Advantages of polymer concrete over other materials: Review + Video Characteristics of polymer concrete - what makes it better than ordinary concrete. In our time of development of building technologies, many new materials appear, as well as concrete mixtures, for the preparation of which special fillers are often used. This makes it possible to create durable composite-type materials that have high performance and excellent decorative properties.

Polymer concrete is just such a composition that was able to gain popularity in the market with construction raw materials in record time.

General information

Please note, the material, together with the standard components - crushed stone and sand, includes a binder like polymer resins based on furan, epoxy and polyester.

Polymeric concrete is in great demand in the field of construction, and it is also used to create sculptures, make original furniture, and is also often used in the ritual sphere.

Polymer concrete (polymercement, cast stone, plastic concrete, plastic concrete, concrete polymer) was created in America as a stronger and more durable alternative to standard concrete. The polymer variety of the material has many more serious advantages, which are associated with improved mechanical characteristics (compared to ordinary concrete), resistance to aggressive chemical environments, lightness, a large color palette, which makes it possible to make an imitation of natural stone. Consumers of the composite material were able to make sure that this composition is reliable and has a wide range of applications. Let's take a closer look, delve into the manufacturing technology, evaluate all the advantages and disadvantages of the material, and also study the recipe in more detail.

Advantages of the material

Interestingly, that the composite type of concrete due to its recipe features has a number of positive characteristics. They are used in many different situations where using standard concrete will not provide the desired result.

The main advantages of the material of composite origin:

  1. Advantages of polymer concrete over other materials: Review + Video Increased level of resistance to moisture penetration into the composite array. Water droplets will quickly evaporate from the surface of the material, and at the same time they will not have time to get saturated with its destructive moisture.
  2. Resistance to large temperature changes, which makes it possible to maintain the integrity of polymer concrete, regardless of how long the freeze is and how many freeze-thaw cycles have been.

    This material is one of the varieties of concrete mixes, in which polymers are used instead of cement or silicate (which is used to make standard concrete material).

  3. Resistance of the material to aggressive substances, chemical reagents of any origin, which allows the use of polymer concrete in different areas without surface protection with special coatings.
  4. It is possible to restore damaged areas due to mechanical stress by using a restoration mixture for a composite array.
  5. Increased strength characteristics of polymer concrete with a relatively low weight. This makes it possible to create various products that have enhanced performance properties.

  6. No roughness on the smooth, perfect and completely non-slip surface of the material. This property allows the stone of artificial origin to remain clean for a long time, and, if necessary, you can easily remove various types of dirt from the surface of the material.
  7. A huge range of colors of polymer concrete, which makes it possible to imitate the stone of natural origin, granite and malachite. The manufactured artificial stone is very difficult to distinguish from the real one, and this makes it possible to provide the composite with a wide range of applications.
  8. There is an opportunity to perform recycling, which is used in the manufacture of waste of a technological nature, and this helps to significantly reduce the cost of products that are produced using waste-free technology.

In addition, the advantages include low weight, impact resistance, and the elasticity is much higher than that of standard concrete.

Disadvantages

Along with many positive aspects, polymer concrete has certain disadvantages:

  1. Susceptibility to the effects of open fire, as well as elevated temperatures, which can cause destruction of the material.
  2. Much higher cost (when compared with ordinary concrete), because this is due to the cost of purchasing special resins that are included in the composition.

Although there are drawbacks, and this is spoken about openly, there are much fewer of them, which means that we can say with complete confidence that the material is excellent and polymer concrete products will serve you for many years.

Components that make up

If you want to make polymer concrete at home, you should first study the composition of the composite.

In order to prepare polymer concrete on your own, you should use the following ingredients:

  • Binder component, which is used as polyester, urea-formaldehyde, furfural acetone and epoxy resins.
  • Crushed coarse-grained filler. The size of the fraction of crushed stone required to make a composite can be up to 4 cm, but crushed stone having a size of 1-2 cm should make up most of the total composition.
  • Quartz sand that has been previously cleaned and sieved. The quartz particle size should not be more than 0.

    5 cm, and in no case is the presence of clay inclusions, as well as dust, allowed. For polystyrene concrete, for which polystyrene is used as a filler, there are slightly different standards.

  • Crushed graphite powder, the size of which is not more than 0.015 cm, quartz flour - when used as a ground filler, the need to use expensive resins is eliminated or at least partially reduced.
  • Gypsum of construction grade, used in the presence of urea-formaldehyde type resin in the composite formulation.
  • Surfactants, bulk bulking ingredients and antiseptic additives help to enhance the thermal insulation properties of the finished composite concrete.

Now it is worth considering the detailed classification.

Classification

Polymeric concrete, depending on what concentration of filler it has, the proportion of which in the entire volume is up to 4/5, can be divided into classes:

  • An especially heavy composite material, its 1 meter cubic will weigh from 2.5 to 4 tons.
  • Heavy, the density of the material ranges from 1.8 to 2.7 per meter 3 .

  • Lightweight, which has a specific weight of 0.5 to 1.8 tons per 1 m 3 .
  • Lightweight, and its mass per 1 cubic meter is not more than 0.5 tons.

Before considering the technology of polymer concrete, you should learn more about where it is used.
