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.
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.
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:
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).
In addition, the advantages include low weight, impact resistance, and the elasticity is much higher than that of standard concrete.
Along with many positive aspects, polymer concrete has certain disadvantages:
- Susceptibility to the effects of open fire, as well as elevated temperatures, which can cause destruction of the material.
- 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.
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:
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.
|Ingredient||Compositions of the proposed polymer concrete, weight in%||
|Epoxy resin||5.4||4.76|| 4. |
|5 ... 2-5. 21|
|Polyethylene polyamine|| 0. |
|Varnish KO-916K||-||-||-|| 0. 03-0. |
|Varnish KO-922||0.09||-, 08||0.16||-|
|Mineral type filler||21.77||19.19|| 19. |
|Placeholder||71.93||75.26|| 75. |
Now it is worth considering the detailed 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.
Polymer composite material is used for various fields, and is also an excellent basis for creating various types of products:
Polymer concrete is quite difficult to distinguish from natural granite or marble, which it successfully imitates. Due to the low weight of polymer products, there is no need to build a reinforced reinforced base, as well as to make additional reinforcement of the structure. Also, the material is completely immune to temperature effects and humidity levels, it can be easily installed, durable and has an original texture.
The ideally smooth and shiny surface of the products allows the products to maintain their beautiful appearance, while being open in any weather conditions.
Polymer concrete can be used to make stairs, floors, facing and sidewalk tiles, building structures, sculptures and drainage trays, monuments, even fountains!
Moreover, manufacturing using polymer concrete technology makes it possible to use it to create:
Now let's look at how this material is made.
The technology for creating polymer composite concrete and manufacturing of products will include the following stages:
- Preparation of all components.
Let's consider everything separately. During the manufacture of the material, the most important thing is the optimal selection of all components that will meet the intended purpose.
How to prepare all components
When you are familiar with the composition of the composite, prepare all the components in order to perform mixing:
How to make a mixture?
Making a mixture
The polymer composition should be prepared according to the suggested algorithm:
- Place the crushed stone in the mixer, and also add quartz sand and filling ingredient, while following the sequence suggested in the instructions.
- Mix the ingredients for about 2 minutes, add hot water and re-mix.
- Soften the binder with an additive such as thinner.
- Insert plasticizer into resin, mix well.
- Stir binders with aggregate, add component to cure.
- Mix thoroughly for about 3 minutes.
Now that the composition is ready, you should immediately start pouring, since the material has properties to quickly harden.
Proceed with the following sequence:
This is where the instruction ends, you just have to rejoice at the fruits of your hands.
Now that you yourself know about all polymer concrete technologies, you can make your own composite material. If you have any doubts, read the information again, as this is a consultation of professional builders, which will help to avoid mistakes.
