What is a concrete release agent?
A concrete release agent is definitely a compound placed on the construction design prior to the concrete is poured so that the template doesn’t adhere to the concrete surface following pouring, is just not simple to take down the cast or impacts the complete of the concrete area. Its principal role inside the template and the concrete surface to create a film that is going to be separated from the two is also referred to as an separation agent.
A water-based release agent is an important ancillary within the release agent and can change the water-based release agent circulation and levelling; its principal feature is definitely stability to microorganisms and enzymes, which can reduce the expense of raw materials. A water-based mould release agent is used in forms and items functional processing supplements; in the rubber, plastic, and Jinsu processing industry, manufacturing cast items are not only to be able to let the form release to improve productivity and extend the life of the form utilize. And can make the item clean, size qualified, and lower the technology of scrap, that is an essential additional vital to casts and items – Water-based Concrete Release Agent.
Concrete release agent plays an crucial role inside modern building construction; its main role is to create a layer of remoteness film between the template and the concrete covering in order that the design doesn’t stick to to the concrete area in order that it is much easier to take down the cast following putting and to maintain the finish of the concrete covering. Here, we will unveil the sorts, qualities, use and use of concrete release agent in more detail.
Sorts of concrete release agent
Concrete release representatives can be divided into several kinds according to different classification techniques, and the common grouping strategies are the subsequent:
- According to the the opportunity of use: it can be divided into concrete release agent for building, 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 brokers, petroleum-based concrete release representatives, silicone oil concrete release agents, etc.
- According to the utilization effect: it can be divided into ordinary concrete release representatives, simple to remove concrete release agents, high-gloss concrete release agents and so on.
Qualities of Concrete release agent
A concrete release agent is also known as a concrete separation agent or mould release lubricant. It is actually a kind of material coated on the inner wall of the formwork to play the role of lubrication and separation in order that the concrete can be easily detached from the formwork when taking down 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 benefits of simple release, no pollution of the concrete surface, no corrosion of the template, easy to paint, low cost and so on. However, not all sorts of concrete release brokers with a selection of components made of templates are suitable for different materials of the template and different construction problems and finish requirements of the concrete must be selected for the appropriate release agent in order to receive good results.
As an important construction auxiliary material, concrete release agent has the following qualities:
Good remoteness overall performance: concrete release agent can develop a dense remoteness film between the formwork and the concrete area, successfully preventing the formwork from bonding with the concrete area and facilitating the demolding.
Excellent lubrication overall performance: concrete release agent has good lubrication overall performance, which can lower the chaffing between the formwork and concrete surface, decrease the resistance during pouring and enhance the construction efficiency.
Good anti-adhesion efficiency: concrete release agents can successfully avoid the formwork from bonding with the concrete covering, avoiding the formwork from damaging the concrete covering when taking apart the formwork.
Great waterproof performance: concrete release agent has good waterproof overall 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 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 surface of the formwork should be knocked gently to separate the formwork from the concrete surface 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 development projects, mainly including the following aspects:
Reinforced concrete structure: In the building of a reinforced concrete structure, concrete release agents can be used for formwork isolation, stopping 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 covering 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 building 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 enhance the construction efficiency and quality of the construction project and provide a strong guarantee for the advancement of the construction industry.
