A concrete pump is a machine used for transferring liquid concrete by pumping.There are two types of concrete pumps. The first type of concrete pump is attached to a truck or longer units are on semi-trailers. It is known as a boom concrete pump because it uses a remote-controlled articulating robotic arm (called a boom) to place concrete accurately.
17/7/2019 · Benefits of Commercial Concrete Pumping Though the concrete pumps are not specialized in commercial projects, it would be seen quite less at the residential project. But, these concrete pumps are efficient to transfer concrete anywhere.

5. Pouring of Concrete for Concrete Stairs Pouring of concrete into the formworks is started from the below part to above. The concrete mix plays an important role in strength and durability of stairs. Standard mix used for stairs are 3 parts cement, 2 parts sand, 4
10 Properties of Concrete and their Uses. Properties of concrete are influenced by many factors mainly due to mix proportion of cement, sand, aggregates and water. Ratio of these materials control the various concrete properties which are discussed below. 1. Grades of concrete.
17/7/2019 · If the construction project is larger and you've to place more concrete then concrete pumps are best for you. It can place the concrete to the specified location in a steady manner. The concrete pump has got the ability and you can rely on it.
31/3/2019 · 31/3/2019 · While traditional concrete normally has a compressive strength ranging anywhere from 2,500 to 5,000 psi, UHPC can have a compressive strength of up to 10 times that of traditional concrete. After just 14 days of curing, UHPC has a compressive strength of 20,000 psi. This number increases to 30,000 psi when fully cured for 28 days.
Segregation of Concrete – Causes and Prevention. Segregation of concrete is the separation of cement paste and aggregates of concrete from each other during handling and placement. Segregation also occurs due to over-vibration or compaction of concrete, in which cement paste comes to the top and aggregates settles at the bottom.
31/3/2019 · 31/3/2019 · Concrete innovations such as UHPC outperform traditional concrete in all areas of strength, making it a smart choice for any and all concrete projects. The reduced maintenance and increased longevity of UHPC delivers a win-win of superior strength and lower lifecycle costs.
Advantages of Reinforced Concrete. Reinforced concrete has a high compressive strength compared to other building materials. Due to the provided reinforcement, reinforced concrete can also withstand a good amount of tensile stress. Fire and weather resistance of reinforced concrete is fair. The reinforced concrete building system is more
6/5/2016 · 9. Durability of concrete Durability of concrete is its ability to resist its disintegration and decay. One of the chief characteristics influencing durability of concrete is its permeability to increase of water and other potentially deleterious materials.
10+ Uses of Concrete in Civil Engineering. Concrete is one of the most frequently used building materials worldwide. The distinctive characteristics like strength, durability, low-maintenance, energy-efficient, sustainability are the reasons for wide range usage of concrete in the field of civil engineering.

After the concrete is deposited in the desired area by chute, pump, or wheelbarrow, it should be pushed—not lifted—into final position with a shovel. A short-handled, square-end shovel is an effective tool for spreading concrete, but special concrete rakes or come-alongs also can be used.
Concrete with a PSI of 4000 to 5000 is found in warehouses and factories, in addition to other large-scale commercial and industrial properties. 4.) 6000+ PSI Concrete with a PSI rating of 6000 or more is considered high-strength concrete.
22/10/2019 · The use of concrete in commercial buildings makes it safer than using most other construction materials. It is mostly more economic than steel buildings and requires less maintenance. It is easy to control the heat transfer from inside to outside and vice versa which reduces the …
