Reaction mechanism of solid lime (calcium oxide).

Introducing "immediate effects" and "delayed effects"! Carbonation improves strength and durability!

Solid lime (calcium oxide) reacts with water in the soil when added, transforming into slaked lime. At that time, it absorbs a large amount of water and simultaneously generates heat, causing moisture to evaporate. Due to this hydration and evaporation, approximately 80% of the product's weight is lost as water, resulting in a significant decrease in the soil's moisture content. During this hydration reaction, calcium ions generated by dissolution are adsorbed onto clay particles, causing the clay particles to exhibit aggregation, leading to soil granulation. This is referred to as an ion exchange reaction, and this action occurs relatively quickly, affecting the initial strength increase and changes in consistency. [Immediate Effects] - Reacts with water in the soil to become slaked lime when added - Absorbs a large amount of water and simultaneously generates heat, causing moisture to evaporate - A significant decrease in the soil's moisture content due to the loss of approximately 80% of its weight in water - Clay particles exhibit aggregation, leading to soil granulation (ion exchange reaction) - Affects the initial strength increase and changes in consistency *For more details, please refer to the PDF document or feel free to contact us.
