What is a concrete release agent?
A concrete release agent is a compound placed on the building template prior to the concrete is poured in order that the template doesn’t adhere to the concrete covering after pouring, isn’t easy to take apart the form or influences the complete of the concrete surface. Its main role within the template and the concrete covering to develop a film that will probably be separated from the two can also be referred to as an separation agent.
A water-based release agent is surely an crucial auxiliary within the release agent and can modify the water-based release agent circulation and levelling; its principal attribute is actually stability to microorganisms and enzymes, which can reduce the cost of raw materials. A water-based cast release agent can be used in forms and products functional processing supplements; in the rubber, plastic, and Jinsu processing industry, manufacturing cast goods are not just so as to let the cast release to boost productivity and extend the life of the form utilize. And can make the item thoroughly clean, size qualified, and reduce the creation of scrap, which can be an essential additional vital to casts and products – concrete release agent.
Concrete release agent plays an important role within modern building construction; its primary role is always to develop a layer of remoteness film between the template and the concrete covering to ensure that the template does not stick to to the concrete surface to ensure that it is simpler to dismantle the form right after pouring and to maintain the end of the concrete surface. Here, we will unveil the types, qualities, usage and use of concrete release agent in more detail.
Sorts of concrete release agent
Concrete release agents can be divided into numerous types according to different classification methods, and the frequent classification techniques are the following:
- 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 etc.
- According to the composition: it can be divided into water-based concrete release representatives, oil-based concrete release brokers, silicone oil concrete release brokers, etc.
- According to the the utilization effect: it can be divided into ordinary concrete release brokers, simple 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 known as a concrete separation agent or mould release lubricant. It is really a sort of material coated on the inner wall of the formwork to play the part of lubrication and isolation so that the concrete can 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 material motor oil or waste motor oil, the release agent has the advantages of effortless release, no pollution of the concrete area, no corrosion of the template, easy to paint, low cost and and so forth. However, not all kinds of concrete release brokers with a variety of components made of templates are suitable for different materials of the template and different building conditions and finish requirements of the concrete must be selected for the appropriate release agent in order to receive good results.
As an crucial construction auxiliary material, concrete release agent has the following characteristics:
Good isolation performance: concrete release agent can create a dense isolation movie between the formwork and the concrete surface, successfully stopping the formwork from bonding with the concrete area and facilitating the dismantling.
Great lubrication efficiency: concrete release agent has good lubrication performance, which can decrease the rubbing between the formwork and concrete surface, decrease the resistance during pouring and enhance the construction effectiveness.
Good anti-adhesion efficiency: concrete release agents can effectively avoid the formwork from bonding with the concrete surface, avoiding the formwork from damaging the concrete covering when taking apart the formwork.
Good waterproof efficiency: concrete release agent has good waterproof efficiency, which can successfully avoid moisture from penetrating between the formwork and concrete, steering clear of deformation of the formwork by moisture and improving 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 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 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 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 construction projects, mainly including the following aspects:
Reinforced concrete structure: In the construction of a reinforced concrete structure, concrete release brokers can be used for formwork isolation, stopping formwork from bonding with concrete and enhancing 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 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 essential 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 construction project and provide a strong guarantee for the growth of the development industry.
