This study intends to identify basic properties of porous concrete mixed with cooper slag. The specimens were made with porous concrete containing cooper slag with various mixing ratio(10, 20, 30, 50%). Other specimens were made with ordinary porous concrete and porous concrete containing river fine aggregate and crush fine aggregate. W/B and target void ratio of all specimens were fixed 0.25 and 20% relatively. The experiment were measured by compressive strength, total and continuous void ratio, and coefficient of permeability. The results of the experiment are as follow.
When mixing ratio of cooper slag in porous concrete was increased from 0% to 50%, it was observed that compressive strength of porous concrete was increased from 14% to 34%. Observing of total void ratio and continuous void ratio, all specimens showed that as mixing rates of fine aggregate were increased as the porosity were decreased.
The results of coefficient of permeability was met up to 50% of mixing ratio specimens which is the standard of Japan Concrete Institute-Eco Concrete Committee(0.1cm/sec) but if more than 20% of specimens think about total void ratio and continuous void ratio.
