What is actually a concrete release agent?
A concrete release agent is definitely a substance put on the building design just before the concrete is added in order that the design will not stick to to the concrete surface following pouring, is just not easy to take apart the form or impacts the end of the concrete area. Its principal role within the design and the concrete surface to create a motion picture that will be separated from the two is also called an remoteness agent.
A water-based release agent is definitely an essential auxiliary inside the release agent and can change the water-based release agent circulation and levelling; its main attribute is stability to microorganisms and enzymes, which can reduce the cost of raw materials. A water-based form release agent is utilized in moulds and products functional processing ingredients; in the rubber, plastic, and Jinsu processing business, manufacturing form items are not only in order to let the mould release to improve productivity and prolong the life of the form utilize. And can make the item clean, size qualified, and decrease the generation of scrap, which is an essential supplementary important to casts and products – concrete additive.
Concrete release agent plays an crucial role within modern building construction; its principal role would be to form a layer of remoteness movie between the design and the concrete surface to ensure that the design doesn’t stick to the concrete surface to ensure that it is easier to take apart the mould after flowing and to maintain the finish of the concrete area. Here, we will unveil the sorts, qualities, use and program of concrete release agent at length.
Kinds of concrete release agent
Concrete release brokers can be divided into numerous types based on different classification techniques, and the frequent category techniques are the subsequent:
- According to the scope of use: it can be divided into concrete release agent for building, concrete release agent for bridges, concrete discharge agent for tunnels and and so forth.
- According to the the composition of: it can be divided into water-based concrete release agents, oil-based concrete release agents, silicone oil concrete release representatives, etc.
- According to the the use effect: it can be divided into ordinary concrete release agents, easy-to-remove concrete release brokers, high-gloss concrete release brokers and so on.
Features of Concrete release agent
A concrete release agent is additionally called a concrete isolation agent or mould release lubricant. It is actually a kind of compound coated on the inner wall of the formwork to play the function of lubrication and isolation so that the concrete can be smoothly detached from the formwork when taking apart the formwork, and the form of the concrete may 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 cost and so on. However, not all sorts of concrete release representatives with a array of materials made of templates are suitable for different materials of the template and different development circumstances and finish requirements of the concrete must be selected for the suitable release agent in order to receive good results.
As an essential construction auxiliary material, concrete release agent has the subsequent features:
Good separation performance: concrete release agent can create a dense isolation movie between the formwork and the concrete surface, efficiently stopping the formwork from bonding with the concrete surface and facilitating the dismantling.
Great lubrication efficiency: concrete release agent has good lubrication performance, which can reduce the friction between the formwork and concrete area, decrease the resistance during pouring and improve the construction efficiency.
Great anti-adhesion efficiency: concrete release representatives can successfully stop the formwork from bonding with the concrete covering, steering clear of the formwork from damaging the concrete covering when dismantling the formwork.
Excellent waterproof efficiency: concrete release agent has good waterproof overall performance, which can successfully prevent moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and increasing the service life of the formwork.
Simple 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 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 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 area of the formwork should be knocked gently to separate the formwork from the concrete covering gradually. In case of tight bonding between the formwork and the concrete covering, tools can be used appropriately to assist in the taking apart.
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 development 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 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 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 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 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 important 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 improve the construction efficiency and quality of the development project and provide a strong guarantee for the growth of the development industry.
