menard company and consists of a network of thin mortar columns. In a previous laboratory work, cement-based composite appropriate for CMC applications was designed using innovative materials. Due to the specific CMC casting conditions, and especially given the inherent risk of segregation, the validation of the properties of the material produced and implemented in industrial conditions was required. This contribution presents the properties of CMC mixes in lab conditions. Similar mixes were produced in industrial conditions and used to build 12 m deep columns. A series of tests were carried out on these materials in both the fresh and hardened state. The results show that tightly controlled site conditions do not significantly affect the properties of the material.
