What is a concrete release agent?
A concrete release agent is definitely a substance applied to the construction template before the concrete is poured in order that the template doesn’t stick to to the concrete surface after flowing, isn’t simple to take down the form or influences the end of the concrete area. Its primary role within the template and the concrete area to form a motion picture that is going to be separated from the two can also be referred to as an isolation agent.
A water-based release agent is definitely an essential auxiliary inside the release agent and can alter the water-based release agent circulation and levelling; its primary feature is stability to microorganisms and enzymes, which can lower the expense of raw materials. A water-based cast release agent is used in casts and products functional processing supplements; in the rubber, plastic, and Jinsu processing industry, manufacturing cast goods aren’t just in order to let the form release to improve productivity and extend the life of the mould make use of. And can make the item clean, size qualified, and decrease the technology of scrap, that is an essential additional vital to moulds and items – Water-based Concrete Release Agent.
Concrete release agent plays an important role in modern building building; its primary role is always to create a layer of isolation movie between the template and the concrete surface to ensure that the design doesn’t adhere to the concrete surface so that it is much easier to take down the form after pouring and to maintain the end of the concrete covering. Here, we will introduce the kinds, characteristics, use and use of concrete release agent in detail.
Types of concrete release agent
Concrete release brokers can be divided into many sorts in accordance with different classification techniques, and the common classification strategies are as follows:
- According to the the opportunity of use: it can be divided into concrete release agent for building, concrete release agent for bridges, concrete emission agent for tunnels and and so forth.
- According to the formula of: it can be divided into water-based concrete release brokers, petroleum-based concrete release representatives, silicone oil concrete release brokers, etc.
- According to the the use effect: it can be divided into ordinary concrete release brokers, an easy task to remove concrete release brokers, high-gloss concrete release representatives and etc.
Characteristics of Concrete release agent
A concrete release agent can also be known as a concrete remoteness agent or mould release lubricant. It is really a sort of compound coated on the inner wall of the formwork to play the role of lubrication and remoteness so that the concrete could be easily detached from the formwork when dismantling the formwork, and the form of the concrete can be kept intact and undamaged. Compared with the standard release materials motor oil or waste motor oil, the release agent has the benefits of easy release, no pollution of the concrete covering, no corrosion of the template, easy to paint, low price and and so forth. However, not all kinds of concrete release representatives with a variety of materials made of templates are suitable for different supplies of the template and different building circumstances and finish requirements of the concrete must be selected for the appropriate release agent in order to receive good results.
As an important construction auxiliary material, concrete release agent has the following qualities:
Good remoteness overall performance: concrete release agent can develop a dense isolation motion picture between the formwork and the concrete covering, efficiently preventing the formwork from bonding with the concrete area and facilitating the dismantling.
Excellent lubrication overall performance: concrete release agent has good lubrication efficiency, which can reduce the rubbing between the formwork and concrete surface, reduce the resistance during pouring and boost the construction effectiveness.
Good anti-adhesion overall performance: concrete release brokers can successfully avoid the formwork from bonding with the concrete area, avoiding the formwork from damaging the concrete area when taking apart the formwork.
Great waterproof overall performance: concrete release agent has good waterproof overall performance, which can effectively stop moisture from penetrating between the formwork and concrete, steering clear of deformation of the formwork by moisture and enhancing 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 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 surface 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 building projects, mainly including the following aspects:
Reinforced concrete structure: In the building of a reinforced concrete structure, concrete release representatives 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 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 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 enhance 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 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 improve the construction efficiency and quality of the development project and provide a strong guarantee for the advancement of the development industry.
