| Abstract |
Because this experiment uses flyash that is by-product of thermoelectric power plant, and the practical use allows purpose can augment the mixing rate and concrete early compressive strength presents application way of subsequentness various building through method that can define. This research for this is presented new addition method applying flyash addition method 4 that present in RILEM. The concrete improve of the strength in addition method to alternate one part of cup aggregate amount by flyash among 4 addition method thus, appeared by is good manegement to long-term compressive strength, weight decrease, thermal insulation ability improvement, and medicative thing of drying shrinkage improvement and so on.Therefore, this study is expand the flyash mixing rate to 40% as cement weight such new match plan, and diversified research for concrete durability promotion is judged should be continued because controlling America briquet small quantity reduction method for liquidity improvement and mixed soul topic amount furthermore. |
