What is a concrete release agent?
A concrete release agent is actually a material put on the building template prior to the concrete is poured so the template does not adhere to the concrete surface following pouring, isn’t easy to dismantle the form or impacts the end of the concrete surface. Its main role in the design and the concrete surface to create a motion picture that is going to be separated from the two is also known as an separation agent.
A water-based release agent is surely an crucial auxiliary in the release agent and can alter the water-based release agent flow and levelling; its primary attribute is stability to microorganisms and enzymes, which can lower the price of raw materials. A water-based form release agent is utilized in casts and products functional processing additives; in the rubber, plastic, and Jinsu processing industry, manufacturing form items are not just in order to let the mould release to boost productivity and lengthen the life of the form use. And can make the product clean, size qualified, and reduce the creation of scrap, which can be an important additive important to casts and items – Water-based Concrete Release Agent.
Concrete release agent plays an important role within modern building building; its main role is always to form a layer of remoteness motion picture between the template and the concrete surface in order that the design will not stick to to the concrete covering in order that it is simpler to take down the cast following putting and to maintain the finish of the concrete surface. Here, we will unveil the sorts, characteristics, use and use of concrete release agent in detail.
Types of concrete release agent
Concrete release agents can be divided into numerous sorts according to different grouping strategies, and the frequent category strategies are as follows:
- According to the scope of use: it can be divided into concrete release agent for construction, concrete release agent for bridges, concrete launch agent for tunnels and so on.
- According to the formula of: it can be divided into water-based concrete release brokers, 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 brokers, easy-to-remove concrete release agents, high-gloss concrete release representatives and so on.
Qualities of Concrete release agent
A concrete release agent can also be called a concrete separation agent or mould release lubricant. It is actually a sort of material coated on the inner wall of the formwork to play the part of lubrication and remoteness so that the concrete may be easily detached from the formwork when taking down the formwork, and the form of the concrete may be kept intact and undamaged. Compared with the conventional release substance motor oil or waste motor oil, the release agent has the positive aspects of easy release, no pollution of the concrete covering, no corrosion of the template, simple to paint, low price and and so forth. However, not all sorts of concrete release brokers with a variety of supplies made of templates are suitable for different materials of the template and different building circumstances and finish requirements of the concrete must be selected for the ideal release agent in order to receive good results.
As an essential construction auxiliary material, concrete release agent has the subsequent features:
Good remoteness performance: concrete release agent can create a dense isolation film between the formwork and the concrete area, successfully stopping the formwork from bonding with the concrete surface and facilitating the dismantling.
Great lubrication performance: concrete release agent has good lubricating performance, which can lower the friction between the formwork and concrete covering, reduce the resistance during pouring and enhance the construction productivity.
Excellent anti-adhesion efficiency: concrete release brokers can successfully prevent the formwork from bonding with the concrete covering, preventing the formwork from damaging the concrete surface when dismantling the formwork.
Excellent waterproof efficiency: concrete release agent has good waterproof overall performance, which can successfully stop moisture from penetrating between the formwork and concrete, avoiding 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 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 covering 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 down.
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, preventing 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 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 area 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 important construction auxiliary material, plays an indispensable role in modern construction projects. By choosing the right kind, 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.
