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.
a blinding concrete is a thin layer of lean concrete
Main function of the lean concrete is to provide the uniform surface to the foundation concrete and to prevent the direct contact of foundation concrete from the soil. Lean concrete is used under the foundations.
A plain concrete with a large ratio aggregate to cement than structural concrete. It is used for filling and not structural duties
Standards normally are 4 inch AA
PCC in construction refers to Plain Cement Concrete, which is used as a preparatory base for laying RCC footing. Though PCC is also concrete, this is lean in nature, the ratio being 1:4:8. The compressive strength achieved with this mix is normally 7.5kN/sq.mm.
Blind Concrete
I think it is twice the cost of ready mix concrete?
Mass concrete is concrete cast without Rebars. They are good in compression and are mostly used for the construction of gravity structures such as Dams. While reinforced concrete have reinforcement bars in them, which increases the tensile strenght of the concrete.

Dry lean concrete is used as a sub base for structural concrete. It contains much less cement and more sand compared to structural concrete.
Rich is more face to face communications. Lean is e-mail. The less you interact with the audience the more lean you are.

Lean Pockets are healthier than Hot Pockets and come in more varities. They are both produced by Nestle

A lean mix simply means that there is more liquid that concrete in the mix. The mix is thin and pours easier. It is sometimes used when you need to make a base on an uneven surface, like dirt. You would pour the lean mix, and then use it to put the more solid mix on top of.
