In this study, we performed the mixture of materials having two environmental functions in concrete, which have recently been xpected to improve the environment. In this case, we mainly investigated the influence of fundamental properties, antioxidant and photocatalyst effect in concrete and summarized those results as follows.
(1) The bending and compressive strength of mortar mixed with Effective Micro-organisms (EM) ceramics increased more than those of plain. However, mortar mixed with EM liquid showed a tendency to generally decrease less than plain.
(2) We considered that the ratio of EM ceramics power was uniformly distributed in the concrete and thus this result in the strength of concrete. This result was actually proved by the measurement of pore volume and diameter.
(3) In an experimental result of the plant life of algae, algae began to stick the surface of concrete block mixed with EM materials 3 months later, and then it grew up conspicuously 6 months later. As a result, the concrete mixed with EM was proved to be effective in the plant life of algae.
(4) The workability was turned worst due to the decrease of flow value in concrete mixed with more than 6% of titanium dioxide.
(5) Additional experiment indicated that the strength of concrete mixed with more than 3% of titanium dioxide was rapidly decreased than that of plain. Therefore, the process of mixture was very significant in the usage of titanium dioxide.
(6) As a result of exposure test, cement paste mixed with titanium dioxide and mortar coating changed an environmental pollutant thinly by progress of time. However, the pollutant did not change with mixture difference of titanium dioxide.
