Concrete is one of the most commonly used materials in many construction projects. From portable mixers to huge concrete mixers mounted on trucks, these pieces of equipment are a common sight in project sites. While it may look pretty straightforward, mixing and pouring concrete is not as simple as it seems. Starting with the mixture and consistency down to the moulds or formwork, everything is done according to strict standards.
Here are the factors you must consider when mixing and pouring concrete:
Aggregates such as crushed rock and sand are typically mixed with cement and water. The mixture ratio would depend on the type of construction the concrete will be used. For instance, the usual ratio in building construction projects is one regular cement bag to three or four similar quantities of aggregates.
The consistency of the mixture would depend on where it is going to be used. Usually, concrete mixtures that are to be poured at ground level have a thick consistency. This is because it does not easily crack over a period of time. According to experts, this type of consistency is best used in driveways, road construction projects, foundations, and pillars.
Nevertheless, if the concrete mixture needs to be pumped several floors up, water is oftentimes added to make it a bit soupy.
Mould or Formwork
A mould or formwork is typically used to hold the wet concrete in place until it completely dries. Whilst some construction companies maintain a number of moulds or formworks in their inventory, they would still shop for additional formworks. When a project is approved, construction firms would usually look for formwork for sale that best fit the project.
Laying concrete is not just about mixing everything in and pouring it out upon achieving what seemed to be a perfect blend. You need to determine the type of construction you are going to use the concrete for in order to come up with the right mixture and consistency. You also need to have a number of moulds or formworks ready for use. Bear in mind that when the concrete mixture sets, there is no way of correcting whatever mistakes you may have.
