How to mix 4500 psi cement?
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.
Blind 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.
yes
I think it is twice the cost of ready mix concrete?
A plain concrete with a large ratio aggregate to cement than structural concrete. It is used for filling and not structural duties
a blinding concrete is a thin layer of lean concrete
you can eliminate your oil injection and premix your fuel. Good mixing Ratio would be 50:1 to start but you may go to 40:1 mixing ratio. Watch your plugs and make sure you're not too rich or lean to help you figure out what ratio to use.

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.
use 4:1 lean ratio b)use7:1 lean ratio c)use 2:3 lean ratio d)none
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.
