What is actually a concrete release agent?

A concrete release agent is definitely a substance applied to the construction template before the concrete is poured so the template doesn’t stick to to the concrete covering after flowing, is not effortless to dismantle the cast or influences the finish of the concrete covering. Its main role in the design and the concrete area to develop a movie that will be separated from the two can also be known as an separation agent.

A water-based release agent is an essential supplementary in the release agent and can change the water-based release agent flow and levelling; its main attribute is actually stability to microorganisms and enzymes, which can reduce the expense of raw materials. A water-based cast release agent is used in moulds and items functional processing ingredients; in the rubber, plastic, and Jinsu processing industry, manufacturing cast goods aren’t just so as to let the mould release to enhance productivity and extend the life of the form use. And can make the merchandise clear, size qualified, and decrease the generation of scrap, that is an crucial supplementary essential to forms and products – Water-based Concrete Release Agent.

Concrete release agent plays an crucial role inside modern building development; its main role is always to form a layer of remoteness movie between the template and the concrete area to ensure that the template will not stick to to the concrete surface so that it is much easier to dismantle the mould right after flowing and to maintain the finish of the concrete covering. Here, we will introduce the types, qualities, use and application of concrete release agent at length.

Types of concrete release agent

Concrete release agents can be divided into numerous types according to different classification methods, and the common grouping strategies are as follows:

• According to the the scope of use: it can be divided into concrete release agent for development, concrete release agent for bridges, concrete release agent for tunnels and etc.
• According to the formula of: it can be divided into water-based concrete release brokers, 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 agents, an easy task to remove concrete release agents, high-gloss concrete release agents and so on.

Qualities of Concrete release agent

A concrete release agent is also referred to as a concrete remoteness agent or mould release lubricant. It is a sort of compound coated on the inner wall of the formwork to play the role of lubrication and isolation so that the concrete may be effortlessly detached from the formwork when dismantling 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 positive aspects of simple release, no pollution of the concrete area, no corrosion of the template, easy to paint, low cost and and so forth. However, not all kinds of concrete release brokers with a selection of materials made of templates are suitable for different materials of the template and different development conditions and finish requirements of the concrete must be selected for the appropriate release agent in order to receive good results.

As an crucial construction auxiliary material, concrete release agent has the subsequent characteristics:
Good separation efficiency: concrete release agent can develop a dense separation movie between the formwork and the concrete covering, efficiently preventing the formwork from bonding with the concrete covering and facilitating the removing.

Good lubrication overall performance: concrete release agent has good lubricating overall performance, which can decrease the chaffing between the formwork and concrete covering, reduce the resistance during pouring and improve the construction efficiency.

Great anti-adhesion efficiency: concrete release representatives can successfully prevent the formwork from bonding with the concrete area, avoiding the formwork from damaging the concrete surface when taking down the formwork.

Good waterproof performance: concrete release agent has good waterproof overall performance, which can successfully avoid moisture from penetrating between the formwork and concrete, avoiding deformation of the formwork by moisture and enhancing the service life of the formwork.

Effortless 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 surface.

Demolding: Demolding can be carried out after the concrete reaches the strength of demolding. When taking apart 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 surface, tools can be used appropriately to assist in the taking down.

Clean up the template: after taking down 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 building projects, mainly including the following aspects:

Reinforced concrete structure: In the construction of a reinforced concrete structure, concrete release agents can be used for formwork isolation, preventing 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 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 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 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 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 essential construction auxiliary material, plays an indispensable role in modern building projects. By choosing the right sort, the correct use method and a reasonable application field, can effectively improve the construction efficiency and quality of the construction project and provide a strong guarantee for the advancement of the development industry.
