What exactly is a concrete release agent?

A concrete release agent is actually a substance put on the development template just before the concrete is put so the design does not adhere to the concrete surface right after flowing, is not simple to take apart the form or affects the finish of the concrete area. Its principal role inside the template and the concrete area to develop a movie that is going to be separated from the two is additionally known as an isolation agent.

A water-based release agent is surely an crucial auxiliary within the release agent and can modify the water-based release agent stream and levelling; its main feature is definitely stability to microorganisms and enzymes, which can decrease the expense of raw materials. A water-based form release agent is utilized in moulds and products functional processing supplements; in the rubber, plastic, and Jinsu processing business, manufacturing cast goods aren’t just in order to let the cast release to improve productivity and lengthen the life of the form use. And can make the product clear, size qualified, and decrease the technology of scrap, which can be an important additional essential to moulds and items – concrete additive.

Concrete release agent plays an essential role inside modern building building; its main role is to create a layer of remoteness movie between the template and the concrete area in order that the design doesn’t stick to to the concrete surface so that it is much easier to take down the cast following flowing and to maintain the end of the concrete area. Here, we will introduce the sorts, qualities, utilization and program of concrete release agent in more detail.

Kinds of concrete release agent

Concrete release brokers can be divided into many kinds in accordance with different category strategies, and the common classification 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 discharge agent for tunnels and and so forth.
• According to the formula of: it can be divided into water-based concrete release brokers, petroleum-based concrete release representatives, silicone oil concrete release brokers, etc.
• According to the utilization effect: it can be divided into ordinary concrete release brokers, simple to remove concrete release agents, high-gloss concrete release agents and etc.

Features of Concrete release agent

A concrete release agent can also be known as a concrete separation agent or mould release lubricant. It is really a kind of compound coated on the inner wall of the formwork to play the role of lubrication and isolation so that the concrete could be effortlessly detached from the formwork when dismantling the formwork, and the condition of the concrete may be kept intact and undamaged. Compared with the conventional release substance motor oil or waste motor oil, the release agent has the positive aspects of effortless release, no pollution of the concrete area, no corrosion of the template, simple to paint, low cost and so on. However, not all types of concrete release representatives with a variety of supplies made of templates are suitable for different components of the template and different building circumstances and finish requirements of the concrete must be selected for the ideal release agent in order to receive good results.

As an important construction auxiliary material, concrete release agent has the subsequent characteristics:
Good separation efficiency: concrete release agent can develop a dense isolation film between the formwork and the concrete surface, efficiently stopping the formwork from bonding with the concrete surface and facilitating the demolding.

Excellent lubrication efficiency: concrete release agent has good lubrication efficiency, which can reduce the rubbing between the formwork and concrete surface, lower the resistance during pouring and improve the construction efficiency.

Good anti-adhesion overall performance: concrete release brokers can effectively stop the formwork from bonding with the concrete area, avoiding the formwork from damaging the concrete area when taking down the formwork.

Good waterproof efficiency: concrete release agent has good waterproof performance, which can effectively avoid moisture from penetrating between the formwork and concrete, avoiding deformation of the formwork by moisture and enhancing 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 dismantling 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 covering gradually. In case of tight bonding between the formwork and the concrete covering, tools can be used appropriately to assist in the taking down.

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 building of a reinforced concrete structure, concrete release agents can be used for formwork isolation, avoiding formwork from bonding with concrete and improving 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 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 development projects.

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