Abstract |
In this study, the workability, compressive strength, chloride resistance, and drying shrinkage of concrete mixed with functional materials such as copper powder, phytoncide, and zeolite were evaluated to examine their effects on fundamental properties and durability. The test results showed that the slump and air content tended to be similar to or slightly lower than those of the reference mix, depending on the type of functional material.
Compressive strength and chloride resistance generally increased or remained similar compared to the reference mix. Although drying shrinkage either increased or decreased depending on the mixture, the overall variation was relatively small. Zeolite was found to reduce workability by absorbing mixing water and decreasing the effective water-to-cement ratio, while enhancing compressive strength and chloride resistance through pozzolanic reactions.
Among the functional materials evaluated, zeolite had the most significant influence on the properties of concrete. In contrast, copper powder and phytoncide were found to have minimal effect.
