Stressed concrete beams have a variety of uses in civil engineering. They hold up roofs and bridges among other things. -These concrete beams are not just concrete, they have steel cables inside that create a tension to make the beam stronger.

∙ 13y agoConcrete is the most widely used man made material on this planet, because of its great construction qualities. It is a combination of a binding material which may be cement or other like fly-ash, mud etc. and some ballast, usually gravel, or sand and sometimes some additive minerals in appropriate quantity. With the exception of cement, all of the constituents of concrete are naturally and easily available materials. Cement is an easily available factory made material. When the 'green' mix of concrete is left to harden under appropriate curing conditions, it gets strength equal to or more than stone. Concrete is the backbone of civil engineering.

What mix is used for dry lean 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.
What is the difference between lean and blind concrete?
Blind Concrete
What is lean concrete?
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.
What is the difference between lean concrete and mass 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.
Is lean concrete the same as flowable fill?
yes

What is the difference between leAn concrete and ready mix concrete?
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.
What is the use 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.
What different of blinding concrete vs lean concrete?
a blinding concrete is a thin layer of lean concrete
What is dry lean concrete?
A plain concrete with a large ratio aggregate to cement than structural concrete. It is used for filling and not structural duties

Lean concrete - having a discussion with someone - lean concrete is not as waterproof as shotcrete Any opinions thanks?
A lean mix of concrete is a weak mix (ie. Gen 1 or C10 for example). As for how waterproof a lean mix is compaired to a shotcrete mix, it would depent on what mix of shotcrete is used. Generaly speaking, whatever mix of concrete is used if it dose not have a waterproofing agent in it (ie. Sika 1+ Waterproofer for example) it wont be that waterproof. But if you want a staight answer, I would say shotcrete would be more waterproof, only because it tends to be a stronger mix. Regards Colin, a concrete batcher for Tarmac.

How much does a yard of lean concrete cost?
I think it is twice the cost of ready mix concrete?
Why lean concrete is provided in foundation?
Lean concrete is used to provide a level surface , where main foundation (raft, iso lated or any other type) can be placed. also another purpose is protection of main foundation from soil below, as moisture or other chemicals in soil like sulphates may attack concrete and can weaken it
