What is a concrete release agent?

A concrete release agent is actually a substance placed on the building template prior to the concrete is added so that the design doesn’t adhere to the concrete area right after pouring, is not effortless to take apart the form or influences the complete of the concrete covering. Its principal role inside the template and the concrete covering to form a film that will probably be separated from the two is additionally called an separation agent.

A water-based release agent is an crucial ancillary in the release agent and can change the water-based release agent stream and levelling; its principal feature is stability to microorganisms and enzymes, which can decrease the expense of raw materials. A water-based mould release agent is utilized in casts and goods functional processing supplements; in the rubber, plastic, and Jinsu processing industry, manufacturing mould goods are not just so as to let the cast release to boost productivity and prolong the life of the form use. And can make the product clear, size qualified, and lower the creation of scrap, that is an important additional important to moulds and products – Water-based Concrete Release Agent.

Concrete release agent plays an important role inside modern building construction; its principal role would be to create a layer of separation motion picture between the design and the concrete covering so that the template will not stick to to the concrete area to ensure that it is easier to dismantle the cast after pouring and to maintain the end of the concrete area. Here, we will unveil the kinds, characteristics, utilization and program of concrete release agent at length.

Kinds of concrete release agent

Concrete release representatives can be divided into numerous types according to different category methods, and the common grouping methods are the following:

  • According to 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 formula of: it can be divided into water-based concrete release representatives, petroleum-based concrete release brokers, silicone oil concrete release brokers, etc.
  • According to the the utilization effect: it can be divided into ordinary concrete release agents, easy-to-remove concrete release representatives, high-gloss concrete release brokers and so on.

Features of Concrete release agent

A concrete release agent is also referred to as a concrete separation agent or mould release lubricant. It is actually a sort of material coated on the inner wall of the formwork to play the function of lubrication and remoteness in order that the concrete could be effortlessly detached from the formwork when dismantling the formwork, and the shape of the concrete may be kept intact and undamaged. Compared with the standard release material motor oil or waste motor oil, the release agent has the advantages of effortless release, no pollution of the concrete surface, no corrosion of the template, easy to paint, low cost and and so forth. However, not all sorts of concrete release brokers with a variety of materials made of templates are suitable for different components of the template and different building problems and finish requirements of the concrete must be selected for the ideal release agent in order to receive good results.

As an important construction auxiliary material, concrete release agent has the subsequent qualities:
Good separation performance: concrete release agent can develop a dense isolation motion picture between the formwork and the concrete surface, effectively stopping the formwork from bonding with the concrete surface and facilitating the removing.

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

Good anti-adhesion performance: concrete release brokers can successfully prevent the formwork from bonding with the concrete covering, steering clear of the formwork from damaging the concrete covering when dismantling the formwork.

Good waterproof efficiency: concrete release agent has good waterproof efficiency, which can efficiently prevent 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 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 surface.

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 surface 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 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 building projects, mainly including the following aspects:

Reinforced concrete structure: In the development of a reinforced concrete structure, concrete release representatives can be used for formwork isolation, avoiding 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 surface, 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 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 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 crucial construction auxiliary material, plays an indispensable role in modern development 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 development of the development industry.
