Conventional materials continue to be the basis of construction due to their availability, ease of use, associated tools (concrete mixers, elevators, electric vibrators and cutting tools) and their refined techniques.
To know how they work, it is important to know those main characteristics that make them unique and at the same time distinguish them from each other.
Commonly known as Portland cement, it was created by the British Joseph Aspdin and is undoubtedly the most used material to create other compounds. There is a wide variety of cements for different purposes, since they are hydraulic binders that mixed with water result in products that harden and set.
To produce a chemical reaction that generates a flexible mass that adheres, it is necessary to add water to the mixture.
It is important to understand that said reaction is not conditioned by the amount of liquid added. What you get is a hydrated, firm and solid compound that can cope with weather conditions and elements like water and air.
Since it contains hydrated calcium silicate, this element gives it these adhesive properties during mixing. Once it is properly hydrated, it can be used in different ways and as an integral part of a structure. Its usual uses are the foundations, roads and walls of blocks or bricks.
Obtaining the concrete part of using a binder, which is usually Portland cement, water and aggregate fragments. The latter are arid elements that have an average diameter and are classified as fine or coarse sand, gravel and gravel. The variations in this mixture is what will modify the mechanical and application properties of the material.
In terms of construction, the mixture of cement, water and sand has been termed as a mortar. To achieve a more stable, resistant and durable product, you need an aggregate with dimensions similar to small stones or a little larger. Depending on these factors, the concrete will be used for the different structural elements that make up a specific work.
In addition to its name in terms of geography, the difference between concrete and concrete is related to its proportions and modes of use. Its elements remain the same, except for the different techniques that can be used during the process. Depending on the density of its elements, the concrete can be light, normal or heavy.
Another important aspect with respect to this difference is the use of additives in a proportion less than 1% of the total mass of this compound.
These substances can accelerate, retard or color the setting. As with concrete, it can be added fibers, fluidificantes, waterproofing, plasticizers, waterproof, among others.
One of its main characteristics is that it can effectively withstand the effects of compression and tension once solid.
The problem is that for larger structures, it needs to be reinforced to withstand other mechanical loads, such as traction and bending. Hence, internal structures are incorporated to make it more stable.
Concrete or reinforced concrete
This compound derives from the inclusion of steel reinforcements that can be bars or meshes to make it much more dynamic. You can also incorporate some types of plastic fibers in different proportions and depending on a specific design.
It is undoubtedly the most popular material in modernity and is shaped using formwork, which are a kind of rigid molds for emptying during construction. It is commonly used in architecture and engineering to make bridges, tunnels, buildings, harbors, dams and much more.
