| titleOfInvention | Admixture composition for shotcrete and high performance shotcrete composition using the same |
| abstract | The present invention relates to a functional admixture composition and a high performance shotcrete composition using the same, which is used for improving the strength, durability, etc. of shotcrete used as a temporary support material and a permanent support material to stabilize an excavation section immediately after excavation of a tunnel and underground space. Specifically, silica fume and metakaolin, which are mineral admixtures used in the past, to improve the performance of shotcrete, are pre-mixed with blast furnace slag powder, which is an industrial by-product, and admixture mainly made of gypsum, and coagulation characteristics, roughness, Disclosed is a high performance shotcrete composition which increases the long term durability as well as the mechanical properties such as compressive strength and flexural strength of shotcrete by using a cement mineral quickener having a low long-term strength decrease. In the present invention, in order to improve the long-term strength and durability of the shotcrete, the primary support for tunnels and underground spaces, 50 to 75% by weight of slag fine powder, 20 to 45% by weight of anhydrous gypsum, and 0.5 to 10 alkali activators It is characterized by including a% by weight, by applying a functional admixture composition for shotcrete and cement mineral-based fastener that may further comprise 0.01 ~ 0.5% by weight of a reducing agent is provided a high performance shotcrete that secures the roughness and construction safety . |
