 note = {application/pdf, According to water purification function, micro-habitat creation effect of charcoal making it known to everyone. Application to insulations, sound-proof, and permeable pavement, etc, was expected using many properties due to porous concrete (PoC) which has void. So that PoC contains a lot of void, there are many cases that demanded strength of PoC are small. In this reason, substituting to pieces of charcoal into a part of coarse aggregates of PoC, the following suppositions were made, 1) Because strength of charcoal is small, charcoal does not contribute to strength of PoC. 2) When mixing proportion of PoC was decided, the substitution rate was calculated by volume percentage. Under these suppositions, substitution ratio of charcoal was changed, and trial manufacture of PoC in different substitution ratio and consideration for properties of hardened, strength of PoC.},
