Require strength for Plaster?
The sand and stone adds a binding quality to the cement making the concrete or plaster stronger than pure cement.
You can plaster a wall with Portland cement and fine sand mixture. Polymers are plastics and I've found nothing on using them in a mixture to plaster a wall.
mortar are mixing by sand & cement and concrete is mixing by cement, sand & stone
The ratio of sand to cement significantly influences the strength of concrete. A higher sand-to-cement ratio can lead to a weaker mix because it reduces the amount of cement available to bind the aggregates together, resulting in lower compressive strength. Conversely, a lower sand-to-cement ratio typically increases strength, as there is more cement to create a dense, cohesive matrix. However, an excessively low ratio can also negatively impact workability and lead to cracking, highlighting the need for a balanced mix.
Cement is hydrated limestone. Concrete is cement, stone and sand. Sometimes fiberglass fibers are added to increase strength.

The formula for cement plaster typically involves mixing cement, sand, and water in specific ratios. A common ratio is 1 part cement to 3-4 parts sand, with the addition of water to achieve the desired consistency for application. It's important to follow manufacturer recommendations for the specific type of cement being used.
The ideal ratio for a cement-sand mix to achieve optimal strength in a construction project is typically 1 part cement to 3 parts sand.
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.
The recommended sand to cement ratio for optimal strength in a concrete mix is typically 2:1. This means using two parts sand for every one part of cement.
To determine the number of cement bags needed for 20mm thick plaster, first calculate the total volume of plaster required. For example, if you need to cover 1 square meter, the volume would be 0.02 cubic meters (20mm = 0.02m). Assuming a typical mix ratio of 1:6 (cement to sand), you would need about 0.033 cubic meters of cement, which is approximately one 50 kg bag of cement per 1.5 square meters of plaster at that thickness. Therefore, for 1 square meter, you would need approximately 0.67 bags of cement.

You need a clean sharp washed riversand cement and lime.
A thickness of 10-12mm is used for the plastering and a mix ratio of (1:4) cement and fine sand is used well finished with a wooden float.
