| Abstract: | Concrete mix design procedures,cement,flyash,admixture,aggregate quality,test of mix design selection for RCC at Tongjiezi is described. Mixing, spreading, compacting of RCC, formation of structural joints,treatment of construction joints ,prevention of aggregate segregation and its handling are given. The instrumentation results are obtained in check of raw and processed materials,value Vc of construction quality, mixing time, mechanic index of RCC sampled from the outlet of batch mixer,spreading,compaction,degree of compaction. |
