Ship bow supporting blocks
Ship bow supporting blocks
(OP)
Hi all,
Does anyone here know what kind/type of concrete used for the bow supporting block in dock yard?
If I'm going to use a 1m x 1m x 1m cube block,what type of concrete should I used?
Thanks all!

RE: Ship bow supporting blocks
You have already decided what size block you want, you surely know the weight of the vessel so you can work out the required compressive strength.
If you don't really have much of a clue, contact the quarry/mix supplier who will design a suitable mix for you.
You will also need to consider your requirement for reinforcement, which will be dependent on load and any requirements to control cracking (large cracks will allow water ingress and cause reinforcement corrosion). You may find pure mass concrete is suitable.

Thanks for your advise.
The blocks are used to support ships during works in dry dock,so, they are not submerged for any significant design. However, you've enlightened me about the issue. I will find out more about it.The blocks will only be in the water for a short period of time (say an hour or so).
I am new in this field,so, I really appreciate any useful reply here.
As far, the suggested load capacity of the block is 2500 metric tons (can consider it as static load). I'm not sure if pure mass concrete would be suitable?
Thanks in advance!

thanks for all your kind response!
though i've found a suitable design,grade of concrete and etc... the job has been cancelled. a big blow, but look at the bright side: i've learned a good experience and skills..
(i've even finished the design for the molds).
again, i thank you all for the supports/ infos given!
