M Sand Vs River Sand (Natural Sand)
Higher concrete strength compared to river sand used for concreting. Lesser concrete compared to M Sand. Silt Content. Zero silt. Minimum permissible silt content is 3%. Anything more than 3% is harmful to the concrete durability. We can expect 5 - 20% slit content in medium quality river sand. Over Sized Materials.

Concrete Mix Ratio | What Is Concrete Mix Ratio | Types of ...
What Is Concrete Mix Ratio? Making concrete, it is important to use the correct concrete mixing ratios to produce a tough, long life, durable concrete mix. To make concrete, four basic materials you need: Cement, sand, aggregate, water, and add-mixture. This concrete mix ratio of aggregate to sand to cement is an important factor in determining the compressive strength of the concrete mixture.
