Uses and benefits of concrete pumping

Concrete pumping is the latest technology applied in the modern construction industry to set the concrete in all the structures ranging from high skyscrapers to the slightest convenience store. With concrete pumping, it is possible to arrange the concrete where it requires to fit.

Concrete pumping is the most convenient method for pouring concrete through a machine to transmit the liquid concrete. Normally, two basic types of pumps are utilized in concrete pumping i.e. boom pump and line pump.

Boom pump – It is self-contained unit that comprises of the frame and a truck. It is mostly applied to pour concrete in high up or difficult to arrive at the location.

Line pump – It is a portable unit that can pump structural concrete along with mortar, shotcrete, grout, wet screeds and foamed concrete.

Given below, some useful benefits of concrete pumping :-

Huge savings in time - Time is significantly reduced as the time is only required for mixing concrete and delivering to proper location.

Besides, the crew doesn’t have to make way for concrete trucks to pour the concrete to all the various locations.

Greater Productivity – The concrete pumping allows the crew members to deal with other aspects of the project since they don’t require to utilize shovels and wheelbarrows for the purpose of shifting concrete where it requires to fit.

Higher Precision – As the concrete pump expands from the truck right to the proper location the concrete is required, the entire process is error-less and precise.

This precision helps with productivity, wasted concrete because of spillage and fewer times for cleaning up.

Curtailment in labor costs – Less workers are required to set up and utilize the concrete pump as compared to the standard method of executing things. As less workers are needed, the labor cost is also reduced considerably and a more gainful project is created for the builder.

Greater employee safety – The employees needed to drive the concrete pump remain safe as compared to the employees assigned to mix and move the concrete with the conventional method.

With concrete pumping, heavy lifting is not required and as concrete moves directly to the spot, it requires less possibility for mishaps that can lead to severe injury.

Applications of concrete pump:

Residential projects similar to walls, foundations and patios.
Agricultural projects similar to sheds, barns, silos and bunkers.
Civil projects like hydro stations, water treatment plants or bridges.
Commercial or industrial projects similar to high rise buildings, ice rinks, strip malls and factories.

Different categories of sands and their applications

The sand is mainly applied for rock particles which mainly vary in grain size among 2 mm and 1/16 mm. In composition, they are primarily an oxide of silica SiO2.

Mineralogically, they mostly include broken grains of mineral Quartz (SiO2) that is formed due to the crashing of sandstones and equivalent rocks.

Categorization of Sands: Sands are classified variously on the basis of their Based on the mode of origin, composition, and grain size, the sands are differently categorized.

The mode of origin: With adherence to the mode of origin, there are three types of sands like pit sands, stream sands and marine sands..

The pit sands are generally sharp and angular in outline. Winds generally deposited them and develop accumulations in soils covered by clays. Good quality mortars can be produced from these sands by purifying and cleansing them properly.

The river sands come about large accumulations along the base and banks of all the rivers in plains and semi-hilly areas. The shape of the sand grains in river sands appear almost round (because of significant movement in river waters).

These do not contain clay, salt encrustations, and organic impurities. So, these are frequently utilized to produce mortars, plasters, and concrete.

The marine sands are found on beaches and along the seashores. Similar to river sands, they comprise of rounded grains of quartz. There are some problems with these sands as their grains are mostly wrapped with coatings of salts from sea water.

These salts can’t be separated easily. So, if these salts are utilized with mortars or concrete, a reaction occurs with the binding materials and produce lots of difficulties. Beside, the salt encrustations are often hygroscopic, it means they consume moisture from the atmosphere.

It also leads to delayed setting, dampness. Besides, efflorescence may also happen in mortar or concrete that is formed with these sands. Therefore, the quality of marine sands is substandard and should not be recommended. But, in case of requirements, marine sands should be cleansed perfectly prior to utilize them.

In order to learn how sand is categorized on the basis of composition and grain size, go through the following construction article.
