Mortar Mix Ratios
The volume of water required to reach the top of the sand is the amount missing from the measuring cylinder, and is equivalent to the void ratio in percentage terms. So, if 25ml of water is needed to reach the top surface of the sand, then the void ratio is 25 per cent.

concrete from mortar
I think you are confused here. Type S mortar definetly has portland cement in it. the biggest difference between type s mortar and concrete is the mortar has no stones and about 3x more sand. s-mortar only reaches a compressive strength of about 1800 psi, but thats laregely because more water is added, along with the lack of aggregate
