The phrase "activating solution" is correct and usable in written English.
It can be used in contexts where a solution is intended to initiate or trigger a process or reaction, often in scientific or technical discussions.
Example: "The activating solution was added to the mixture to start the chemical reaction."
Alternatives: "initiating solution" or "triggering solution".
This paper evaluates the effect of fly ash and slag proportions and the type of activating solution on shrinkage and strength development of alkali-activated binary fly ash-slag mixtures (mortar and paste), cured at room temperature.
Initial setting times ranges from 38 to 263 min depending on the activating solution composition, and workability time decreases for increasing %Na2O.
The influence of the activating solution composition on the stability and thermo-mechanical properties of geopolymers made from a Cameroonian volcanic ash is investigated.
The volume ratio of powder to alkaline activating solution (Vp/Vaas) was chosen as an input signal, while flow value and flexural and compressive strengths were considered as output values.
Results show that the corrosion densities of Mg Zr alloy in OPC solution are one order of magnitude more important than in activating solution of Na-geopolymer and sodium fluoride addition decreases corrosion densities in OPC interstitial solution.
Activating solution (pCa 4.33) contained all the ingredients of relaxing solution (pCa 10).
The solution exchange protocol consisted of 3 phases with a duration of 2 s each and a flow rate of 250 µl/s: a flow of nonactivating solution (NA) followed by activating solution (A) followed by nonactivating solution (NA).
The results indicated that the compressive strength of geopolymer binder is primarily dependent upon the nature of source materials for a selected alkali-activating solution.
For force (Po) and maximum shortening velocity (Vo), determinations fibres were first transferred to pre-activating solution for at least 2 min and then maximally activated (pCa 4.45) for about 40 60 s.
Four types of mortars were manufactured, and the only difference between them was the alkaline-activating solution.
An alkali-activating solution plays an important role in dissolving Si and Al atoms to form geopolymer precursors and aluminosilicate material.
