Water affecting concrete strength
(OP)
I have a project in which the concrete mix was done manually. The strength ahieved was 12N as opposed to 24N after 28days. Could the water used in the mix be the problem (Sulphur contamination)

Also give the concentration of the sulfur, if you know it.

When you say the concrete was batched manually, did the workers understand the proportions and were they supervised?
RE: Water affecting concrete strength
Based on the proportions (assuming volumetric) you noted, that would be a difficult mix to work with, assuming reasonable specific gravities of the aggregate (say 2.55 to 2.65). Your water demand would be high and your workability would be compromised. Further, your unit weight would be quite high for a suspended floor slab application. Hope the dead weight is correct in the design!!
