An isothermal test offers information at each temperature, such as the length of the incubation, the order of the reactions, and the constant conversion rate. The calculation meets DIN 53529’s requirements. Then, using the incubation time and the conversion rate constant at least three distinct temperatures, it is possible to determine the activation energies of the incubation and the conversion. Both in the production process and for estimating the heating time for the test specimen, these factors are essential.
An aluminosilicate source must be activated by an alkaline solution as part of the geopolymerization process. Rheology follows its kinetics. From the initial stage, geopolymer paste, until the gel point with the construction of a geopolymer network, oscillatory rheological measurements are used to track the storage modulus (G′) and loss modulus (G′′). The findings indicate that a rise in temperature reduces reaction time. The Reaction Time-Temperature Superposition (RTTS) principle is introduced to forecast this phenomenon. Additionally, it is noted that altering and adjusting the reaction time is possible when utilizing metakaolin mixes with various reactivities. The creation of the geopolymer network is determined to require a certain weight percentage of reactive metakaolin.
