What is actually a concrete release agent?

A concrete release agent is actually a material placed on the construction design just before the concrete is added in order that the template does not stick to to the concrete surface right after flowing, is not effortless to take down the cast or influences the finish of the concrete surface. Its main role within the design and the concrete surface to form a film that is going to be separated from the two is also referred to as an isolation agent.

A water-based release agent is an essential supplementary within the release agent and can alter the water-based release agent stream and levelling; its primary attribute is actually stability to microorganisms and enzymes, which can lower the price of raw materials. A water-based cast release agent is utilized in casts and goods functional processing supplements; in the rubber, plastic, and Jinsu processing market, manufacturing mould products are not only to be able to let the mould release to enhance productivity and extend the life of the cast utilize. And can make the item thoroughly clean, size qualified, and reduce the creation of scrap, that is an crucial supplementary vital to moulds and goods – concrete additive.

Concrete release agent plays an important role inside modern building construction; its primary role would be to form a layer of separation movie between the template and the concrete surface to ensure that the template does not stick to to the concrete surface in order that it is easier to dismantle the cast after flowing and to maintain the end of the concrete covering. Here, we will introduce the types, features, use and program of concrete release agent in detail.

Sorts of concrete release agent

Concrete release agents can be divided into numerous types based on different classification techniques, and the frequent grouping strategies are as follows:

• According to the opportunity of use: it can be divided into concrete release agent for development, concrete release agent for bridges, concrete release agent for tunnels and etc.
• According to the composition: it can be divided into water-based concrete release agents, petroleum-based concrete release agents, silicone oil concrete release agents, etc.
• According to the use effect: it can be divided into ordinary concrete release representatives, an easy task to remove concrete release agents, high-gloss concrete release representatives and so on.

Features of Concrete release agent

A concrete release agent is also referred to as a concrete remoteness agent or mould release lubricant. It is actually a kind of substance coated on the inner wall of the formwork to play the part of lubricating and isolation in order that the concrete could be effortlessly detached from the formwork when taking apart the formwork, and the condition of the concrete could be kept intact and undamaged. Compared with the standard release substance motor oil or waste motor oil, the release agent has the benefits of simple release, no pollution of the concrete covering, no corrosion of the template, easy to paint, low value and and so forth. However, not all types of concrete release representatives with a selection of materials made of templates are suitable for different components of the template and different construction conditions 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 subsequent qualities:
Good separation overall performance: concrete release agent can develop a dense separation movie between the formwork and the concrete covering, efficiently stopping the formwork from bonding with the concrete covering and facilitating the removing.

Great lubrication efficiency: concrete release agent has good lubricating efficiency, which can reduce the rubbing between the formwork and concrete area, reduce the resistance during pouring and enhance the construction effectiveness.

Excellent anti-adhesion performance: concrete release representatives can successfully stop the formwork from bonding with the concrete covering, steering clear of the formwork from damaging the concrete covering when dismantling the formwork.

Excellent waterproof efficiency: concrete release agent has good waterproof performance, which can effectively stop moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and improving the service life of the formwork.

Effortless 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 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 taking down 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 area gradually. In case of tight bonding between the formwork and the concrete surface, tools can be used appropriately to assist in the taking down.

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 development projects, mainly including the following aspects:

Reinforced concrete structure: In the building of a reinforced concrete structure, concrete release representatives can be used for formwork isolation, stopping 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 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 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 boost 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 agents 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 development 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 construction project and provide a strong guarantee for the advancement of the development industry.
