The phrase "alkali strength" is correct and usable in written English.
It can be used in contexts related to chemistry or materials science, particularly when discussing the potency or concentration of alkali substances.
Example: "The alkali strength of the solution was measured to determine its effectiveness in neutralizing acids."
Alternatives: "alkaline concentration" or "alkali potency".
To indicate alkali strength, both alkali concentration in pretreatment solution (g alkali/g pretreatment liquor or g alkali/L pretreatment liquor) and alkali loading based on biomass solids (g alkali/g dry biomass) have been widely used.
A literature survey also indicates that both alkali concentration in pretreatment solution (g alkali/g pretreatment liquor or g alkali/L pretreatment liquor) and alkali loading based on biomass solids (g alkali/g dry biomass) have been widely used as indicators of alkali strength.
Although alkali concentration (g NaOH/g pretreatment liquid) has been widely used as an indication of alkali strength in the literature, the experimental results suggest that alkali loading based on total solids (g NaOH/g dry biomass) governs the pretreatment efficiency.
This study focused on production of high strength alkali activated binder by alkali activation of binary mix of palm oil fuel ash (POFA) and ground granulated blast furnace slag (GGBS) at ambient temperature.
These intensity variations indicate variations in the Q n distribution as a function of the alkali ionic radius/field strength, similar to the conclusions drawn from previous 29Si NMR (e.g., Maekawa et al. 1991) and Raman (e.g., Matson et al. 1983; Mysen 1990) spectra of binary alkali silicate glasses.
The properties that were studied include setting time, workability, compressive and flexural strength, alkali-silica reaction, and micro-structure of mortar.
Although they possess early high strength, alkali-activated mortars based on mine waste mud calcined with sodium carbonate present a high amount of sodium efflorescences after water immersion that maybe due to an ineffective chemical combination.
Composite binders of urban waste glass/blastfurnace slag activated by NaOH and NaOH/Na2CO3 were studied using statistical methods (Taguchi); the factors were: %glass, curing temperature, %Na2O and ratio of alkalis; the compressive strength was the response variable.
While the strength of alkali activated copper slag mortars increased dramatically both within 200 °C and after 800 °C.
In this laboratory work, high compressive and flexural tensile strength of alkali activated fly ash geopolymer mortars were presented.
The results showed that the tensile strength of alkali treated bamboo fiber was comparable with those of common strong natural fibers such as hemp and flax fibers.
