What is the solubility characteristic of sand lime mortar?

Sand lime mortar is primarily made from sand, lime, and water, and it serves as a binding agent in various masonry applications. The solubility characteristic of sand lime mortar is best described as not soluble in solvents or oils. However, when discussing its interaction with water, it is important to recognize that while the components may react with water during application and curing, the final hardened mortar does not dissolve in water. Instead, it gains strength over time through a chemical process known as carbonation, where the lime reacts with carbon dioxide in the air.

When considering the answer that identifies sand lime mortar as water soluble, it is important to clarify that while the raw materials interact with water during the mixing and curing phase, the hardened mortar itself does not dissolve in water. Instead, it remains intact and provides structural integrity. This is a crucial distinction, as it highlights the mortar's durability and longevity when used in construction.
