Dear all,
I am facing problem in casting a web opening beam. The opening of the beam has been designed with some extra reinforcement around the opening due to which there is some congestion of reinforcement. So i am facing very difficulty in performing the casting from the top fiber of the beam (Vertical direction of the beam) as i am using normal concrete of M25. As if the casting is done from the top the concrete may not be homogeneous below the opening. In order to have a homogeneous distribution of concrete i have a second thought to cast the beam from the transverse direction as that will lead to a better compaction of concrete and an even distribution inside the stirrups..
I wanted to know if the casting is done from the transverse direction will it simulate the same behaviour like that of a beam which is always casted from the top.
Please help me with your sugesstion.....
You can cast the beam layer by layer from bottom to top i.e. 1st bottom layer of the opening, then opening layer after proper compaction of 1st layer then the top layer. Use pressure and jolting for better compaction.
Transverse casting will not be preferable.
