dear concrete engineers,
what r the considerations, chemistry aspects, etc that i should be considering to ensure that the concrete obtained is water-tight. am already designing the structure for zero tensile stress using working stress method.
i have learnt that some components like C4A in concrete can play substantial role in making the concrete marine grade, water-tight, etc.
i hope you can throw more light on this and also provide suitable references, theories, links, etc..
thanks a ton

RE: for concrete engineers
Apart from designing for a maximum design surface crack width of say 2mm, there are further steps which can be taken. These include specifying an appropriate concrete mix design (which could include admixtures or silica fume), good construction joint detailing and if neccessary additional waterproofing measures such as a membrane.

whoops that was 0.2mm! (fortunately most board members seem to work in imperial and didn't notice the "small" error)
