“…The reason for this rise in compressive strength was that the geopolymer melted at a higher temperature due to the low Na + diffusion coefficient at high temperatures. Meanwhile, the study by Hsieh et al [72] concluded that the structure became denser as the temperature rose, which was related to the potassium found in the alkali activator being dehydrated.…”

Globally, there is an increasing need for ceramic materials that have a variety of applications in the environment, for precision tools, and for the biomedical, electronics, and environmental industries. However, in order to obtain remarkable mechanical qualities, ceramics have to be manufactured at a high temperature of up to 1600 °C over a long heating period. Furthermore, the conventional approach presents issues with agglomeration, irregular grain growth, and furnace pollution. Many researchers have developed an interest in using geopolymer to produce ceramic materials, focusing on improving the performances of geopolymer ceramics. In addition to helping to lower the sintering temperature, it also improves the strength and other properties of the ceramics. Geopolymer is a product of polymerization involving aluminosilicate sources such as fly ash, metakaolin, kaolin, and slag through activation using an alkaline solution. The sources of the raw materials, the ratio of the alkaline solution, the sintering time, the calcining temperature, the mixing time, and the curing time may have significant impacts on the qualities. Therefore, this review aims to study the effects of sintering mechanisms on the crystallization of geopolymer ceramics, concerning the strength achieved. A future research opportunity is also presented in this review.

“…Researchers have paid much attention to the optimization of geopolymer binders and concrete compositions [13][14][15], the study of the physical and mechanical properties of concrete [16][17][18][19][20] and structures based on them [21], as well as various uses of the technology of geopolymer binders to obtain new materials [22]. At the same time, the authors touch upon topical environmental issues in the production of geopolymer concrete [23,24] and the problems of predicting the mechanical characteristics of finished materials, products, and structures using artificial-intelligence technology [25].…”

Improving the efficiency and quality of construction mainly depends on the cost of building materials, which is about 55–65% of total capital-construction costs. The study aimed to obtain geopolymer fine-grained concrete with improved quality characteristics that meet the construction field’s sustainable development criteria and that have environmental friendliness, economic efficiency, and advantages over competing analogues. The dependences of strength characteristics on various compositions of geopolymer concrete were obtained. It was found that the most effective activator is a composition of NaOH and Na2SiO3 with a ratio of 1:2. The increase in the indicators of the obtained geopolymer concrete from the developed composition (4A) in relation to the base control (1X) was 17% in terms of compressive strength and 24% in tensile strength in bending. Polynomial equations were obtained showing the dependence of the change in the strength characteristics of geopolymer concrete on the individual influence of each of the activators. A significant effect of the composition of the alkaline activator on the strength characteristics of geopolymer fine-grained concrete was noted. The optimal temperature range of heat treatment of geopolymer concrete samples, contributing to the positive kinetics of compressive strength gain at the age of 28 days, was determined. The main technological and recipe parameters for obtaining geopolymers with the desired properties, which meet the ecology requirements and are efficient from the point of view of economics, were determined.

“…Lee and colleagues assessed the preparation of potassium-based geopolymers (KGL) into leucite ceramics and tested their structure and mechanical properties [ 16 ]. By taking into consideration alkaline solution ratio, calcining temperature (T), and sintering, mixing, and curing time, they tested the prepared specimens to better understand the geopolymerization reactions and the characteristics of the KGL network.…”
