The use of concrete is an essential part of many construction and renovation projects. The method of adding the concrete, either through pumping or conveying, is an important part of the building project. Concrete will be maximized through one of these methods and the method that one chooses will depend on the type and size of the construction project. Both are effective ways of pouring concrete; however, there are advantages of pumping versus conveying.
When one pumps concrete, the advantage is that there is a quicker placement of the concrete than if one were to use a conveyor. This is beneficial if you have a large project such as a building foundation that requires a lot of concrete. It also decrease the amount of time needed to pour the concrete so one will save on labor costs. Because of the likely quick rate of the placement of the concrete, one will decrease and possibly circumvent cold joints and pour lines. When using a concrete pump, there is more of a variety of choices on how to place the concrete. As well, when you use a pump truck to pour the concrete, there is less water added thereby significantly reducing shrinkage cracks and loss of strength. Pump trucks also help to decrease the amount of site traffic helping to decrease the volume of dirt and mud being dispersed throughout the worksite.
Pumped concrete is much easier to manage as it is poured to the specific designated spot, unlike conveyors which can drop big loads of concrete that have to be manually moved. There are also very little impediments that can obstruct a pumping line. As well, the pipelines have the ability to travel through constricted spaces, beneath or above walls, and cut tight corners which allows the pumped concrete to be poured on difficult to reach areas. There is also a superior mix combination and a more uniform blend of concrete at the point of placement. Pumping concrete also ensures a steady flow of concrete so the pour remains stable and manageable. As well, pumping concrete permits pours on top floors before lower floors.
Conveying involves a bit more consideration for a particular project. For instance, unlike pumping, when concrete is conveyed, it has to be placed as quickly as possible after the concrete mix has been combined and mixed together with the water. As well, low humidity and hot temperature can cause early setting of freshly mixed concrete. This is why concrete that is conveyed has to be placed quickly and efficiently. Conveyors can place concrete but they do not keep the mix properly blended which results in more work when the concrete is placed. Conveyors are primarily designed to transport and place such material as fill, stone, and sand.
Pumping concrete has many advantages over using a conveyor. When deciding which method is best for your project, you have to determine what type of project you will be doing as this is a key factor in determining the type of concrete placement technique that will be used.
