Water Resistant Mortar

[Bubik]

Hi everyone

I have a question regarding water resistant mortar. . We have a concrete water tank for cement plant and the drawing specifies that the concrete wall on the inside is to be coated with 20mm water resistant mortar. What would be the proportions of cement\lime and sand for such mortar, what type of sand (i.e. course or fine) what type of lime ( hydraulic lime, non-hydraulic lime)??


Thanks

Sorry but the OP is too vague for me. Existing tank being repaired? New tank? Completely different situations, considerations, and designs.

No, the tank is new, it is not to be repaired. The drawings specify 20mm water resistant mortar to be applied on the concrete walls.

The drawings say that, but what specification are you working to? It is not good enough for a designer to just state an objective without detailing how it is to be achieved.

Thank you all for answering

The situation is that I am working on site. There is no more specifications regarding the mortar (only on a drawing) and there is no way to obtain any information from the designer ( it is another story why that is), so I am on my own. The only thing is that the tank's walls are constructed from concrete category S2...so it is my task to specify the mortar mix...

I think you should be looking at waterproofing treatments, not mortar, for a new concrete tank. Google crystalline concrete waterproofing and you will find a few manufacturers.

Crystalline concrete waterproofing looks very good. Thank you.
