The concrete mix ratio The concrete mix for the subbase must be calculated correctly to achieve good results. In this post, we discuss The keys to performing the calculation
Next, we must add the total amount of dry material that we're going to use, which is 360 kg. So, we'll need to add a total of 28–36 liters of water.
Other factors to consider
Although concrete, on its own, is an excellent building material, we must strengthen it in most projects. The goal is increase their endurance natural and equip it with other features, such as the flexibility. This allows the structure we build to withstand frost, sudden temperature changes, and other conditions that could cause cracks.
A common way to reinforce concrete is to add mesh or fibers. In the latter case, we must use:
500 g for every 60 kg of mix in the concrete mixer
So, the final result will be more durable.
Another important detail is the size of the floor slab and if it's going to be embedded, since that will affect the calculations and we'll need to install expansion joints. We'll arrange 1 joint every 4 linear meters, although this won't be necessary if the floor area is small. We also shouldn't use them if there are at least two open sides. Only by combining both of these factors will we be able to achieve the best results.
In addition, the finish of the subfloor is another factor to consider. In most cases, we’ll need it to be as smooth as possible. This will give the whole project a solid and stable foundation. It is recommended to sprinkle gray cement cigar and use a wet mesh when the concrete It's cool. This way, we achieve a smoother surface, which is ideal for building all kinds of structures.
Why is it important to make accurate calculations?
Calculations, such as the concrete mix ratio, are essential for any construction project. The primary reason for performing them accurately is because save on materials. The more we go over budget, the greater the consumption of resources will be. This will have a direct impact on the total cost of the project, which will ultimately skyrocket. Therefore, we must act with precision and efficiency.
On the other hand, is prevent deviations which could prove disastrous. At first, they won't be noticeable, since they are minor and easily corrected. However, they will become more significant as construction progresses, and it will become increasingly difficult to make adjustments. If we continue down this path, we will end up with a point of no return in which the best solution will be to demolish it, with all the resources and time lost.
In that regard, about accurate and well-executed calculations They provide us with a useful point of reference. Without them, we can only rely on assumptions and hunches. Therefore, it’s well worth taking as much time as necessary before getting started and not acting recklessly. That way, we’ll avoid the problems mentioned above.
Construction will also be delayed, which is something best avoided. Keep in mind that delays will always occur for various reasons. Perhaps a truck carrying materials had a flat tire or got stuck in traffic. In these situations, chance is the cause of the delay. However, we must minimize backlogs caused by human factors, which can be entirely avoidable. That is why it is necessary to follow a plan and act in an orderly and decisive manner based on established calculations.
In short, these are the key steps for calculating the concrete mix ratio for a floor slab. As we have seen, it is important do some accurate calculations, as they will help you avoid all kinds of problems. However, to explore this and other aspects in greater depth, at Structuralia we have a wide range of Master's Degree Catalog related to the architecture and engineering, which help expand knowledge in this field.
