Simple limestone, crushed can be used with sand as a mortar, but it is VERY slow in reacting after it has (moisture) set.
If you use limestone from which the water of crystallization has been baked out = quicklime, then the reaction will take place more quickly, as the quicklime gradually forms new crystal bonds, including some with the sand (=silica).
Portland cement has a similar but more powerful reaction, except VERY finely divided (=highly reactive) silica is added in the form of diatomaceous earth. Gypsum is also added to the mix and all is baked together.
The reactions formed are complex calcium silicates and sulphates and carbonates, and take many years for their final form. This is greatly enhanced, by keeping the concrete wet covered for at least 7 days, and even 28 days is often used where maximum strength is needed.
This is accomplished, by allowing the new crystals to fully form, which they will not do if the water is allowed to dry out. Silica has a high propensity to crystallize.

Is limestone same as lime?
Really they are different. Because 'mortar' which is usually called refers to the mixture of cement, sand and water. Whereas, lime mortar refers to the mixture of lime, sand and water. But both are used as a binding material.
Uses of limestone?
After being quarried it can be "roasted" in a revolving cylindrical "oven" to produce cement. Cement is in concrete and mortar, so the limestone has helped the construction of buildings and bridges. Indeed during the last World War there were even boats made from concrete. Limestone itself can be used as the foundation for road construction, and, like other types of stone, is used to construct stone buildings and stone walls. Lime and limestone are also used in many industrial and chemical processes.

Which mineral is used to make cement and mortar?
Limestone is the primary mineral used to make cement and mortar. It is primarily composed of calcium carbonate, which when heated in a kiln produces lime (calcium oxide) that is a key ingredient in cement and mortar production.
