What is actually a concrete release agent?
A concrete release agent is actually a substance put on the construction design prior to the concrete is added in order that the design will not stick to the concrete area right after pouring, is just not easy to take apart the form or influences the complete of the concrete surface. Its principal role in the template and the concrete surface to form a motion picture that is going to be separated from the two can also be known as an remoteness agent.
A water-based release agent is surely an essential auxiliary within the release agent and can modify the water-based release agent circulation and levelling; its main attribute is definitely stability to microorganisms and enzymes, which can reduce the expense of raw materials. A water-based cast release agent can be used in casts and goods functional processing ingredients; in the rubber, plastic, and Jinsu processing market, manufacturing form goods aren’t just to be able to let the form release to improve productivity and extend the life of the form utilize. And can make the item clean, size qualified, and decrease the generation of scrap, that is an crucial additional essential to forms and products – concrete release agent.
Concrete release agent plays an essential role within modern building construction; its primary role is always to develop a layer of separation movie between the template and the concrete area so that the template does not stick to to the concrete covering to ensure that it is simpler to take down the mould right after putting and to maintain the complete of the concrete covering. Here, we will introduce the sorts, qualities, utilization and program of concrete release agent at length.
Kinds of concrete release agent
Concrete release agents can be divided into numerous types in accordance with different classification techniques, and the common grouping techniques are the subsequent:
- According to the the scope of use: it can be divided into concrete release agent for construction, concrete release agent for bridges, concrete emission agent for tunnels and and so forth.
- According to the the formula of: it can be divided into water-based concrete release brokers, oil-based concrete release representatives, silicone oil concrete release agents, etc.
- According to the use effect: it can be divided into ordinary concrete release representatives, easy-to-remove concrete release brokers, high-gloss concrete release brokers and etc.
Features of Concrete release agent
A concrete release agent can also be referred to as a concrete remoteness agent or mould release lubricant. It is a type of material coated on the inner wall of the formwork to play the role of lubricating and isolation so that the concrete could be smoothly detached from the formwork when dismantling the formwork, and the condition of the concrete could be kept intact and undamaged. Compared with the standard release material motor oil or waste motor oil, the release agent has the advantages of easy release, no pollution of the concrete area, no corrosion of the template, effortless to paint, low price and so on. However, not all types of concrete release brokers with a array of supplies made of templates are suitable for different supplies of the template and different development problems and finish requirements of the concrete must be selected for the ideal release agent in order to receive good results.
As an essential construction auxiliary material, concrete release agent has the next qualities:
Good isolation overall performance: concrete release agent can create a dense isolation motion picture between the formwork and the concrete surface, effectively stopping the formwork from bonding with the concrete surface and facilitating the dismantling.
Excellent lubrication efficiency: concrete release agent has good lubricating efficiency, which can reduce the chaffing between the formwork and concrete surface, lower the resistance during pouring and boost the construction effectiveness.
Excellent anti-adhesion overall performance: concrete release agents can successfully prevent the formwork from bonding with the concrete covering, steering clear of the formwork from damaging the concrete surface when taking down the formwork.
Excellent waterproof efficiency: concrete release agent has good waterproof overall performance, which can effectively avoid moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and improving the service life of the formwork.
Easy 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 surface.
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 covering of the formwork should be knocked gently to separate the formwork from the concrete covering gradually. In case of tight bonding between the formwork and the concrete surface, tools can be used appropriately to assist in the taking apart.
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 brokers 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 area, 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 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 brokers 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 enhance the construction efficiency and quality of the development project and provide a strong guarantee for the growth of the construction industry.
