| Abstract |
Recently ultra high strength concrete is actively being developed and studied, and this trend is explained with the following effects. Technological effects expected from the application of ultra high strength concrete include the reduction of section, the decrease of structure mass and the improvement of workability. However, the high strength concrete has the problems such high brittleness and low ductility. Belite cement has properities like low heat of hydration, excellent long term strength, and durablity without admixture. so, Belite cement is suitable for mass structure which is needed high strenghth, high fluidity and heat property. The basic experiment was performed with changing water binder ratio, unit quantity, and additive substitution rate. this study is an experiment about using the miscible materials affects what happens to the longitudinal physical property. The objective of this study is to examine the suitability of mixture ratio through experiment of basic physical properties and provide materials for the field application of ultra high strength concrete. |
