What is a concrete release agent?

A concrete release agent is actually a compound put on the development design before the concrete is added so that the design doesn’t adhere to the concrete area after pouring, is just not simple to take apart the mould or impacts the finish of the concrete covering. Its principal role within the template and the concrete surface to form a movie that is going to be separated from the two is additionally known as an isolation agent.

A water-based release agent is definitely an crucial supplementary within the release agent and can modify the water-based release agent stream and levelling; its principal characteristic is stability to microorganisms and enzymes, which can decrease the cost of raw materials. A water-based form release agent is used in forms and goods functional processing additives; in the rubber, plastic, and Jinsu processing industry, manufacturing mould goods aren’t just so as to let the form release to improve productivity and extend the life of the cast make use of. And can make the product clean, size qualified, and reduce the technology of scrap, which is an important additive vital to forms and goods – concrete additive.

Concrete release agent plays an crucial role inside modern building building; its main role is to form a layer of isolation film between the design and the concrete covering to ensure that the template does not stick to the concrete covering to ensure that it is much easier to dismantle the mould right after pouring and to maintain the finish of the concrete covering. Here, we will present the types, qualities, utilization and application of concrete release agent at length.

Kinds of concrete release agent

Concrete release brokers can be divided into several types in accordance with different grouping techniques, and the common category strategies 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 launch agent for tunnels and so on.
• According to the composition: it can be divided into water-based concrete release brokers, petroleum-based concrete release brokers, silicone oil concrete release representatives, etc.
• According to the effect of use: it can be divided into ordinary concrete release agents, easy-to-remove concrete release agents, high-gloss concrete release brokers and so on.

Characteristics of Concrete release agent

A concrete release agent can also be called a concrete separation agent or mould release lubricant. It is a type of compound coated on the inner wall of the formwork to play the function of lubricating and separation so that the concrete could be smoothly detached from the formwork when taking apart the formwork, and the form of the concrete could be kept intact and undamaged. Compared with the conventional release material motor oil or waste motor oil, the release agent has the advantages of simple release, no pollution of the concrete surface, no corrosion of the template, easy to paint, low cost and and so forth. However, not all sorts of concrete release agents with a variety of components made of templates are suitable for different materials of the template and different development conditions and finish requirements of the concrete must be selected for the suitable release agent in order to receive good results.

As an important construction auxiliary material, concrete release agent has the next features:
Good separation performance: concrete release agent can create a dense separation movie between the formwork and the concrete covering, successfully avoiding the formwork from bonding with the concrete covering and facilitating the demolding.

Great lubrication performance: concrete release agent has good lubricating overall performance, which can lower the rubbing between the formwork and concrete surface, lower the resistance during pouring and enhance the construction efficiency.

Great anti-adhesion efficiency: concrete release agents can effectively avoid the formwork from bonding with the concrete area, avoiding the formwork from damaging the concrete surface when dismantling the formwork.

Good waterproof overall performance: concrete release agent has good waterproof overall performance, which can successfully prevent moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and enhancing the service life of the formwork.

Effortless to use and safe: concrete release agent is simple 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 oil-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 dismantling 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 surface gradually. In case of tight bonding between the formwork and the concrete area, tools can be used appropriately to assist in the dismantling.

Clean up the template: after dismantling 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 building projects, mainly including the following aspects:

Reinforced concrete structure: In the development of a reinforced concrete structure, concrete release brokers can be used for formwork isolation, stopping formwork from bonding with concrete and enhancing 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 area, 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 area and boost 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 enhance 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 development projects.

In conclusion, concrete release agent, as an essential 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 boost the construction efficiency and quality of the building project and provide a strong guarantee for the growth of the development industry.
