What is actually a concrete release agent?

A concrete release agent is a material applied to the building design before the concrete is poured so the template does not adhere to the concrete surface following flowing, isn’t simple to take apart the mould or influences the finish of the concrete surface. Its main role in the design and the concrete covering to create a movie that is going to be separated from the two is also referred to as an remoteness agent.

A water-based release agent is surely an essential auxiliary inside the release agent and can alter the water-based release agent circulation and levelling; its main feature is definitely stability to microorganisms and enzymes, which can reduce the price of raw materials. A water-based cast release agent is used in forms and items functional processing supplements; in the rubber, plastic, and Jinsu processing business, manufacturing cast products are not only so as to let the cast release to improve productivity and extend the life of the cast utilize. And can make the product thoroughly clean, size qualified, and reduce the creation of scrap, which is an important additional important to moulds and products – Water-based Concrete Release Agent.

Concrete release agent plays an crucial role in modern building development; its main role would be to form a layer of remoteness movie between the template and the concrete area in order that the template does not stick to to the concrete covering so that it is easier to take apart the mould after putting and to maintain the end of the concrete area. Here, we will unveil the sorts, features, use and application of concrete release agent in more detail.

Types of concrete release agent

Concrete release brokers can be divided into numerous sorts according to different grouping techniques, and the common category strategies are the subsequent:

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

Characteristics of Concrete release agent

A concrete release agent is additionally known as a concrete separation agent or mould release lubricant. It is really a kind of substance coated on the inner wall of the formwork to play the role of lubricating and isolation in order that the concrete could be smoothly detached from the formwork when taking apart the formwork, and the shape of the concrete may be kept intact and undamaged. Compared with the standard release materials 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, easy to paint, low cost and etc. However, not all kinds of concrete release representatives with a array of components made of templates are suitable for different materials of the template and different building conditions and finish requirements of the concrete must be selected for the appropriate release agent in order to receive good results.

As an essential construction auxiliary material, concrete release agent has the following qualities:
Good isolation efficiency: concrete release agent can form a dense remoteness film between the formwork and the concrete covering, successfully stopping the formwork from bonding with the concrete surface and facilitating the dismantling.

Good lubrication performance: concrete release agent has good lubrication overall performance, which can lower the friction between the formwork and concrete covering, lower the resistance during pouring and boost the construction productivity.

Good anti-adhesion efficiency: concrete release brokers can successfully avoid the formwork from bonding with the concrete area, steering clear of the formwork from damaging the concrete area when taking down the formwork.

Excellent waterproof overall performance: concrete release agent has good waterproof performance, which can efficiently prevent 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 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 taking down the formwork, the connectors at the edge of the formwork should be dismantled first, and then the area 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 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 construction projects, mainly including the following aspects:

Reinforced concrete structure: In the construction of a reinforced concrete structure, concrete release representatives 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 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 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 building projects. By choosing the right kind, 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 advancement of the construction industry.
