What is Lime Mortar?
Lime mortar is an effective adhesive used to bind building blocks together and fill the space between them.
Lime Mortar consists of lime, sand, water, and some distinctive herbals (Jute, Indian Gallnut, jaggery, Aloe Vera, Lady Finger, and Egg) in precise ratios.
The early Egyptians invented lime mortar 6000 years ago. They used this vital chemical to build pyramids and buildings as binder and plaster.
Lime mortar becomes solid when it sets, consequential in a rigid aggregate structure. After the invention of Portland cement, lime mortar usage declined rapidly.

Quick Lime Mortar
Lime mortar has been made by heating limestone (Calcium Carbonate) in high temperatures through Kiln, a process known as calcination, which results in Quick lime or calcium oxide.
CaCO₃ + Heat ―> CaO + CO₂
Hydrated Lime Mortar
Hydrated Lime Mortar (Calcium Hydroxide, or Ca[OH]₂) has been produced by reacting quick lime with adequate water to turn oxides into hydroxides.
It has seemed to powder composed of water and sand.
Hydraulic Lime Mortar
A unique form of limestone is used to make hydraulic lime mortar. The limestone is mixed with clay then headed in a kiln to high temperature. This operation eliminates too much of the moisture content from the lime and also produces mineral by-products known as silicates. The remaining limestone and silicates are combined to form hydraulic lime mortar. We can use hydraulic lime mortar in many applications where other lime mortar products would fail.
