What is a concrete release agent?

A concrete release agent is a material applied to the development template prior to the concrete is poured so the design doesn’t stick to the concrete area right after pouring, is not easy to take apart the mould or affects the end of the concrete surface. Its primary role within the template and the concrete covering to form a film that is going to be separated from the two is also referred to as an isolation agent.

A water-based release agent is an essential ancillary in the release agent and can alter the water-based release agent stream and levelling; its principal feature is stability to microorganisms and enzymes, which can lower the price of raw materials. A water-based mould release agent is utilized in casts and products functional processing ingredients; in the rubber, plastic, and Jinsu processing market, manufacturing cast items are not only to be able to let the form release to boost productivity and prolong the life of the form make use of. And can make the merchandise thoroughly clean, size qualified, and reduce the creation of scrap, which is an crucial additive vital to moulds and goods – concrete release agent.

Concrete release agent plays an important role within modern building building; its principal role would be to form a layer of remoteness motion picture between the template and the concrete area in order that the template will not adhere to the concrete covering in order that it is easier to dismantle the form following putting and to maintain the complete of the concrete area. Here, we will introduce the kinds, qualities, utilization and program of concrete release agent in more detail.

Kinds of concrete release agent

Concrete release representatives can be divided into several types in accordance with different category strategies, and the common grouping strategies are the subsequent:

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

Qualities of Concrete release agent

A concrete release agent is also called a concrete remoteness agent or mould release lubricant. It is actually a sort of material coated on the inner wall of the formwork to play the role of lubricating and remoteness to ensure that the concrete could be effortlessly detached from the formwork when dismantling the formwork, and the shape of the concrete could be kept intact and undamaged. Compared with the conventional release materials motor oil or waste motor oil, the release agent has the benefits of effortless release, no pollution of the concrete surface, no corrosion of the template, simple to paint, low price and and so forth. However, not all kinds of concrete release brokers with a selection of components made of templates are suitable for different materials 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 next qualities:
Good isolation overall performance: concrete release agent can develop a dense remoteness motion picture between the formwork and the concrete surface, successfully avoiding the formwork from bonding with the concrete covering and facilitating the dismantling.

Great lubrication performance: concrete release agent has good lubricating efficiency, which can lower the chaffing between the formwork and concrete surface, decrease the resistance during pouring and improve the construction productivity.

Great anti-adhesion efficiency: concrete release agents can effectively prevent the formwork from bonding with the concrete area, avoiding the formwork from damaging the concrete area when dismantling the formwork.

Great waterproof performance: concrete release agent has good waterproof performance, which can effectively stop moisture from penetrating between the formwork and concrete, steering clear of 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 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 area, 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 building projects, mainly including the following aspects:

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