Another study dealt with the release and transformation of alkali metal species co-coustion of coal and S-rich wheat straw. It was found that the releasing processes of Cl and alkali metals were consistent at high temperatures, and it was apparent that there were chlorides formed with the emission of alkali metals (Li et al. 2014).

Why do alkali metals are soft and can be cut with help of …

Alkali metals have large atomic size with only one valence electron. Terefore, they have weak metallic bonding between the atoms. Due to the presence of weak metallic bonding alkali metals are soft and can be cut with a knife.

Interaction of Magnesia with Limestone-Metakaolin …

Alkali-activated slag upon dissolution forms mainly calcium silie hydrate incorporating some aluminum (C(-A)-S-H), hydrotalcite-like phases, stratlingite, and amorphous geopolymer gel []. These systems suffer from significant autogenous and drying shrinkage and microcracking of the binder matrix.

Influence of Pb Dosage on Immobilization Characteristics …

Alkali-activated matrices are suitable materials for the immobilization of hazardous materials such as heavy metals. This paper is focused on the comparison of immobilization characteristics of various inorganic composite materials based on blast furnace slag and on the influence of various dosages of the heavy metal Pb on the mechanical properties and fixation ability of prepared matrices

Materials | Free Full-Text | Mitigating the Drying …

The alkali metal ions in the reaction solution entered the C–A–S–H gel, changed structures and led to collapse and redistributed upon drying [11,12]. High drying shrinkage and high autogenous shrinkage deformation could seriously influence the properties and durability of AAS, which limited the usage and promotion of AAS.
