Description	Bulk density, matrix density, open porosity, pore size distribution, compressive strength, resistance against de-icing salts, water absorption coefficient, water vapor diffusion resistance factor, adsorption and desorption isotherms, thermal conductivity, and specific heat capacity of high performance concrete containing up to 40% of natural zeolite as Portland cement replacement were measured and compared with reference Portland cement concrete. Experimental results show that the replacement of Portland cement by natural zeolite in the amount of 10% by mass can be considered the most suitable option among the studied mixes. At this replacement level, the increase in open porosity, thus in liquid water transport properties is within reasonable limits, the mix retains its high performance character as for the compressive strength, the water vapor transport parameters, and thermal parameters are acceptable. The poor resistance against de-icing salts presents, however, a limitation even for the mix with Bulk density, matrix density, open porosity, pore size distribution, compressive strength, resistance against de-icing salts, water absorption coefficient, water vapor diffusion resistance factor, adsorption and desorption isotherms, thermal conductivity, and specific heat capacity of high performance concrete containing up to 40% of natural zeolite as Portland cement replacement were measured and compared with reference Portland cement concrete.
