Expanded vermiculite was added to the cement-lime mortar at 10%, 20% and 30%, which reduced the density of the hardened mortar (HM) without expanded vermiculite (EV) by an average of 8,3% for the HM with 10% EV, 14,7% for the HM with 20% EV and 24,2% for the HM with 30% EV. Compressive and flexural strength and static modulus of elasticity were investigated and the relationships between these properties were determined. The effect of the added amount of EV on: total porosity, air void content and capillary suction of HM according to SIA 262, Appendix A; capillary water absorption; gas permeability and air permeability; water permeability and internal freeze/thaw resistance up to 200 cycles was investigated and determined.
