Sand and gravel can be used together in aquariums, but if the gravel is put down first it will end up on top as the sand gradually settles to the bottom.

The flow properties of a suspension of sand in water will be controlled by how much sand is added and will change over time as the sand sediments out. Koos and Willenbacher (p. [897][1]; see the Perspective by [Butt][2] ) studied the agglomeration of particles suspended in a liquid under the influence of a small amount of a secondary, immiscible liquid.

Concrete mix ratio of 1:3:3 – On mixing 1 part cement, 3 parts sand with 3 parts aggregate produces concrete with a compressive strength of 3000 psi.. On mixing water with the three ingredients, a paste is formed that binds them together till the concrete mix gets hardened.The strength concrete is inversely proportional to the water/cement ratio.
