What is actually a concrete release agent?
A concrete release agent is a compound placed on the development template just before the concrete is added in order that the template does not stick to the concrete covering following putting, is just not simple to take apart the form or influences the complete of the concrete covering. Its main role within the template and the concrete covering to create a film that will be separated from the two can also be called an separation agent.
A water-based release agent is an crucial ancillary within the release agent and can change the water-based release agent circulation and levelling; its main feature is stability to microorganisms and enzymes, which can lower the price of raw materials. A water-based cast release agent is utilized in casts and products functional processing ingredients; in the rubber, plastic, and Jinsu processing industry, manufacturing form products are not only so as to let the cast release to improve productivity and extend the life of the form use. And can make the merchandise clean, size qualified, and lower the creation of scrap, which is an crucial supplementary essential to casts and goods – concrete additive.
Concrete release agent plays an essential role in modern building development; its main role would be to develop a layer of remoteness film between the design and the concrete surface so that the template will not adhere to the concrete covering in order that it is simpler to take apart the form after flowing and to maintain the finish of the concrete covering. Here, we will present the sorts, features, use and program of concrete release agent in more detail.
Types of concrete release agent
Concrete release brokers can be divided into many sorts in accordance with different grouping strategies, and the typical classification strategies are as follows:
- According to the 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 so on.
- According to the composition of: it can be divided into water-based concrete release agents, oil-based concrete release representatives, silicone oil concrete release representatives, etc.
- According to the the utilization effect: it can be divided into ordinary concrete release representatives, an easy task to remove concrete release representatives, high-gloss concrete release brokers and and so forth.
Features of Concrete release agent
A concrete release agent can also be called a concrete separation agent or mould release lubricant. It is a type of compound coated on the inner wall of the formwork to play the part of lubricating and isolation in order that the concrete could be smoothly detached from the formwork when dismantling the formwork, and the shape of the concrete could be kept intact and undamaged. Compared with the standard release substance motor oil or waste motor oil, the release agent has the advantages of effortless release, no pollution of the concrete covering, no corrosion of the template, effortless to paint, low price and and so forth. However, not all sorts of concrete release agents with a array of supplies made of templates are suitable for different components of the template and different development circumstances 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 next characteristics:
Good separation overall performance: concrete release agent can create a dense isolation movie between the formwork and the concrete surface, efficiently preventing the formwork from bonding with the concrete covering and facilitating the dismantling.
Excellent lubrication efficiency: concrete release agent has good lubrication performance, which can lower the friction between the formwork and concrete surface, decrease the resistance during pouring and improve the construction productivity.
Great anti-adhesion efficiency: concrete release agents can successfully avoid the formwork from bonding with the concrete covering, steering clear of the formwork from damaging the concrete area when taking apart the formwork.
Good waterproof efficiency: concrete release agent has good waterproof performance, which can effectively 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 simple 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 taking apart 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 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 construction of a reinforced concrete structure, concrete release representatives 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 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 development 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 construction project and provide a strong guarantee for the advancement of the building industry.
