Once all ingredients are thoroughly wet (no "streaks" of dry cement) and the "slump" is correct, it is fully mixed.
Lean mix concrete is used for substructures like foundations,piles,etc.,Ready mix concrete is used for superstructures and also for mass construction.Generally, quality of ready mix concrete is good when compared to the lean mix concrete.Workability of lean mix concrete is high when compared to RMC.
Water is added to concrete mux because without it, the mix could not stay moist long enough for it to get spread and leveled. <><><> Adding water starts a chemical reaction when the concrete CURES (not dries) into a solid mass. No water, your mix sits there as a dusty mix of sand, aggregate, and Portland Cement. Too much water, and your finished concrete will be of low strength.
To properly mix and pour concrete for a durable and long-lasting project, follow these tips: Use the correct ratio of water to concrete mix as per the instructions on the bag. Mix the concrete thoroughly to ensure uniform consistency. Pour the concrete evenly and avoid overworking it to prevent air pockets. Use a trowel to smooth the surface and remove any excess water. Allow the concrete to cure properly by keeping it moist and protected from extreme temperatures.
The best type of concrete mix to use for setting fence posts securely in place is a high-strength concrete mix with a minimum compressive strength of 3,000 psi. This type of mix will provide the necessary durability and stability for the fence posts to withstand external forces and remain in place for a long time.
Concrete mix is made from (sharp)sand, cement, aggregate and water. The ratios depent on the usage
The best materials for creating a durable and long-lasting concrete fence post are high-quality concrete mix, steel reinforcement bars, and proper curing methods.

Concrete :- a mix of cement, sand, water, and gravel. Mortar :- a mix of cement, sand, and water

The strength of concrete depends on the mix used to make it- ratio of cement, sand, gravel and water. If the mix does not produce a concrete that is strong enough, the concrete will break.
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.
