“…A measure of the pozzolanic activity of the material is the difference in Ca(OH) 2 content in the initial solution and in the filtrate. Nino et al [ 106 ] have modified this method for their research. They used 300 mL of saturated calcium hydroxide solution at 20 °C, when the solubility of this compound in water is 1.65g/L.…”

Calcined clays are the only potential materials available in large quantities to meet the requirements of eco-efficient cement-based materials by reducing the clinker content in blended cements or reducing the cement content in concrete. More than 200 recent research papers on the idea of replacing Portland cement with large amounts of calcined clay are presented and discussed in detail. First, the fundamental information about the properties and structure of clay minerals is described. Then, the process of activation and hydration of clays is discussed, including the methods of pozzolanic activity assessment. Additionally, various testing methods of clays from different worldwide deposits are presented. The application of calcined clay in cement and concrete technology is then introduced. A separate chapter is devoted to lime calcined clay cement. Then an influence of calcined clay on durability of concrete is summarized. Finally, conclusions are formulated.

“…Ninov et al [35] found that the addition of 8% lime had an increase in strength during the first 6 months and after prolonged storage it can leads to a higher compressive strength. The reaction of lime with illite as the basic component of the clay was completed for about 3 to 4 months.…”

This paper studies the effectiveness of soil stabilizer on the problematic soil or soft soil. It is subjected to instability and massive primary and long term consolidation settlements when subjected to even moderate load increases. The purpose of this study is to review the techniques and materials that have been used in the soil stabilization by previous researchers. The performance of the soil stabilizer for stabilization by means of strength has been highlighted in this study. Unconfined compressive strength (UCS) test was carried out on stabilized soil samples and the results that obtained were discussed. The use of these techniques and materials may provide an inexpensive and advantageous construction process. As a conclusion, the strength of soil can be increased by using these materials and techniques in soil stabilization. This paper gives a comprehensive report on stabilization techniques and materials that have been used for soft soil and also discuss the potential of geopolymerization technology to be one of the new soil stabilization techniques.
