Concrete pump - all about pumping concrete
Pumping is an efficient way of placing concrete while constructing buildings.
This method is very economical and practical. This method of placing
concrete proves to be very helpful while constructing high-rise buildings
or while placing large slabs where the concrete truck cannot reach the
concrete.
Types of concrete pumps
There are namely three types of pumps used to place concrete, namely,
boom pump, line pumps and separate placing pumps. A boom truck is a self-constructed
unit, which consists of a frame, a truck and pump through which it pumps
concrete. This type of concrete pump is mainly used for concrete slabs
and medium high-rise buildings and also for large volume commercial and
industrial projects. On the other hand line pumps are versatile and portable
units. They are used to pump not only structural concrete but also grout,
wet screeds, mortar, shotcrete, formed concrete and sludge. Separate
concrete placing booms are used as an alternative to boom truck.
Functioning of a concrete pump
The concrete is separated from the pump line with the help of certain
lubricating materials such as water, cement and sand. It is very important
to mix all the components in the right proportion and content. All the
concrete mixtures should be specified as 'pumpable'. There are many mixtures,
which are not pumpable, and hence they get clogged in the pump-line.
Hence it is very essential to choose the right kind of concrete mixture.
After this the concrete is discharged into a truck.
Safety precautions
While using concrete you need to undertake certain precautions. It is
advisable to choose the right kind of hose. Hose are manufactured for
specific applications. They are designated as a point of placement for
discharge. Also you have to be conscious about the attire you wear while
handling concrete pumping. The clothes you wear should be well aerated
and easily allow grout to escape. It is also important to use proper
system for pumping concrete. The system should be properly tied-down
and should not be accident-prone. It is also advisable to check the brakes
of the machine too. The system should be regularly cleaned and maintained.
The clogs, if any, should be removed and the system should be regularly
cleaned with the help of compressed air.

Precast concrete - the long-lasting miracle
Pre-casting concrete is an ancient concept. However with the development in the technology of construction, the technique developed for precast concrete is fairly modern, since it never existed before the 20th century. This is a technique where the...
