What is a concrete release agent?

A concrete release agent is definitely a compound applied to the development template before the concrete is poured in order that the template does not stick to the concrete surface following pouring, isn’t effortless to take down the mould or influences the end of the concrete area. Its primary role in the design and the concrete covering to create a motion picture that will be separated from the two is also referred to as an separation agent.

A water-based release agent is an important auxiliary within the release agent and can modify the water-based release agent circulation and levelling; its primary feature is stability to microorganisms and enzymes, which can reduce the expense of raw materials. A water-based mould release agent is utilized in moulds and products functional processing additives; in the rubber, plastic, and Jinsu processing industry, manufacturing cast items aren’t just so as to let the form release to enhance productivity and lengthen the life of the mould make use of. And can make the item thoroughly clean, size qualified, and lower the generation of scrap, which can be an crucial additional essential to forms and items – Water-based Concrete Release Agent.

Concrete release agent plays an important role in modern building building; its primary role would be to form a layer of isolation film between the design and the concrete area so that the template will not adhere to the concrete area so that it is much easier to dismantle the mould right after putting and to maintain the end of the concrete covering. Here, we will present the sorts, qualities, use and application of concrete release agent at length.

Types of concrete release agent

Concrete release brokers can be divided into many types in accordance with different classification methods, and the frequent category methods are as follows:

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

Qualities of Concrete release agent

A concrete release agent can also be called a concrete isolation agent or mould release lubricant. It is really a sort of compound coated on the inner wall of the formwork to play the function of lubrication and separation to ensure that the concrete can be smoothly detached from the formwork when taking down the formwork, and the form of the concrete can be kept intact and undamaged. Compared with the standard release substance motor oil or waste motor oil, the release agent has the benefits of easy release, no pollution of the concrete surface, no corrosion of the template, simple to paint, low cost and and so forth. However, not all kinds of concrete release brokers with a array of components made of templates are suitable for different components of the template and different development circumstances and finish requirements of the concrete must be selected for the suitable release agent in order to receive good results.

As an crucial construction auxiliary material, concrete release agent has the following features:
Good isolation overall performance: concrete release agent can create a dense isolation movie between the formwork and the concrete surface, efficiently stopping the formwork from bonding with the concrete surface and facilitating the removing.

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

Excellent anti-adhesion efficiency: concrete release brokers can efficiently avoid the formwork from bonding with the concrete area, steering clear of the formwork from damaging the concrete covering when dismantling the formwork.

Good waterproof 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 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 area gradually. In case of tight bonding between the formwork and the concrete area, tools can be used appropriately to assist in the taking apart.

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 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 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 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 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 building projects.

In conclusion, concrete release agent, as an important 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 enhance the construction efficiency and quality of the construction project and provide a strong guarantee for the growth of the construction industry.
