Difference Between M sand and River sand. Concrete with m sand has very poor permeability as compared to river sand. But when river sand is used in concrete the permeability of concrete is less poor as compared to river sand. It has more water absorption 2 to 4 %. Whereas water absorption of river sand is less 1.5 to 3%.

Sand is often used as part of the base and helps provide strength and stability. When selecting sand for patios and paths, it is important to consider particle size and composition, as different types of sand can provide different performance levels. Course sand, such as washed river sand, is often used for patios and paths.

Figure 3a, b show the graphical pattern of the chemical composition of river sand and steel slag. The raw data peaks are matched with the data available, and the quantity in percentage is shown in Table 4. The graph pattern of steel slag is smoother compared to that of river sand due to amorphous nature of steel slag.

The chemical composition of sand can have a big impact on its usability. For example, the presence of too much silica can make sand difficult to work with, as it can cause Silicosis. On the other hand, the presence of minerals like apatite and feldspar can make the sand more usable for certain applications. It is important for civil engineers ...
