What exactly is a concrete release agent?

A concrete release agent is actually a substance placed on the development template just before the concrete is added so the template will not stick to the concrete area right after flowing, isn’t effortless to take apart the mould or impacts the finish of the concrete covering. Its principal role in the template and the concrete area to develop a film that will probably be separated from the two is additionally known as an remoteness agent.

A water-based release agent is an crucial auxiliary inside the release agent and can alter the water-based release agent circulation and levelling; its primary feature is definitely stability to microorganisms and enzymes, which can reduce the expense of raw materials. A water-based mould release agent is used in casts and goods functional processing supplements; in the rubber, plastic, and Jinsu processing business, manufacturing cast products are not only in order to let the cast release to improve productivity and lengthen the life of the mould make use of. And can make the item clear, size qualified, and reduce the technology of scrap, which can be an crucial additional important to forms and goods – Water-based Concrete Release Agent.

Concrete release agent plays an crucial role inside modern building construction; its primary role is always to develop a layer of isolation motion picture between the template and the concrete area so that the template doesn’t stick to to the concrete area so that it is simpler to take down the cast after flowing and to maintain the complete of the concrete covering. Here, we will unveil the types, qualities, utilization and use of concrete release agent in detail.

Types of concrete release agent

Concrete release brokers can be divided into many sorts based on different category methods, and the typical grouping strategies are as follows:

• According to the scope of use: it can be divided into concrete release agent for building, 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 brokers, silicone oil concrete release brokers, etc.
• According to the use effect: it can be divided into ordinary concrete release agents, simple to remove concrete release brokers, high-gloss concrete release agents and so on.

Features of Concrete release agent

A concrete release agent can also be referred to as a concrete isolation agent or mould release lubricant. It is a kind of substance coated on the inner wall of the formwork to play the role of lubrication and isolation to ensure that the concrete could be easily detached from the formwork when taking down the formwork, and the condition of the concrete may be kept intact and undamaged. Compared with the traditional release material motor oil or waste motor oil, the release agent has the positive aspects of easy release, no pollution of the concrete area, no corrosion of the template, effortless to paint, low value and so on. However, not all sorts of concrete release agents with a selection of supplies made of templates are suitable for different components 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 essential construction auxiliary material, concrete release agent has the next qualities:
Good remoteness efficiency: concrete release agent can form a dense isolation movie between the formwork and the concrete covering, effectively stopping the formwork from bonding with the concrete covering and facilitating the removing.

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

Good anti-adhesion performance: concrete release representatives can successfully prevent the formwork from bonding with the concrete area, avoiding the formwork from damaging the concrete surface when dismantling the formwork.

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

Simple to use and safe: concrete release agent is easy 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 surface.

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 covering 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 covering, tools can be used appropriately to assist in the dismantling.

Clean up the template: after taking apart 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 construction 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, 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 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 covering and improve 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 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 building 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 building project and provide a strong guarantee for the development of the development industry.
