What is actually a concrete release agent?
A concrete release agent is a material applied to the building template prior to the concrete is put so that the template doesn’t adhere to the concrete area right after pouring, isn’t effortless to take down the cast or influences the finish of the concrete covering. Its principal role inside the template and the concrete covering to create a film that is going to be separated from the two is also known as an remoteness agent.
A water-based release agent is an essential ancillary inside the release agent and can change the water-based release agent circulation and levelling; its principal characteristic is stability to microorganisms and enzymes, which can lower the expense of raw materials. A water-based form release agent is used in casts and items functional processing supplements; in the rubber, plastic, and Jinsu processing business, manufacturing cast items aren’t just to be able to let the form release to enhance productivity and prolong the life of the mould make use of. And can make the merchandise thoroughly clean, size qualified, and decrease the creation of scrap, that is an crucial additive important to moulds and goods – concrete additive.
Concrete release agent plays an essential role inside modern building building; its principal role is always to create a layer of remoteness motion picture between the design and the concrete area so that the template doesn’t adhere to the concrete area to ensure that it is simpler to dismantle the mould following putting and to maintain the finish of the concrete area. Here, we will unveil the types, features, usage and use of concrete release agent in detail.
Sorts of concrete release agent
Concrete release representatives can be divided into many kinds according to different classification strategies, and the common category methods are the following:
- According to the the scope of use: it can be divided into concrete release agent for development, concrete release agent for bridges, concrete emission 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 representatives, silicone oil concrete release brokers, etc.
- According to the the effect of use: it can be divided into ordinary concrete release agents, simple to remove concrete release representatives, high-gloss concrete release brokers and etc.
Qualities of Concrete release agent
A concrete release agent is additionally called a concrete separation agent or mould release lubricant. It is actually a kind of compound coated on the inner wall of the formwork to play the part of lubricating and remoteness to ensure that the concrete can be smoothly detached from the formwork when taking down the formwork, and the condition of the concrete can be kept intact and undamaged. Compared with the standard release material motor oil or waste motor oil, the release agent has the benefits of effortless release, no pollution of the concrete area, no corrosion of the template, simple to paint, low value and and so forth. However, not all kinds of concrete release agents with a variety of materials made of templates are suitable for different components of the template and different development problems 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 following characteristics:
Good isolation overall performance: concrete release agent can develop a dense separation motion picture between the formwork and the concrete covering, efficiently preventing the formwork from bonding with the concrete covering and facilitating the demolding.
Good lubrication performance: concrete release agent has good lubrication performance, which can lower the friction between the formwork and concrete covering, decrease the resistance during pouring and improve the construction productivity.
Excellent anti-adhesion efficiency: concrete release brokers can effectively avoid the formwork from bonding with the concrete covering, avoiding the formwork from damaging the concrete area when taking down the formwork.
Excellent waterproof performance: 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 improving 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 surface 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 area, 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 development 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 covering, 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 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 crucial construction auxiliary material, plays an indispensable role in modern development projects. By choosing the right type, the correct use method and a reasonable application field, can effectively improve the construction efficiency and quality of the building project and provide a strong guarantee for the growth of the development industry.
