Concrete mix ratio is a relative proportioning of cement, sand, aggregate and other materials needed to prepare different grades of concrete. For example, the prescribed Nominal concrete mix ratio of M20 concrete is 1:1.5:3, hence for every 1 part of cement, 1.5 parts of sand and 3 parts of aggregate, in volume, is needed to prepare M20 grade concrete.

Effects of Sand Quality on Compressive Strength of Concrete: A
With regard to compressive strength, 38% of the concrete cubes made from sand with varying sand impurities failed to meet the design strength of 25 Mpa at the age of 28 days. A combined regression equation of with R2 = 0.444 was generated predicting compressive strength varying levels of silt and clay impurities (SCI), and organic impurities (ORG) in sand.
Sand is a naturally occurring granular material composed of finely divided rock and mineral particles. It is defined by size, being finer than gravel and coarser than silt. Sand is a vital ingredient of concrete as a fine aggregate. Although the sand is an inert material in the concrete mix, its

2020/9/27Sand Tough Spots. sand continuously for about 30-60 seconds depending on what type of concrete surface you are working on. For a countertop, just sand for about 45 seconds, then clean the surface and check it out. If you sanded it effectively, you should see a bit of exposed aggregate on your surface.
In this definition, the volume is that contain both the sand and the voids between sand particles. The approximate bulk density of sand that is commonly used in normal-weight concrete is between 1520-1680 kg/m3 (95-105 lb/ft3)  Here, Standard test method for determining the bulk density of sand is given in ASTM C 29 (AASHTO T 19).

This paste is also called as concrete. The strength of this concrete mix is determined by the proportion on which these cement, sand, stones or aggregates are mixed. There are various grades of concrete available in the market based on these ratios. Some of them are: M10, M20, M30, M35, etc. So, what really does M10 or M20 mean or represent.
