There are many very good reasons to prefer the use of ready-mix concrete in your architectural or engineering work. From concrete Construalcalde we will tell you about the characteristics of ready-mix concrete.
Ready-Mix Concrete for Construction
Ancient builders developed combinations of stone materials of volcanic origin which, when mixed with water and then dried, possessed adhesive and hardness properties. adhesive properties and hardness that were very useful for carrying out constructions that have withstood the passing of the centuries. With the arrival of the modern era, experimentation in the manufacture of concrete was resumed, achieving at the end of the XVlll and XlX century XVlll and XlX the first concretes with resistance to compressive forces never seen before. never seen before.
Advantages of Ready-Mixed Concrete
Today, the use of concrete is widespread in the world, and its physical and chemical characteristics can be controlled through a careful selection of admixtures and aggregates. In all construction sites, concrete is manufactured for each specific need. The big question is: Why should ready-mix concrete be preferred over site-produced concrete?
Some of the advantages of ready-mix concrete are:
Types of ready-mix concrete
Concrete characteristics are established according to the element to be constructed, its requirements and specifications. Some concretes are pumpable, and others, due to their physical configuration, must be placed by other means. Among the most common types are:
- Standard ready-mix concrete. The most common mix and form of concrete, with applications in general civil works.
- Architectural and decorative concrete. Stone components and additives are added to obtain different textures and colors, according to the design of the work.
- Fast-setting concrete. This concrete is configured in its mix with special additives to obtain maximum hardness in less time, allowing the removal of falsework and significantly reducing construction times. It is recommended when building in temperatures below 10°C (50°F). In addition, this type of concrete has above-average durability and acid resistance.
- Fiber-reinforced concrete. When fibers are added to the concrete mix, they enhance the concrete's resistance to cracking or rupture. Its application in structural elements favors resistance during the early stages of setting.
- Fluid backfill. This type favors the pumping of ready-mixed concrete and its behavior when integrated with elements such as reinforcement, pipes and other elements, generating more solid elements with integrated facilities.
- Concrete for compaction. This mixture is compacted on site with rollers, with minimum slump and high resistance to the presence of fluids. Used in the construction of drains and works exposed to constant flow of water and other elements.
- Self-compacting concrete. With a very fluid composition, it has the ability to self-level without the need to apply vibration. By using plasticizers, the resulting resistance of the element can exceed 50 mta.
- Porous concrete. The distinctive characteristic of this material is its permeability, which allows it to avoid the accumulation of water on its surface, favoring filtration and, when used in pavements, avoids puddling and helps the recovery of phreatic mantles. It favors the grip of tires on its surface, and is less hot than non-porous concrete.
In addition, there are many other additional properties that are integrated into concrete for specific purposes, such as the ability to repel bacterial growth, for use in operating rooms, kitchens, and spaces that require specific sanitary conditions.
