How to use liquid glass for concrete: instruction. For construction, concrete mixtures are often used, which, after hardening, have increased strength. To perform all sorts of tasks, various impurities are sometimes added to concrete, additives that help change the general characteristics. One of the most popular elements is precisely liquid glass for concrete. It helps to reduce the hardening time of the concrete mixture, increases the resistance of the monolith to moisture, high temperature and various acids.
It is important that the proportions of water glass in concrete for waterproofing are correct so that the material is guaranteed to obtain the required strength characteristics. Let's take a closer look at what this additive is.
Most of us have heard that in construction they often use an additive called "liquid glass". But it turns out that not everyone knows what this supplement is. The ingredient in question is dissolved potassium and sodium silicates in water and they are derived from silica.
Probably everyone has encountered a water-based solution of silicates when they used silicate glue for domestic needs. The material is visually a viscous liquid with a whitish-yellow tint. Let's first consider the manufacturing technology, according to which the material can be divided into several types.
Due to the fact that there are many advanced technologies, this additive can be obtained in different ways. The component itself is made by processing high temperatures of silicon raw materials together with an aqueous solution of sodium hydroxide.
The equipment makes it possible to obtain an ingredient that will have the desired properties by sintering soda with quartz particles. You can also use a method of mixing the alkaline solution and silicon dioxide.
Two types of components can be obtained, depending on the manufacturing specifics:
Please note, that the performance characteristics of the two types of materials are the same, but the sodium composition has a lower price.
Why add liquid glass to concrete
The use of a silicate solution, which is introduced into the concrete mixture during preparation, and also external treatment of the concrete surface helps change the properties of concrete.
After the introduction of liquid glass into the solution, concrete receives the following additional characteristics:
Important! In order to achieve the required characteristics when mixing concrete and water glass, it is necessary to strictly observe the proportions.
All the advantages and disadvantages
As well as other building materials, this additive has its advantages and disadvantages.
The pluses are:
Moreover, the silicate component has:
The additive can inhibit the development of bacteria and also impairs the performance of microorganisms.
The disadvantages include:
Please note, that even despite all the disadvantages that exist, the additive is often used even by professional builders, private developers, as well as home craftsmen in order to solve a wide range of tasks.
Workers in the field of repair and construction often use silicate solution based on potassium and sodium.They help to improve the performance characteristics of the monolith, and this makes it possible to use it for all sorts of purposes.
The area of application for the silicate type modifier is as follows:
Interestingly, that, in terms of its characteristics, the component has almost no analogues for performing works that are associated with impregnation and waterproofing.
The properties of the silicate-type material make it possible to provide reliable protection of a concrete structure from moisture, temperature rise and other aggressive environments.
We suggest looking at popular recipes to know how much liquid glass to add to concrete for different tasks.
To create modified cement mortar and concrete, use the following guidelines:
. It remains to mix everything well until smooth, and then you can use the ready-made solution.
It is very important that all components are added in the same amount, and then, when you gradually add water, you will need to achieve a creamy consistency.
Provided that you adhere to the proportions, the concrete solution will receive all the necessary properties.
How to properly fill
Sometimes there are situations when the introduction of liquid glass does not bring the desired result. This is due to the fact that you have no practical experience, and also you do not respect the proportions.
It is important not to forget the following:
First, you should mix all the ingredients, and then dilute the silicate with water. After that, pour everything in and mix well.
Remember that an increased amount of silicate-type filler, as well as a reduced amount, will negatively affect the properties of concrete.
We introduce liquid glass into concrete
In order to obtain the required effect from the use of the additive, it is necessary to study the rules for working with a silicate-type additive, and also prepare the required tools immediately.
For surface treatment of a concrete mass, the following is required:
General rules stipulate the following:
If the coating is applied in two layers, it will penetrate to a depth of about 0.2 cm. The modifying composition does not contain harmful components, but if a silicate solution gets on the skin, it should be rinsed thoroughly. After the work is completed, you should carefully inspect and rinse the tool from the remnants of the mixture with liquid glass.
Please note, that you can add an additive inside the concrete mortar even during preparation.
To do this, you need to gradually add water glass for concrete to a concrete mixer or container. The instructions for use must be followed exactly to ensure the required concrete performance.
To properly use liquid glass for concrete and prepare a good modified composition, you will need:
The algorithm for preparing the improved concrete composition includes the following operations:
Interestingly, that if you yourself pour liquid glass into concrete, then all proportions should be strictly observed. Exceeding the amount specified in the recipe will cause accelerated drying of the concrete and cracks will appear. Adding a reduced volume to liquid glass concrete will not provide the required performance for operation. .
To ensure the required performance of concrete, the proportions should be observed when pouring water glass.
Guided by the recommendations from professionals, as well as observing the recipe tested in practice, it is possible to provide the required properties of the working type for the monolith. Due to the fact that the silicate additive is inexpensive, the cost of concrete mortar does not increase significantly, and the performance properties improve tenfold, and such concrete can be used to solve a wide range of construction problems. If you additionally consult with specialists, you can avoid mistakes.
