What exactly is a concrete release agent?
A concrete release agent is definitely a compound applied to the development template just before the concrete is poured so that the template does not stick to to the concrete area right after flowing, is not effortless to dismantle the cast or affects the complete of the concrete area. Its main role inside the template and the concrete covering to develop a movie that is going to be separated from the two is also known as an remoteness agent.
A water-based release agent is an essential auxiliary within the release agent and can alter the water-based release agent stream and levelling; its primary characteristic is actually stability to microorganisms and enzymes, which can lower the cost of raw materials. A water-based mould release agent is used in casts and items functional processing ingredients; in the rubber, plastic, and Jinsu processing market, manufacturing form products are not only in order to let the mould release to improve productivity and lengthen the life of the mould use. And can make the item clean, size qualified, and reduce the technology of scrap, which is an crucial supplementary essential to moulds and items – concrete additive.
Concrete release agent plays an essential role within modern building building; its primary role is to create a layer of separation film between the template and the concrete area so that the template does not stick to to the concrete covering so that it is easier to dismantle the mould right after pouring and to maintain the finish of the concrete covering. Here, we will present the sorts, qualities, utilization and application of concrete release agent at length.
Sorts of concrete release agent
Concrete release agents can be divided into several types according to different classification techniques, and the common grouping techniques are the subsequent:
- According to the opportunity of use: it can be divided into concrete release agent for building, concrete release agent for bridges, concrete emission agent for tunnels and and so forth.
- According to the the formula of: it can be divided into water-based concrete release agents, oil-based concrete release brokers, silicone oil concrete release agents, etc.
- According to the the use effect: it can be divided into ordinary concrete release brokers, simple to remove concrete release agents, high-gloss concrete release brokers 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 actually a sort of substance coated on the inner wall of the formwork to play the function of lubricating and remoteness to ensure that the concrete can be smoothly detached from the formwork when taking down the formwork, and the shape of the concrete can be kept intact and undamaged. Compared with the conventional release materials motor oil or waste motor oil, the release agent has the advantages of simple release, no pollution of the concrete covering, no corrosion of the template, effortless to paint, low value and etc. However, not all kinds of concrete release representatives with a variety of components made of templates are suitable for different components of the template and different development circumstances and finish requirements of the concrete must be selected for the ideal release agent in order to receive good results.
As an essential construction auxiliary material, concrete release agent has the subsequent qualities:
Good separation efficiency: concrete release agent can form a dense isolation movie between the formwork and the concrete surface, effectively stopping the formwork from bonding with the concrete covering and facilitating the removing.
Great lubrication performance: concrete release agent has good lubricating performance, which can reduce the friction between the formwork and concrete surface, reduce the resistance during pouring and improve the construction productivity.
Good anti-adhesion overall performance: concrete release agents can efficiently stop the formwork from bonding with the concrete surface, steering clear of the formwork from damaging the concrete area when dismantling the formwork.
Excellent waterproof overall performance: concrete release agent has good waterproof performance, which can successfully prevent 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 surface.
Demolding: Demolding can be carried out after the concrete reaches the strength of demolding. When taking down the formwork, the connectors at the edge of the formwork should be dismantled first, and then the area 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 dismantling.
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 development projects, mainly including the following aspects:
Reinforced concrete structure: In the construction of a reinforced concrete structure, concrete release representatives 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 surface 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 enhance 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 development projects. By choosing the right sort, 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.
