A comparison of two methods of placing water concrete, the tremie method and 8 under- rop-bot-tom bucket method. The strengths of the tremie concrete are compared with similar concrete deposited in air under standard control conditions. The effect of qradinq of aggregates, quality of cement and workability on subaqueous concrete was also studied. The strengths obtained from sub-aqueous concrete were lower than the strengths obtained from the same concrete not deposited under water. On an average, tremie concrete was I7 percent stronger than concrete placed with a drop-bottom bucket.
