What exactly is a concrete release agent?
A concrete release agent is a material put on the building template before the concrete is put so the template does not stick to to the concrete area after flowing, is not easy to take down the cast or impacts the complete of the concrete covering. Its principal role in the template and the concrete covering to form a film that will probably be separated from the two is also known as an isolation agent.
A water-based release agent is surely an essential ancillary within the release agent and can modify the water-based release agent stream and levelling; its principal attribute is stability to microorganisms and enzymes, which can decrease the expense of raw materials. A water-based cast release agent is utilized in forms and goods functional processing additives; in the rubber, plastic, and Jinsu processing market, manufacturing form items are not only to be able to let the form release to enhance productivity and lengthen the life of the mould use. And can make the merchandise clean, size qualified, and decrease the technology of scrap, that is an crucial additional essential to casts and products – Water-based Concrete Release Agent.
Concrete release agent plays an important role within modern building building; its principal role would be to develop a layer of isolation film between the design and the concrete covering so that the template does not stick to to the concrete area to ensure that it is much easier to take apart the form after putting and to maintain the finish of the concrete area. Here, we will introduce the sorts, characteristics, usage and use of concrete release agent in more detail.
Sorts of concrete release agent
Concrete release representatives can be divided into numerous sorts in accordance with different grouping techniques, and the common classification techniques are as follows:
- 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 and so forth.
- According to the formula of: it can be divided into water-based concrete release brokers, oil-based concrete release agents, silicone oil concrete release representatives, etc.
- According to the the utilization effect: it can be divided into ordinary concrete release representatives, easy-to-remove concrete release agents, high-gloss concrete release agents and and so forth.
Characteristics of Concrete release agent
A concrete release agent is also called a concrete isolation agent or mould release lubricant. It is a sort of substance coated on the inner wall of the formwork to play the function of lubrication and isolation in order that the concrete can be smoothly detached from the formwork when dismantling the formwork, and the form 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 positive aspects of effortless release, no pollution of the concrete covering, no corrosion of the template, simple to paint, low value and and so forth. However, not all types of concrete release representatives with a variety of components made of templates are suitable for different supplies of the template and different construction 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 next features:
Good remoteness overall performance: concrete release agent can create a dense isolation film between the formwork and the concrete covering, successfully stopping the formwork from bonding with the concrete area and facilitating the demolding.
Excellent lubrication efficiency: concrete release agent has good lubricating performance, which can lower the chaffing between the formwork and concrete surface, reduce the resistance during pouring and enhance the construction efficiency.
Great anti-adhesion overall performance: concrete release brokers can effectively avoid the formwork from bonding with the concrete covering, preventing the formwork from damaging the concrete covering when taking down the formwork.
Excellent waterproof efficiency: concrete release agent has good waterproof performance, 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.
Effortless 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 area.
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 surface, tools can be used appropriately to assist in the dismantling.
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 building projects, mainly including the following aspects:
Reinforced concrete structure: In the building 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 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 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 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 agents 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 boost the construction efficiency and quality of the development project and provide a strong guarantee for the development of the building industry.
