What exactly is a concrete release agent?

A concrete release agent is a material applied to the development design just before the concrete is poured so that the template will not stick to to the concrete area right after putting, is just not effortless to dismantle the cast or impacts the finish of the concrete surface. Its main role in the template and the concrete area to form a film that will be separated from the two is additionally called an separation agent.

A water-based release agent is surely an crucial auxiliary within the release agent and can alter the water-based release agent circulation and levelling; its main characteristic is stability to microorganisms and enzymes, which can reduce the price of raw materials. A water-based form release agent is utilized in casts and products functional processing ingredients; in the rubber, plastic, and Jinsu processing market, manufacturing form products are not just in order to let the cast release to improve productivity and lengthen the life of the form make use of. And can make the merchandise clean, size qualified, and decrease the creation of scrap, which can be an essential additional vital to forms and products – concrete additive.

Concrete release agent plays an crucial role inside modern building development; its primary role is to form a layer of separation motion picture between the design and the concrete surface to ensure that the template doesn’t adhere to the concrete area in order that it is simpler to take apart the mould following putting and to maintain the end of the concrete surface. Here, we will introduce the sorts, qualities, use and program of concrete release agent at length.

Kinds of concrete release agent

Concrete release agents can be divided into many sorts based on different classification methods, and the frequent classification strategies are the following:

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

Features of Concrete release agent

A concrete release agent is additionally referred to as a concrete separation agent or mould release lubricant. It is actually a sort of compound coated on the inner wall of the formwork to play the part of lubricating and isolation so that the concrete may 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 conventional release materials motor oil or waste motor oil, the release agent has the benefits of simple release, no pollution of the concrete surface, no corrosion of the template, easy to paint, low price and etc. However, not all sorts of concrete release representatives with a variety of components made of templates are suitable for different materials of the template and different construction 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 qualities:
Good remoteness efficiency: concrete release agent can create a dense remoteness motion picture between the formwork and the concrete surface, successfully avoiding the formwork from bonding with the concrete area and facilitating the demolding.

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

Excellent anti-adhesion overall performance: concrete release brokers can efficiently prevent the formwork from bonding with the concrete area, avoiding the formwork from damaging the concrete area when taking apart the formwork.

Excellent waterproof performance: 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 enhancing the service life of the formwork.

Easy 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 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 area.

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

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 construction 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 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 improve 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 construction projects.

In conclusion, concrete release agent, as an essential 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 growth of the development industry.
