08/05/2014  The various methods of hand compaction are as given below. 1. Rodding. It is a method of poking with 2m long, 16 mm dia rod at sharp corners and edges. The thickness of layers for rodding should be 15 to 20 cm. 2. Ramming. It is generally used for compaction on ground in plain concrete. It is not used either in RCC or on upper floors.

COMPACTION FACTOR TEST Cement concrete to be tested is placed in the hopper A and its bottom released.The concrete falling in hopper B achieves some compaction. The bottom of hopper B is now released so that concrete now falls in cylinder C. surplus concrete is removed from the top of cylinder. Concrete in the cylinder is now weighed. Let this weight beW1 . After cleaning the cylinder it is ...

self compacting concrete 1. By the early 1990's, Japan has developed and used SCC. Self compacted concrete is highly engineered concrete with much higher fluidity without segregation and is capable of filling every corner of formwork under its self weight . Thus SCC eliminates the vibration for the compaction of concrete without affecting its ...

17/02/2016  Compaction of concrete is one of the important site operations that together enable the fresh concrete to reach its potential design strength, density and low permeability. Properly carried out it ensures that concrete fully surrounds and protects the reinforcement, tendons and cast-in inserts. It also has a direct impact on achieving the specified surface finish. Compaction is the process ...
