What is actually a concrete release agent?
A concrete release agent is actually a compound applied to the construction template just before the concrete is poured in order that the design does not stick to the concrete surface right after pouring, is just not effortless to take down the mould or impacts the complete of the concrete area. Its principal role in the template and the concrete area to create a movie that will be separated from the two is additionally called an isolation agent.
A water-based release agent is surely an important ancillary within the release agent and can change the water-based release agent flow and levelling; its principal attribute is actually stability to microorganisms and enzymes, which can decrease the cost of raw materials. A water-based cast release agent can be used in moulds and goods functional processing ingredients; in the rubber, plastic, and Jinsu processing business, manufacturing form goods are not only in order to let the cast release to boost productivity and extend the life of the mould utilize. And can make the merchandise clean, size qualified, and lower the technology of scrap, which can be an crucial supplementary vital to casts and goods – concrete additive.
Concrete release agent plays an important role in modern building development; its primary role would be to create a layer of remoteness motion picture between the template and the concrete surface so that the template will not stick to the concrete covering to ensure that it is much easier to take down the cast following putting and to maintain the end of the concrete area. Here, we will introduce the types, qualities, utilization and use of concrete release agent in more detail.
Types of concrete release agent
Concrete release agents can be divided into several kinds based on different grouping methods, and the frequent category 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 formula of: it can be divided into water-based concrete release representatives, petroleum-based concrete release representatives, silicone oil concrete release representatives, etc.
- According to the effect of use: it can be divided into ordinary concrete release agents, simple to remove concrete release brokers, high-gloss concrete release agents and so on.
Features of Concrete release agent
A concrete release agent can also be called a concrete remoteness agent or mould release lubricant. It is really a type of material coated on the inner wall of the formwork to play the part of lubricating and separation to ensure that the concrete may be easily detached from the formwork when taking apart the formwork, and the condition of the concrete may be kept intact and undamaged. Compared with the traditional release materials 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 agents with a array of materials made of templates are suitable for different materials of the template and different construction circumstances and finish requirements of the concrete must be selected for the suitable release agent in order to receive good results.
As an essential construction auxiliary material, concrete release agent has the next characteristics:
Good remoteness performance: concrete release agent can form a dense isolation movie between the formwork and the concrete area, effectively stopping the formwork from bonding with the concrete covering and facilitating the removing.
Great lubrication efficiency: concrete release agent has good lubrication efficiency, which can lower the rubbing between the formwork and concrete surface, decrease the resistance during pouring and improve the construction effectiveness.
Good anti-adhesion performance: concrete release brokers can efficiently prevent the formwork from bonding with the concrete covering, avoiding the formwork from damaging the concrete surface when dismantling the formwork.
Excellent waterproof efficiency: concrete release agent has good waterproof overall performance, which can efficiently stop moisture from penetrating between the formwork and concrete, avoiding deformation of the formwork by moisture and enhancing 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 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 area 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 development projects, mainly including the following aspects:
Reinforced concrete structure: In the construction of a reinforced concrete structure, concrete release agents 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 covering 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 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 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 sort, 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 development of the development industry.
