Due to the H<sub>2</sub>S from the sewage rot, the biochemical corrosion of the concrete can be ocurred. H<sub>2</sub>S gas is transferred into the SO<sub>4</sub><sup>-2</sup> ion in water. In this work the performance of the concrete mixed with antibacterial metals(Cu, Zn) and metal salts(Cu(NO<sub>3</sub>)<sub>2</sub>, Zn(NO<sub>3</sub>)<sub>2</sub>) is studied. The antibacterials of the concrete depend on the concentration of antibacterial agent. In after experiments, the relativity of the pH and the least concentration of the antibacterial agents must worked.

In this study, we research the concrete surface which is added the antibiotics(Cu, Zn, Cu(NO<sub>3</sub>)<sub>2</sub>, Zn(NO<sub>3</sub>)<sub>2</sub>. Antibiotic concrete have a resistance for the SO<sub>4</sub><sup>2-</sup> ion that is formed from the Thiobacillus thiooxidus on the culture ground. The result of this work is that the antibiotic concrete with Cu(NO<sub>3</sub>)<sub>2</sub> in the best effect to the antibacterial performance.

In this study, we research the concrete surface which is added the antibiotics(Cu, Zn, Cu(NO3)2, Zn(NO3)2. Antibiotic concrete have a resistance for the SO42-ion that is formed from the Thiobacillus thiooxidus on the culture ground. The result of this work is that the antibiotic concrete with Cu(NO3)2 in the best effect to the antibacterial performance.

The purpose of this paper is to investigate coefficient of chloride ion diffusivity of concrete mixed antibacterial agent. For this purpose, the experiments carried out with metals(Cu, Zn) and metal salts(Cu(NO<sub>3</sub>)<sub>2</sub>, Zn(NO<sub>3</sub>)<sub>2</sub>) as the antibacterial agent. The diffusion coefficient of the Cu(NO<sub>3</sub>)<sub>2</sub> is the smallest because of the smallest Ksp. The durability of the concrete antibacterial agent depend on the Ksp and watertighnee by the metal and metal ion solubility.

This study discussed about the pollution due to the ecosystem on the concrete surface. The concrete surface was decaied in the order of the higher humidity and the shading green algae. The black ecosystem substance as like Clisterium sp. etc. grow well at the a higher humid and shading place. The increment of ecosystem substance independed on the neutrality of concrete, that would be depended the environment of the concrete.

The wellbeing circumstance is the first objective of the recent human society. This paper discussed about the moisture absorption ability of the concrete material as like pearlite, vermiculite, pulp and rice straw. The most absorptive rice straw. In this paper, pearlite is used as an aggregate and the rice straw is used as a filler with small amounts.
