Which type of concrete is useful in high rise construction?
Which type of concrete is useful in high rise construction?
Pumped concrete – High-rise construction requires the pumping of the concrete to great heights. Hence, in these construction sites pumped concrete, which is fluid in nature with high workability, is used to enable the pumping of the concrete mix through pipes or flexible hoses.
What type of concrete is used for foundations?
High-Strength Concrete Mix: When durability is key, high-strength concrete makes a great choice. This is ideal for foundations, footers and heavy equipment bases.
What is ready mix concrete used for?
The Characteristics of Ready-Mix Concrete & Delivery This unique character is the basis for why a single material can be ideal for building skyscrapers, bridges, sidewalks, superhighways, dams, and even houses. Furthermore, ready-mix concrete delivery makes this material easy to use wherever it’s needed.
What grade of concrete should I use?
Different types of concrete grades and their uses
| Concrete Grade | Mix Ratio (cement : sand : aggregates) | Compressive Strength |
|---|---|---|
| M7.5 | 1 : 4 : 8 | 7.5 MPa |
| M10 | 1 : 3 : 6 | 10 MPa |
| M15 | 1 : 2 : 4 | 15 MPa |

What are the disadvantages of ready mix concrete?
Disadvantages of Ready-Mix Concrete
- Requires huge initial investment.
- Not suitable for small projects (less quantity of concrete is required).
- Need an effective transportation system from the batching plant to the job site.
Is Ready Mix Concrete good?
Ready-mix concrete tends to be better for many projects, in spite of its higher cost. Ready-mix concrete offers a higher quality, and variation between batches is minimal when concrete is prepared in a plant environment. Ready-mix concrete is normally recommended for large projects that require a high volume.
What is the strongest type of concrete?
Ultra-High Performance Concrete (UHPC) is a cementitious, concrete material that has a minimum specified compressive strength of 17,000 pounds per square inch (120 MPa) with specified durability, tensile ductility and toughness requirements; fibers are generally included in the mixture to achieve specified requirements …
What are the requirements for ready mixed concrete?
The requirements specify a minimum quantity of cement (minimum cement content, or MCC) to be included, but no water cement ratio (w/c) as such, they have relatively low levels of durability.
What are the different types of mixed concrete?
Types of Ready Mixed Concrete. There are three types of ready mix concrete (RMC) depending upon the mixing of the various ingredients as given below: Transit mixed concrete. Shrink mixed concrete. Central mixed concrete.
How many metric cubes per hour in ready mix concrete plant?
The output obtained from a site mix concrete plant using a 8/12 mixer is 4 to 5 metric cubes per hour which is 30-60 metric cubes per hour in a ready mix concrete plant. Better handling and proper mixing practice will help to reduce the consumption of cement by 10 – 12%.
What do you use to level a concrete floor?
It is very easy to mix and use. A concrete floor leveling slurry is a simple mixture of a concrete mix and water. It is a soupy mixture that is often used to fill in spalling in concrete floors, or to level out a sloped or recessed area in concrete.
What are the different types of ready mix concrete?

How many cubic yards of ready mixed concrete?
Ready mixed concrete is usually sold by the cubic yard, with the typical truck mixer holding 9 to 11 cubic yards of material. Determining how many yards you need for square or rectangular slabs is fairly straightforward (you can use this concrete calculator to help you do the math).
When to use high strength or fast setting concrete?
The instructions will include individual setting times. Fast-Setting Concrete Mix: When you need to support a fence or mailbox post, or create a small concrete slab, fast-setting concrete makes a great choice. This sets in just 20 to 40 minutes. High-Strength Concrete Mix: When durability is key, high-strength concrete makes a great choice.
Is it safe to order ready mix concrete?
They’ve found a reliable ready-mix supplier who can get them the right mix, in the right amount, at the right time. In fact, this step of a project is often taken for granted. However, without proper ordering a project can get off to a bad start.
