What is actually a concrete release agent?

A concrete release agent is actually a substance placed on the development design prior to the concrete is added in order that the template doesn’t stick to to the concrete covering right after pouring, is not effortless to dismantle the mould or impacts the complete of the concrete surface. Its primary role in the template and the concrete covering to develop a film that will be separated from the two is also known as an remoteness agent.

A water-based release agent is surely an essential supplementary inside the release agent and can alter the water-based release agent stream and levelling; its main feature is stability to microorganisms and enzymes, which can reduce the price of raw materials. A water-based form release agent is utilized in forms and products functional processing additives; in the rubber, plastic, and Jinsu processing industry, manufacturing cast items are not only so as to let the mould release to improve productivity and prolong the life of the mould utilize. And can make the item thoroughly clean, size qualified, and lower the technology of scrap, that is an crucial supplementary important to forms and goods – concrete release agent.

Concrete release agent plays an essential role within modern building building; its primary role is to form a layer of isolation movie between the template and the concrete surface in order that the template does not stick to to the concrete area so that it is easier to dismantle the cast following putting and to maintain the end of the concrete covering. Here, we will present the types, characteristics, usage and program of concrete release agent in more detail.

Sorts of concrete release agent

Concrete release representatives can be divided into many types in accordance with different classification methods, and the typical grouping techniques are the subsequent:

• According to the scope of use: it can be divided into concrete release agent for building, concrete release agent for bridges, concrete discharge agent for tunnels and etc.
• According to the composition of: it can be divided into water-based concrete release agents, petroleum-based concrete release representatives, silicone oil concrete release representatives, etc.
• According to the utilization effect: it can be divided into ordinary concrete release brokers, simple to remove concrete release representatives, high-gloss concrete release agents and so on.

Characteristics of Concrete release agent

A concrete release agent is also called a concrete remoteness agent or mould release lubricant. It is really a sort of compound coated on the inner wall of the formwork to play the part of lubricating and remoteness so that the concrete may be easily detached from the formwork when taking down the formwork, and the form of the concrete may be kept intact and undamaged. Compared with the traditional release materials motor oil or waste motor oil, the release agent has the advantages of simple release, no pollution of the concrete covering, no corrosion of the template, simple to paint, low cost and so on. However, not all types of concrete release agents with a array of materials made of templates are suitable for different supplies of the template and different development circumstances and finish requirements of the concrete must be selected for the ideal release agent in order to receive good results.

As an crucial construction auxiliary material, concrete release agent has the next characteristics:
Good isolation efficiency: concrete release agent can develop a dense separation motion picture between the formwork and the concrete surface, efficiently stopping the formwork from bonding with the concrete area and facilitating the dismantling.

Great lubrication performance: concrete release agent has good lubrication efficiency, which can decrease the chaffing between the formwork and concrete area, reduce the resistance during pouring and improve the construction effectiveness.

Excellent anti-adhesion overall performance: concrete release agents can successfully stop the formwork from bonding with the concrete surface, preventing the formwork from damaging the concrete surface when taking down the formwork.

Great waterproof overall performance: concrete release agent has good waterproof efficiency, which can effectively avoid moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and increasing the service life of the formwork.

Easy to use and safe: concrete release agent is effortless to use; you only need to apply a layer evenly on the formwork; at the same time, it is safe and environmentally friendly and will not pollute the human body and the environment.

When using a concrete release agent, the following steps should be followed:

Prepare tools: concrete release agent is usually sprayed or brushed for construction. You need to prepare construction tools such as a sprayer or brush.

Choose the right release agent: According to the different environments, choose the right concrete release agent, such as indoor use can choose a water-based concrete release agent, and outdoor use can choose an petroleum-based concrete release agent.

Apply the release agent: Pour the appropriate amount of release agent into the sprayer or container, and then evenly spray or brush on the formwork to ensure that each part is coated in place.

Air drying: After application, wait for a period of time to allow the release agent to dry naturally. Generally, it takes 10-20 minutes, depending on the environment.

Pouring concrete: After the release agent is completely air-dried, the concrete can be poured. During the pouring process, care should be taken to avoid air bubbles or voids between the formwork and the concrete covering.

Demolding: Demolding can be carried out after the concrete reaches the strength of demolding. When taking apart the formwork, the connectors at the edge of the formwork should be dismantled first, and then the surface of the formwork should be knocked gently to separate the formwork from the concrete covering gradually. In case of tight bonding between the formwork and the concrete surface, tools can be used appropriately to assist in the dismantling.

Clean up the template: after taking down the template, the template should be cleaned up to remove the residual concrete and mould release agent. After cleaning, it can be used for the next time.

Application areas of concrete release agent:

Concrete release agent is widely used in all kinds of development projects, mainly including the following aspects:

Reinforced concrete structure: In the development of a reinforced concrete structure, concrete release representatives can be used for formwork isolation, avoiding formwork from bonding with concrete and increasing construction efficiency and quality.

Road construction: in road construction, the concrete release agent can be used to isolate the bond layer between the road formwork and concrete covering, to avoid road bubbles, hollow drums and other problems.

Bridge project: In a bridge project, a concrete release agent can be used to isolate the bond layer between the bridge formwork and the concrete surface and enhance the construction quality of the bridge pier and abutment.

Tunnelling project: In the tunnelling project, a concrete release agent can be used to isolate the bond layer between tunnel formwork and shotcrete surface to improve the quality and safety of tunnel construction.

Nuclear power project: In nuclear power project, a concrete release agent can be used to isolate the bond layer between the shell of nuclear power equipment and internal components to ensure the safety and stability of the equipment.

Other fields: concrete release brokers can also be widely used in water conservancy projects, wharf projects, airport projects and other fields to provide effective formwork isolation protection measures for various construction projects.

In conclusion, concrete release agent, as an crucial construction auxiliary material, plays an indispensable role in modern construction projects. By choosing the right type, the correct use method and a reasonable application field, can effectively improve the construction efficiency and quality of the building project and provide a strong guarantee for the development of the development industry.
