[V-517] Influence of materials used and vibration compaction time on fullness and hardning characterrstics immediately demoldable concrete
Keywords:Immediate release concrete products, Volume rate of fine aggregate, Vibration compaction time, Fulfillment, Compressive strength, Surface quality
this experiment, among the production conditions, the effect of vibration compaction time on the fullness of the immediate release concrete and the characteristics after hardening was examined. As a result, the fullness and post-hardening characteristics differ depending on the type and physical properties of the fine aggregate used, and particularly when using a low-performance fine aggregate, it is confirmed that the filling rate and the compressive strength decrease. did. However, by setting an appropriate vibration compaction time, the filling property was improved even when using a fine aggregate with a low performance rate, and the target strength was satisfied.
