고강도콘크리트의 제물성 향상을 위한 연구

To improve the qualities of high strength mortar and concrete with high range water reducing admixture, silica fume and gypsum is applied. The flow loss of mortar is reduced and the compressive strength of mortar and concrete is improved by silica fume. And the silica fume is effective for decreasing the temperature of high strength concrete. In addition to, the strength of high strength concrete is more improved by the gypsum.
