I would like to ask the following regarding the Structural Waterproof Concrete:
-What is the terminology for Waterproof Cpncrete (and where is stated)
-What are the most practical laboratory tests for waterproof concrete (among the numerous that exists)
-What are the values on these tests that prooves impermeability (and how these values are corelated with service-life of the construction).
Best regards

Spiros! Waterproof Concrete is a misnomer. It is concrete with low permeability. The permeability (typically water)of concrete can be reduced by refining its pore structure, using mineral admixtures like PFA, BFS, SF, MK and so on. The permeability of concrete is specified in the performance standard. It will be better to refer the national standard on the subject. http://www.drjdbapat.com

Dear Mr Bapat,
First of all thanks for the answer.It is well known that the use of supplementary materials (including correct packing)will close the pores.But ,in several national standards eg EN ,BS there rough and general references regarding that issue.
What is low permeability:lower than 20mm ,lower on 10mm on Water Depth in Penetration.
Regarding Capillary sorption is that test more reliable than WDP? and if yes with how much mm rise shall we be satisified?
How all these values are corelated with durability ?
Best regards

I saw your book and seems extremely interesting
