What is actually a concrete release agent?
A concrete release agent is a compound applied to the construction design before the concrete is added in order that the template does not stick to the concrete area after pouring, is not easy to take down the mould or affects the complete of the concrete covering. Its principal role in the template and the concrete covering to create a motion picture that will probably be separated from the two is also known as an remoteness agent.
A water-based release agent is definitely an crucial supplementary inside the release agent and can change the water-based release agent circulation and levelling; its main characteristic is stability to microorganisms and enzymes, which can decrease the cost of raw materials. A water-based mould release agent is utilized in forms and products functional processing supplements; in the rubber, plastic, and Jinsu processing market, manufacturing form items aren’t just to be able to let the cast release to enhance productivity and lengthen the life of the form use. And can make the item thoroughly clean, size qualified, and reduce the generation of scrap, which is an crucial additive important to forms and items – concrete release agent.
Concrete release agent plays an essential role within modern building building; its primary role is to create a layer of isolation film between the design and the concrete surface to ensure that the template will not stick to the concrete area so that it is simpler to dismantle the mould after flowing and to maintain the finish of the concrete surface. Here, we will present the types, features, use and use of concrete release agent in more detail.
Sorts of concrete release agent
Concrete release brokers can be divided into numerous types based on 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 construction, concrete release agent for bridges, concrete emission agent for tunnels and etc.
- According to the formula of: it can be divided into water-based concrete release representatives, oil-based concrete release agents, silicone oil concrete release agents, etc.
- According to the effect of use: it can be divided into ordinary concrete release representatives, easy-to-remove concrete release brokers, high-gloss concrete release representatives and so on.
Features of Concrete release agent
A concrete release agent is additionally known as a concrete separation agent or mould release lubricant. It is actually a type of substance coated on the inner wall of the formwork to play the function of lubricating and remoteness in order that the concrete can be smoothly detached from the formwork when dismantling the formwork, and the form of the concrete could be kept intact and undamaged. Compared with the traditional release materials motor oil or waste motor oil, the release agent has the advantages of easy 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 agents with a selection of components made of templates are suitable for different supplies of the template and different building problems and finish requirements of the concrete must be selected for the appropriate release agent in order to receive good results.
As an essential construction auxiliary material, concrete release agent has the next qualities:
Good remoteness efficiency: concrete release agent can develop a dense remoteness motion picture between the formwork and the concrete surface, successfully preventing the formwork from bonding with the concrete surface and facilitating the dismantling.
Excellent lubrication overall performance: concrete release agent has good lubricating performance, which can lower the chaffing between the formwork and concrete covering, reduce the resistance during pouring and enhance the construction productivity.
Excellent anti-adhesion efficiency: concrete release agents can effectively stop the formwork from bonding with the concrete covering, steering clear of the formwork from damaging the concrete area when dismantling the formwork.
Excellent waterproof efficiency: concrete release agent has good waterproof performance, which can efficiently prevent moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and increasing 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 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 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 surface, 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 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, stopping formwork from bonding with concrete and improving 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 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 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 essential construction auxiliary material, plays an indispensable role in modern construction projects. By choosing the right sort, the correct use method and a reasonable application field, can effectively enhance the construction efficiency and quality of the development project and provide a strong guarantee for the development of the construction industry.
