This study investigates the evaluation of concrete due to the solid powder and leaving along time recycling water containing saccharic based stabilizing. Test results showed that increase of saccharic based stabilizing agent(SSA) inclined the fluidity of fresh concrete and declined the values with leaving along time progressive as well as indicating the similar tendency in terms of
air content. For the setting time, while specimens using only recycling water without SSA were not dramatically different from that of control concrete and it was accelerated according to prolonging leave alone time and increasing solid powder, it is confirmed that specimens using more SSA effectively delayed the initial and final setting time. It was demonstrated that the
compressive strength of concrete using SSA slightly and the content of solid powder increased, but it was decreased that leaving alone time was prolonged. Lately, It was also demonstrated that the length change by drying shrinkage was increased caused by prolonging leave alone time and increasing solid powder, but it was decreased according to more SSA.
