What is actually a concrete release agent?
A concrete release agent is actually a material put on the development template just before the concrete is poured so that the template does not adhere to the concrete surface right after putting, is just not effortless to dismantle the cast or affects the end of the concrete area. Its main role within the template and the concrete surface to develop a film that will probably be separated from the two can also be called an remoteness agent.
A water-based release agent is surely an crucial ancillary within the release agent and can modify the water-based release agent stream and levelling; its principal attribute is actually stability to microorganisms and enzymes, which can reduce the expense of raw materials. A water-based form release agent is used in forms and items functional processing ingredients; in the rubber, plastic, and Jinsu processing business, manufacturing form goods are not just so as to let the mould release to improve productivity and lengthen the life of the form make use of. And can make the merchandise thoroughly clean, size qualified, and reduce the creation of scrap, which can be an essential supplementary essential to casts and products – Water-based Concrete Release Agent.
Concrete release agent plays an essential role within modern building building; its primary role would be to create a layer of separation movie between the design and the concrete surface to ensure that the template does not adhere to the concrete surface to ensure that it is easier to take down the cast following flowing and to maintain the complete of the concrete covering. Here, we will introduce the sorts, qualities, utilization and application of concrete release agent in detail.
Kinds of concrete release agent
Concrete release agents can be divided into many types in accordance with different classification methods, and the frequent classification strategies are the following:
- According to the opportunity of use: it can be divided into concrete release agent for building, concrete release agent for bridges, concrete release agent for tunnels and so on.
- According to the composition: it can be divided into water-based concrete release agents, oil-based concrete release brokers, silicone oil concrete release brokers, etc.
- According to the utilization effect: it can be divided into ordinary concrete release brokers, simple to remove concrete release agents, high-gloss concrete release brokers and etc.
Features of Concrete release agent
A concrete release agent is also called a concrete isolation agent or mould release lubricant. It is actually a type of substance coated on the inner wall of the formwork to play the role of lubricating and remoteness so that the concrete could be easily detached from the formwork when dismantling the formwork, and the shape of the concrete may be kept intact and undamaged. Compared with the traditional release material motor oil or waste motor oil, the release agent has the positive aspects of effortless release, no pollution of the concrete surface, no corrosion of the template, simple to paint, low price and so on. However, not all kinds of concrete release agents with a array of components made of templates are suitable for different supplies of the template and different construction 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 next characteristics:
Good remoteness performance: concrete release agent can create a dense remoteness film between the formwork and the concrete surface, efficiently avoiding the formwork from bonding with the concrete covering and facilitating the dismantling.
Great lubrication efficiency: concrete release agent has good lubrication efficiency, which can lower the friction between the formwork and concrete area, decrease the resistance during pouring and boost the construction productivity.
Great anti-adhesion performance: concrete release representatives can successfully avoid the formwork from bonding with the concrete area, preventing the formwork from damaging the concrete surface when taking apart the formwork.
Great waterproof performance: concrete release agent has good waterproof efficiency, which can successfully stop moisture from penetrating between the formwork and concrete, steering clear of deformation of the formwork by moisture and improving 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 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 area.
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 surface of the formwork should be knocked gently to separate the formwork from the concrete area 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 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 development projects, mainly including the following aspects:
Reinforced concrete structure: In the construction of a reinforced concrete structure, concrete release brokers 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 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 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 construction 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 development project and provide a strong guarantee for the development of the construction industry.
