초록
In this study, evaluated ware the strength and durability of the vegetated water purification channel concrete to which recycled aggregates,hawang-toh and jute were applied. Box-Behnken method of response surface analysis in statistics was applied to the experimentaldesign. Experimental variables are as follows, recycled coarse aggregates, hawang-toh, blast-furnace slag and jute fiber. In the experiment,conducted were the tests of compressive strength, chloride ion penetration, abrasion resistance and impact resistance the replacementrate effects of the recycled aggregates, blast-furnace slag and hwang-toh on the performance of vegetated water purification channel concretewere analyzed by using the response surface analysis method on the basis of the experimental results. In addition, an optimummixing ratio of vegetated water purification channel concrete was determined by using the experimental results. The optimum mixingratio was determined to be in 10.0% recycled coarse aggregates, 60.0% blast-furnace slag, 10.1% hwang-toh and 0.16% jute fiber. The compressive strength, chloride ion penetration, abrasion rate, and impact number of fracture test results of the optimum mixingratio were 24.1 MPa, 999 coulombs, 10.30 g/mm3, and 20 number, respectively.
