What exactly is a concrete release agent?
A concrete release agent is actually a compound applied to the building design just before the concrete is poured so that the template will not adhere to the concrete surface after pouring, isn’t effortless to take apart the form or impacts the complete of the concrete area. Its principal role in the template and the concrete surface to form a movie that will probably be separated from the two is additionally referred to as an isolation agent.
A water-based release agent is definitely an essential auxiliary within the release agent and can modify the water-based release agent stream and levelling; its principal characteristic 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 items functional processing ingredients; in the rubber, plastic, and Jinsu processing business, manufacturing cast goods are not only to be able to let the cast release to improve productivity and prolong the life of the form utilize. And can make the product thoroughly clean, size qualified, and decrease the creation of scrap, which is an crucial additional important to forms and goods – Water-based Concrete Release Agent.
Concrete release agent plays an important role in modern building construction; its main role is always to develop a layer of remoteness film between the design and the concrete area to ensure that the template doesn’t adhere to the concrete covering so that it is simpler to take apart the mould right after flowing and to maintain the end of the concrete covering. Here, we will present the kinds, characteristics, usage and use of concrete release agent in detail.
Kinds of concrete release agent
Concrete release representatives can be divided into many kinds according to different classification strategies, and the typical grouping strategies are the following:
- According to the scope of use: it can be divided into concrete release agent for development, concrete release agent for bridges, concrete launch agent for tunnels and so on.
- According to the the composition: it can be divided into water-based concrete release brokers, oil-based concrete release representatives, silicone oil concrete release brokers, etc.
- According to the effect of use: it can be divided into ordinary concrete release brokers, an easy task to remove concrete release brokers, high-gloss concrete release representatives and so on.
Characteristics of Concrete release agent
A concrete release agent is also called a concrete isolation 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 lubricating and remoteness so that the concrete may be easily detached from the formwork when taking down the formwork, and the shape of the concrete can be kept intact and undamaged. Compared with the standard release substance motor oil or waste motor oil, the release agent has the benefits of easy release, no pollution of the concrete surface, no corrosion of the template, simple to paint, low value and and so forth. However, not all types of concrete release representatives with a selection of components made of templates are suitable for different components of the template and different development conditions and finish requirements of the concrete must be selected for the suitable release agent in order to receive good results.
As an crucial construction auxiliary material, concrete release agent has the next features:
Good separation efficiency: concrete release agent can form a dense isolation movie between the formwork and the concrete area, efficiently stopping the formwork from bonding with the concrete surface and facilitating the dismantling.
Good lubrication performance: concrete release agent has good lubricating overall performance, which can lower the rubbing between the formwork and concrete covering, lower the resistance during pouring and boost the construction effectiveness.
Excellent anti-adhesion efficiency: concrete release brokers can effectively prevent the formwork from bonding with the concrete covering, steering clear of the formwork from damaging the concrete area when taking apart the formwork.
Excellent waterproof overall 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 enhancing the service life of the formwork.
Simple 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 dismantling 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 area gradually. In case of tight bonding between the formwork and the concrete area, 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, preventing 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 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 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 boost the construction efficiency and quality of the building project and provide a strong guarantee for the advancement of the construction industry.
