What is actually a concrete release agent?
A concrete release agent is a substance placed on the construction template just before the concrete is put in order that the template will not adhere to the concrete covering right after putting, is just not simple to dismantle the mould or impacts the end of the concrete surface. Its main role within the design and the concrete surface to develop a film that is going to be separated from the two is also called an remoteness agent.
A water-based release agent is definitely an crucial auxiliary inside the release agent and can modify the water-based release agent stream and levelling; its main feature is stability to microorganisms and enzymes, which can decrease the cost of raw materials. A water-based form release agent is utilized in moulds and goods functional processing supplements; in the rubber, plastic, and Jinsu processing business, manufacturing form items aren’t just in order to let the cast release to enhance productivity and lengthen the life of the cast utilize. And can make the merchandise clean, size qualified, and lower the generation of scrap, which is an important additional important to moulds and products – concrete release agent.
Concrete release agent plays an crucial role within modern building construction; its principal role is to create a layer of remoteness film between the design and the concrete area so that the template does not stick to to the concrete surface so that it is simpler to take down the cast after pouring and to maintain the end of the concrete area. Here, we will present the kinds, characteristics, use and program of concrete release agent in more detail.
Kinds of concrete release agent
Concrete release agents can be divided into many sorts according to different category methods, and the common category techniques are the subsequent:
- According to the the opportunity of use: it can be divided into concrete release agent for development, concrete release agent for bridges, concrete discharge agent for tunnels and and so forth.
- According to the formula of: it can be divided into water-based concrete release agents, petroleum-based concrete release agents, silicone oil concrete release brokers, etc.
- According to the effect of use: it can be divided into ordinary concrete release brokers, simple to remove concrete release brokers, high-gloss concrete release representatives and etc.
Characteristics of Concrete release agent
A concrete release agent can also be referred to as a concrete separation agent or mould release lubricant. It is really a kind of substance coated on the inner wall of the formwork to play the role of lubrication and separation to ensure that the concrete may be effortlessly detached from the formwork when dismantling the formwork, and the shape of the concrete can be kept intact and undamaged. Compared with the traditional release substance motor oil or waste motor oil, the release agent has the positive aspects of simple release, no pollution of the concrete surface, no corrosion of the template, simple to paint, low price and so on. However, not all types 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 crucial construction auxiliary material, concrete release agent has the subsequent qualities:
Good remoteness efficiency: concrete release agent can develop a dense remoteness movie between the formwork and the concrete surface, successfully avoiding the formwork from bonding with the concrete covering and facilitating the dismantling.
Good lubrication overall performance: concrete release agent has good lubrication performance, which can decrease the chaffing between the formwork and concrete covering, decrease the resistance during pouring and enhance the construction productivity.
Great anti-adhesion performance: concrete release agents can successfully stop the formwork from bonding with the concrete surface, preventing the formwork from damaging the concrete surface when taking apart the formwork.
Great waterproof performance: concrete release agent has good waterproof performance, which can successfully avoid moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and enhancing the service life of the formwork.
Effortless to use and safe: concrete release agent is effortless 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 covering.
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 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 surface, tools can be used appropriately to assist in the taking apart.
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 building 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 increasing 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 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 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 building projects.
In conclusion, concrete release agent, as an crucial construction auxiliary material, plays an indispensable role in modern building 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 construction project and provide a strong guarantee for the development of the construction industry.
