concrete is heterogeneous mixture. Ingredients in concrete are cement, sand, aggregates,and water. These are mixed based on mix design.
Concrete is made up of three main ingredients - water, Portland cement, and aggregates. To dissolve it, you can use hydrofluoric acid which is quite dangerous to use, or products called Ascarlite or Cemix.
The primary nutrients are N-P-K. Nitrogen, Phosphorus, and Potassium (Kalium). Iron and Chloride are also minor nutrients.
When the solutes (soluble ingredients) mix together with the solvents (insoluble ingredients) to form a mixture that is of the same consistancy throughout. Eg - When making concrete the cement should be fully mixed, making a homogenous mixture so as to maximise strength. ------------------------ You get a solution.
red blood cells, white blood cells, platelets, plasma.....put all these ingredients together and you have blood - an essential part of the circulatory system.

Ballast, sand and cement (+water).
The designers calculate the potential effects of cracking on the concrete columns.
concrete ingredients are directly feed in to the mixture plant and mixing done by means of machine. And it is pumped by means of concrete pump and placed in the site.
texture
Its the process of selecting suitable ingredients of concrete and determining their relative amounts with the objective of producing a concrete of the required, strength, durability, and workability as economically as possible, is termed the concrete mix design.
