| Research Abstract |
This study aims at developing the super high performance grout which has over 150N/mm^2 compressive strength. In order to produce the high performance grout, the mixing tests of the very low water cement ratio which is the rage from 12% to 20% were conducted. Through the test results, it was clarified that the super high strength grout could be produced and the strength was much affected by the mixing method. Moreover, the flow value was formulated by the W/C and the high water-reducing agent addition volume and the formulated equation was confirmed to be good correspondence with the tests results.
