I have just finished casting 36 geopolymer mortar mix designs. Several variables were set in my work. Nanosilica replacement dosage (0, 2, 4% of slag weight), microsilica replacement dosage (0, 5, 7.5 and 10% of slag weight), chemical activator type (2 types), solution to base material ratio (2 levels).
I am asking about the best approaches to determine optimized mix designs for further tests.
In the first stage the compressive strength and flowability of mortars were evaluated.
best,
Setting time and rate of strength gain are also important for practical usage of geopolymers.
You can use the single factor experiments to examine the influence of various factors, finally get the optimal process parameters
Once you have made trial mixes and tested the required responses such as compressive test and other tests of interest ,you can then apply surface response methodology to optimize the mixes otherwise you will be forced to conduct several tests to come up with an"optimized mix"
