Liquid glass for concrete: for what and how much is added? Pros and cons of use, proportions, cooking scheme

Because of its special qualities, liquid glass, also referred to as sodium silicate, has gained popularity as an additive in concrete construction. It improves the strength and durability of concrete when combined with it, which makes it a great option for a variety of construction projects. However, what is liquid glass exactly, and how is it supposed to be used?

Concrete’s water resistance can be greatly increased by adding liquid glass, which makes the material perfect for structures that are exposed to moisture. This covers water tanks, basements, and foundations. The compound forms a barrier against water infiltration by filling the pores in the concrete and penetrating it. This keeps the concrete from getting damaged and increases its lifespan.

For the intended advantages to be realized without sacrificing the mixture’s integrity, the quantity of liquid glass added to concrete is essential. Generally, it is advised to use 5–10% liquid glass to the total weight of cement. This keeps the concrete workable while guaranteeing peak performance. To get a consistent blend, it’s critical to thoroughly mix the solution.

Liquid glass in concrete has a number of benefits. It lessens the concrete’s susceptibility to wear and corrosion by strengthening its hardness and chemical resistance. It can also improve the material’s thermal resistance, which is advantageous in situations where temperatures are extremely high or low. But there are a few disadvantages to take into account. Precise measurement is crucial because using too much liquid glass can cause the concrete to become brittle and more difficult to work with.

The first step in creating a liquid glass-enhanced concrete mix is to mix the dry ingredients (aggregate, sand, and cement) as normal. The liquid glass should be diluted with water in a different container using the suggested ratios. Stirring constantly, gradually add this solution to the dry mix until a uniform consistency is reached. By distributing the liquid glass uniformly throughout the concrete, this technique guarantees consistent performance throughout the structure.

Topic Details
Liquid Glass for Concrete Liquid glass, also known as sodium silicate, is used in concrete to improve its water resistance and durability. It is typically added in small amounts, around 0.5-2% of the cement weight.
Pros Enhances waterproofing, increases strength, and improves resistance to chemicals and abrasion.
Cons Can cause the concrete to set too quickly if not properly mixed, may lead to brittleness if overused, and can be challenging to work with.
Proportions Commonly added at a ratio of 1-2 liters per 100 kg of cement. It"s important to follow specific instructions for the product used.
Cooking Scheme Mix the liquid glass with water before adding to the concrete mix. Ensure thorough blending to avoid lumps. Gradually add the mixture to the dry ingredients while continuously stirring.

The main characteristics of liquid glass

Resistance to moisture. This criterion makes it possible to use liquid glass-infused concrete in highly humid rooms.

Resistance to temperature. This enables the creation of warm floors, fireplaces, and furnaces out of such concrete.

Steep capacity. When sealing any cavities or cracks, this item is crucial.

Acid resistance. The resistance to an aggressive environment increases when silicates are added to the concrete solution (this item is effective if you use concrete in the chemical industry)

Types of liquid glass

The process of manufacturing solutions comes in a variety of forms. Let’s examine the fundamentals:

  • Sodium solution – has an increased level of adhesion. It is considered a wonderful adhesive composition. Has resistance to the pernicious effects of atmospheric factors. The main advantage is a rather low price.
  • Potassium additive solution – a sufficiently rapid time of drying was noticed. Resistant to high temperatures. Good for cladding fireplaces and furnaces. Models of this composition have a high price.

Sodium silicate, commonly referred to as liquid glass, is a multipurpose substance that improves the strength and waterproofing of concrete. It greatly improves the concrete’s resistance to water, chemicals, and physical wear when added in the right amounts. Usually, a small amount of liquid glass is combined with water and added to the mixture of concrete. Improved longevity and less maintenance are the key advantages; however, there is a chance of incorrect mixing, which could compromise the integrity of the concrete. To achieve the desired results without sacrificing the performance of the concrete, it is essential to understand the proper ratios and mixing techniques.

Advantages of liquid glass

The following are the most common benefits of adding liquid glass additives to concrete:

  • Effective protection against harmful effects on the surface. Since glass acts as a barrier from all influences on concrete – the surface will never change its shape and will not deform.
  • Protection against pests.
  • Changing the appearance for the better.
  • The basis for further processing of the product or premises.
  • Simplicity of use.
  • Due to the coating, moisture does not get to the surface and it becomes wear -resistant.
  • Durability and resistance.
  • Large segment of the selection of manufacturers.
  • High adhesion for all surfaces.
  • Prevents cracks and corrosion.
  • Many models to choose from.
  • Easily applied on the surface.
  • Resistance to atmospheric factors.
  • It has antiseptic characteristics.
  • It has the properties of sealing.

Disadvantages of liquid glass

Even though concrete that has been mixed with liquid glass has many advantages, there are drawbacks as well:

  • Collapses from physical influence.
  • Not designed to work with a brick base. Certain and the most fat minus.
  • Small smell in some models. It is necessary to work with protective equipment.
  • The need to apply several layers.
  • The composition contains harmful substances that can harm your health and hands (when working without gloves).
  • Limited in use for the facade.

The benefits of this kind of material actually outweigh the drawbacks by a wide margin.

Sodium silicate, sometimes referred to as liquid glass, is a multipurpose addition to concrete that has several advantages. The strength, longevity, and water resistance of concrete can all be greatly improved by adding liquid glass to the mixture. This makes it a great option for building projects that need extra moisture protection or are subjected to harsh environmental conditions.

The ability to use liquid glass in concrete to increase the final product’s compressive strength is one of its main benefits. As a result, the structure becomes stronger and more resilient, able to withstand higher loads and stresses. Liquid glass also increases the concrete’s resistance to abrasion and chemicals, extending its lifespan and lowering maintenance costs.

But, there are a few disadvantages to take into account when using liquid glass. Inadequate proportioning may result in a quicker setting time, which will make working with the concrete more difficult. To achieve the best results, careful measurement and mixing are needed. Furthermore, liquid glass may be more expensive than other additives, which could have an effect on a project’s overall budget.

The recommended ratios and mixing schedule must be adhered to when preparing liquid glass for use in concrete. Generally, 5–10% of the cement weight should be added to the liquid glass. When the ingredients are well combined, the liquid glass is dispersed uniformly throughout the concrete mixture, resulting in reliable performance and advantages.

In conclusion, liquid glass is a useful addition that improves the qualities of concrete. For a variety of construction applications, its capacity to increase strength, durability, and water resistance makes it a well-liked option. To prevent future issues with scheduling and expenses, it is crucial to carefully control its use. You can get the desired results and build a more durable and resilient concrete structure by adhering to the recommended proportions and mixing instructions.
