Pile foundations are deep foundations used to transmit heavy loads of the superstructure to the soil below. Pile foundations are
normally used when soil below the structure has low bearing capacity and load on the foundation is high. Concreting in cast in
situ bored piles are done via trimie pipe underwater in the bore hole which is heavily reinforced. The paper deals with the
problems faced during concreting of pile foundations, and to find possible solution of main problems such as 1) Segregation of
concreting and 2) Jamming of trimie pipe by proper use of admixture by the case study and suggest the finalize mix for the
concrete used piles with good workability.
