Sand (SiO2) is a network covalent solid. It's considered to be extremely strong with relatively high melting points (>1550'C). It is made by atoms making multiple bonds with other atoms in the "network". To compare, another example of a network covalent solid is diamonds.
Shear strength of fine sand is determined by the angularity of the sand particles, the grading of the sand. These two features governs the critical state shear strength parameters of the sand. Density, however, dictates the peak shear strength of the sand. i.e. the denser the sand, the higher the peak shear strength. But the critical shear strength remain the same. The denser the sand, the lower the void ratio. Shear strength of fine sand is determined by the angularity of the sand particles, the grading of the sand.

Require strength for Plaster?
mortar are mixing by sand & cement and concrete is mixing by cement, sand & stone
Hai, i want to know the difference in strength of cocrete with silica sand as compared to normal sand, can somebody help me?
The water helps bond the sand
The sand (ballast) provides strength, hardness, and durability. The cement binds the sand/gravel together.
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.

Soil has better stability because it can be wet and have better strength than sand...
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.
The impurities like clay and silt in sand can reduce the strength of concrete by weakening the bond between the cement and aggregates. This can lead to an increase in voids in the concrete mixture, reducing its structural integrity and overall durability. It is important to use clean and well-graded sand to maintain the desired strength of the concrete.
there will not be enough strength
