What is difference between lean concrete and PCC?

The main difference between lean and PCC concrete is that lean concrete contains less cement compared to the water content present in it. This means, when compared to plain cement concrete (PCC), the lean concrete has a smaller ratio of cement to water content.

What is a lean concrete?

Lean concrete is made up of low cementitious material content. It is primarily poured through chutes, conveyor buckets, or pumps. It is used in various areas where support and strength are not critical. The mixture is highly liquid when compared to real concrete and is self-leveling, making it ideal for saving time.

What is lean and rich concrete?

A rich mixture contains a high proportion of cement. A lean mixture is a mixture of concrete or mortar with a relatively low cement content. A harsh mixture of concrete is one without mortar or aggregate fines, resulting in an undesirable consistency and workability.

What is advantage of dry lean concrete?

Advantages оf Dry Lean Concrete Provides even and stronger support to the hard floor. It has a high resistance to deformation. It has excellent improved load transfer efficiency at the joints. Helps in all weather conditions.

How much cement do I mix with lean?

1 part cement. 2 parts fine aggregate (sand) 4 parts coarse aggregate.

How thick is lean concrete?

Lean concrete: Its role is to provide the uniform surface to the foundation concrete and to prevent the direct contact of foundation concrete with the soil. Its thickness is 5. It is mixed at 150 kg/m3.

What is the grade of lean concrete?

As far as Civil construction is considered, the ratio of concrete is 1: 3: 6 (M-10) and below, which is called lean concrete. Generally 1: 3: 6, 1: 4: 8 and 1: 5: 10 mixes are used for lean concrete mixes.

Which grade of concrete is used for PCC?

M15 grade
The Grade of the PCC used is M15 grade. IN M15 Grade, The mix ratio is 1:2:4. (1 cement,2 sand , 4 aggregates). Applications: M15 grade plain concrete cement is used for levelling courses,bedding for footing, beams and columns e.tc.

What grade is lean mix concrete?

C7 & 8 concrete mix, Gen 0 concrete or wet lean mix concrete, is commonly used in both commercial and domestic projects for a huge range of general applications, such as kerb bedding, haunching and backing, domestic foundations and blinding.
