My husband is a plasterer by trade. Lime helps the plaster to cure, reduces the amount of spider cracks and helps it stick better, I believe.

It is an important cement ingredient and its proportion must be carefully maintained. It occupies the percentage of 60-67%. The lime in excess makes the cement unsound and causes the cement to expand and disintegrate.

Lime is a versatile building material that is commonly used as a binding agent for mortar, plaster, and stucco. It is also utilized in the production of lime concrete and as an ingredient in the manufacturing of various construction materials like bricks, tiles, and blocks.
It depends on the age of the mortar. Today's mortar is made from sand, Portland cement and water. In very cold weather a plasticiser is added. Prior to about 1900 mortar was made from sand, lime and horse-hair.
Cement is just the powder used to make mortar and concrete. Mortar has sand in it.

First you need to recognize that "plaster" is not a singularly defined material; it is a family of quite different materials that harden by different mechanisms. The three most common plasters are (1) Plaster of Paris, (2) Lime Plaster, and (3) Cement Plaster.(1) Plaster of Paris is CaSO4.H2O, a partially-dehydrated form of Gypsum, which is a hydrated Calcium Sulfate crystal CaSO4.2H2O. When Plaster of Paris is mixed with water, it re-hydrates and turns back into Gypsum, which then hardens into a material similar to mortar or concrete but considerably softer. Water is the material that makes Plaster of Paris harden.(2) Limestone When exposed to atmosphere the Calcium hydroxide turns back to limestone, causing the plaster to set.(3) Cement Plaster is a mixture of Portland Cement powder, sand or other filler, water, and either Plaster of Paris or Lime Plaster. Due to the great variety of minerals that makeup Portland Cement and Cement Plaster, the hardening is a complex process that cannot be ascribed to the action of any one of the ingredients.
There are a couple types of plaster that can be used for interior walls. One form of plaster is lime plaster; it is made up of calcium hydroxide and sand. Cement plastic is a mixture of sand, water, portland cement, and suitable plaster.

Plaster typically consists of gypsum, water, and sometimes additives like lime or cement. These components are mixed together to create a paste that can be spread onto surfaces to create a smooth finish once dried.
Determination of Free Lime in Clinker and Cement?
The cement add carbon dioxide because lime stone is added in it. To make this Hard we use lime. Lime gives out co2 in the reaction between air and concrete. so this how co2 comes out of cement. BY SWETHAN PETER FROM RYAN GLOBAL SCHOOL GRADE 8
cement
The lime content that is found in cement causes cement to heat.
Lime-cement mortar is also known as composition or "compo" mortar.
