摘要: A concrete admixture is provided to show a low hygroscopic and a compaction preventing effect using a maltodextrine having a bleeding and a rebound reducing function, to improve a construction property, to secure equal quality of the concrete and to improve a water-tightness and durability. An admixture mixes a maltodextrine in order to increase a viscosity and reduce a bleeding or a rebound. An antiseptic of 0.2 ~ 0.5 parts by weight is mixed into the maltodextrine of 1 parts by weight in order to prevent a decay of the mixed maltodextrine. The maltodextrine of 2 ~ 10 parts by weight is mixed when being mixed into a liquid phase and the maltodextrine of 1 ~ 5 parts by weight is mixed when being mixed into a gas phase.
