Hi everyone!
I´ve a problem!in order to make some test for a special mateial I have to find an alkaline solution of ph
-9
-11
-13,7
at 40°C temperature.
We need to find the composition of this solution to simulate the alkaline water inside the concreate pore and so it has to be composed with 3 elements:
-NaOH
-KOH
-Ca(OH)2
the ratio of these element must be the following:
if NaOH =1 then KOH= 2,64 and Ca(OH)=0,76.
THANKS SO MUCH!
