    abstract = {This research aims to investigate the capillary transport properties of concretes and natural stones
as to be used as an absorber plate material of solar distillation equipment. Macro scale photograph and porosity
test has been doneto determine the characteristics ofthe porous medias. In order to analyze the transport
properties, a sorptivity test was done in this study. Two different types of concrete was filled with Lumajang’s
sands and ferrous sands as the fine aggregates. Both types of concrete were then divided with two different
particle size which were 0.125 and 0.250 mm in diameter, respectively. A natural stone was used as a comparison
materials. The results taken from macro scale photographs showed that increasingsize of pore holes with the
larger aggregates particle’s size in both types of aggregates. The highest porosity was found in concrete with
ferrous sand with aggregate size of 0.250 mm specimen with a value of of 57.77%. The highest porosity was
gained in concrete with Lumajang sand with aggregate size of 0.250 mm specimen with the amount of 0.224%.
The largest volume of absorbed seawater and sorptivity coefficient was also obtained in concrete with
Lumajang sand with aggregate size of 0.250 with the value of 8.05 mL and 9.58&times;10<sup>&#150;5</sup> m/sec<sup>0.5</sup>, respectively.
However, concrete with ferrous sand with aggregate size of 0.250 has the highest mass flow rate with
the value of 3.25&times;10<sup>&#150;7</sup> kg/sec. The interconnectivity between the channels also has a significant role in mass
flow rate value which occurred in natural stone specimen.}
