Ultra concrete - characteristics and production

There are many types of concrete, among which there are heavy and light types. This article will focus on dense material, which is produced in the form of pellets. We will consider below how to make ultra-concrete with our own hands using vibratory casting into molds.

General information

You may have met such names as Kevlabeton or granilit, but they are produced using the same technology, the essence of which is the same - a pellet of concrete is created that looks like a ball.

This is facilitated by the use of a modified concrete mixer. In fact, the technology of ultraconcrete, although it has different names, uses the same method of preparation of the material, recipe and raw materials.

The process is reduced to the fact that from the concrete mixture, which is prepared according to a special recipe, they begin to remove air. To do this, use a gravity mixer, in which the pellets are obtained with a low ratio of water and cement, which increases their density.

This method makes it possible to obtain an imitation of natural materials, such as:

• granite;
• malachite;
• amber;
• marble,

and also color modulations.

This is a very durable, modern and new type of concrete, which is used for the manufacture of:

• paving slabs;
• curbs;
• fences;
• front stone;
• fireplaces and other MAFOV.

Use of material

Ultraconcrete is based on fundamentally different decisions made in the field of manufacturing decorative architectural colored concrete by the method of gravitational curing. In this case, it is possible to obtain a product with high physicomechanical parameters.

The surface of the casting has perfect density and high gloss. At the same time, it is possible to obtain a color range of varying complexity, regardless of the area of ​​the cast element and its overall dimensions. This creates the effect of a natural or artificial material in the range from plastic to malachite.

In the production of building materials for architectural and landscape works they use effective schemes, with the help of which it is possible to obtain new types of concrete.

For disclosing the range of their application, various are used:

• raw materials;
• knitting;
• placeholders;
• plasticizers;
• experiments with the methods and steps of adding chemical modifiers, as well as mineral active additives;
• optimization work with the composition of multicomponent concrete;
• methods of technology management.

To create products, almost any form-building tooling and forms are used. At the same time, the products have high physicomechanical properties, which combine high compressive strength values ​​- B 40-90. This is akin to concrete grades M600-1200 and above.

Manufacturing process

Below is a guide that will help to understand this issue:

1. At the first stage, it is necessary to enter the previously calculated mass of aggregate into the modified concrete mixer..

Tip: be sure to control the moisture content of mineral aggregates.

1. The process of mixing until a homogeneous mass lasts no more than 1 minute. At the same time prepare an aqueous solution of a plasticizer.

Tip: you need to control the temperature of the water that is used for mixing the plasticizer.

1. Add the necessary amount of Portland cement to the modified concrete mixer and mix everything for one minute.. At the same time prepare the right amount of pigments according to the tinting recipe. Usually use a table of colors.

1. Add a dose of plasticizer solution with water to the dead zone of the installation. In this case, the order of water supply will affect the size and amount of pellets.

1. After 15-20 seconds, conduct the primary control pellets, after 1 minute - the final. It is necessary to examine the appearance and check the density of the pellets, as well as the dryness and density of their internal structure, for which the pellet should be broken.

1. Spend tinting, and after 10 seconds (not later), unload the pellets into the forms. In parallel with this, turn on the vibrating table.

1. Turn off the vibrating table, remove the tray with the forms from it and move it to the place of strength setting..

Tip: cover the form or the entire pallet with polyethylene film.

1. Disassemble after 18-20 hours, if used hardening accelerators - 4-8 hours and store finished products.

Raw material

The composition of ultra concrete looks like this:

Tip: if you want to dye ultraconcrete in a specific color, use dyes and pigments to color concrete.

Conclusion

Ultraconcrete is a completely new and modern production technology. It gives you the opportunity to create a material with unique characteristics. For the production it is necessary to have special equipment.
