AB On the one hand, calcium sulfoaluminate (CSA) eco-cements release about 40% less carbon dioxide (CO2) than Portlandcement during fabrication; on the other hand, phase change materials dispersed in a cementitious matrix can help tooptimise the indoor temperature of buildings, reducing carbon dioxide emissions related to heating/air conditioning.However, this is only economically viable if it is used as a thin layer (a coating). In addition, the combination of bothmaterials supposes a double environmental benefit. Consequently, the main objective of this work is the preparation ofa suitable homogeneous and well-adhered bilayer sample, composed of CSA and CSA-MPCM. To achieve this, in the firststep, the effect of pH, temperature and stirring was studied for microencapsulated phase change material (MPCM)aqueous suspensions (47.3 wt%); second, the MPCM (45 wt% with respect to dry cement) was dispersed in a CSA paste;then, in a third step, a homogeneous well-adhered coating of CSA-MPCM, with undamaged MPCM, was obtained on aCSA matrix. This was achieved through rheological measurements and checked by microscopy. Finally, the correspondingCSA and CSA-MPCM mortars were characterised through their mechanical properties (compression) (70 and 13 MPa at 7days, respectively) and thermal conductivity (2.06 and 1.19 W/mK, respectively).
