What is actually a concrete release agent?
A concrete release agent is definitely a substance applied to the construction design just before the concrete is added so that the design will not adhere to the concrete covering after pouring, is just not easy to take apart the cast or impacts the end of the concrete area. Its primary role in the template and the concrete covering to form a film that will probably be separated from the two can also be called an separation agent.
A water-based release agent is an essential auxiliary in the release agent and can modify the water-based release agent stream and levelling; its primary feature is actually stability to microorganisms and enzymes, which can reduce the cost of raw materials. A water-based form release agent can be used in forms and items functional processing ingredients; in the rubber, plastic, and Jinsu processing market, manufacturing form products are not only in order to let the form release to boost productivity and prolong the life of the form make use of. And can make the item clean, size qualified, and lower the technology of scrap, that is an essential additional vital to forms and goods – Water-based Concrete Release Agent.
Concrete release agent plays an important role in modern building construction; its primary role would be to create a layer of isolation film between the template and the concrete surface to ensure that the template doesn’t stick to to the concrete covering so that it is much easier to take apart the form following pouring and to maintain the complete of the concrete area. Here, we will introduce the kinds, qualities, utilization and use of concrete release agent at length.
Types of concrete release agent
Concrete release representatives can be divided into several sorts in accordance with different category methods, and the typical grouping techniques are the subsequent:
- According to the scope of use: it can be divided into concrete release agent for construction, concrete release agent for bridges, concrete discharge agent for tunnels and so on.
- According to the composition of: it can be divided into water-based concrete release brokers, oil-based concrete release brokers, silicone oil concrete release representatives, etc.
- According to the use effect: it can be divided into ordinary concrete release agents, simple to remove concrete release representatives, high-gloss concrete release representatives and so on.
Qualities of Concrete release agent
A concrete release agent is additionally referred to as a concrete separation agent or mould release lubricant. It is a kind of material coated on the inner wall of the formwork to play the function of lubrication and remoteness in order that the concrete could be effortlessly detached from the formwork when dismantling the formwork, and the shape of the concrete may 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 surface, no corrosion of the template, easy to paint, low price and etc. However, not all kinds of concrete release agents with a array of materials made of templates are suitable for different materials 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 crucial construction auxiliary material, concrete release agent has the subsequent features:
Good separation overall performance: concrete release agent can create a dense isolation motion picture between the formwork and the concrete area, successfully avoiding the formwork from bonding with the concrete covering and facilitating the demolding.
Excellent lubrication performance: concrete release agent has good lubrication efficiency, which can decrease the rubbing between the formwork and concrete surface, reduce the resistance during pouring and enhance the construction efficiency.
Great anti-adhesion efficiency: concrete release representatives can successfully prevent the formwork from bonding with the concrete surface, preventing the formwork from damaging the concrete surface when taking apart the formwork.
Good waterproof performance: concrete release agent has good waterproof overall performance, which can efficiently 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 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 dismantling 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 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 building projects, mainly including the following aspects:
Reinforced concrete structure: In the construction of a reinforced concrete structure, concrete release representatives can be used for formwork isolation, avoiding 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 surface and boost 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 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 important construction auxiliary material, plays an indispensable role in modern building 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 development of the development industry.
