ADVANTAGES AND DISADVANTAGES OF CONCRETE

Sep 12, 2017 · Concrete is an inexpensive, quick and durable way to complete many construction projects. However, there are advantages and disadvantages associated with this material. For example, while concrete becomes stronger and more durable with time, it is susceptible to water and freezing temperatures, meaning that water can seep into cracks and cause

Jun 24, 2019 · Their preparation process involves suction of excess water using a vacuum pump without waiting for the concrete mixture to set. This process hastens the strengthening period of the structure from 28 days to around ten days. Pumped concrete – High-rise construction requires the pumping of the concrete to great heights. Hence, in these

Types of Concrete Construction Equipment

A concrete pump is a kind of equipment used for transferring liquid concrete by pumping at construction sites. Concrete pumps help in placing concrete faster and more accurately with less labor than any other method. By employing on-site concrete pumps, one does not have to allocate any personnel for placing of concrete at construction site.

Concrete pump - Wikipedia

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.. Boom pumps are used on most of the larger

Concrete for High-Rise Buildings| Concrete Construction

Concrete for High-Rise Buildings. Modern high-rise concrete buildings are models of design skill in the use of materials. It is now a commonplace to specify high strength concrete, usually 5,000 psi, for compression members in the lower stories of multi-story buildings. Concentration of reinforcing bars in these members is very high.

Concrete Pumps | What is a concrete pump?

A Static Concrete Pump, also referred to as a Stationary, Line Pump or Trailer Mounted Concrete Pump is mounted on a trailer and requires a separate pipeline to be attached reaching to wherever the concrete needs to be placed. The pipeline is a series of steel or rubber pipes, known also as concrete …

Mar 19, 2017 · Fresh concrete is that stage of concrete in which concrete can be moulded and it is in plastic state. This is also called "Green Concrete". Another term used to describe the state of fresh concrete is consistence, which is the ease with which concrete will flow. The transition process of changing of concrete from plastic state to hardened state.

16. Vacuum Concrete Concrete with water content more than required quantity is poured into the formwork. The excess water is then removed out with the help of a vacuum pump without waiting for the concrete to undergo setting. Hence the concrete structure or the platform will be ready to use earlier when compared with normal construction technique.

Concrete–Lined Ditch Irrigation System

Concrete with water content quite the desired amount is poured into the formwork. The surplus water is then removed out with the assistance of an air pump while not looking forward to the concrete to endure setting. Thus, the concrete structure or the platform is going to be able to use earlier in comparison with traditional construction technique.
