What exactly is a concrete release agent?
A concrete release agent is actually a compound placed on the building design prior to the concrete is put in order that the template doesn’t stick to to the concrete covering right after pouring, is not easy to take apart the mould or impacts the end of the concrete covering. Its principal role within the template and the concrete surface to form a movie that will probably be separated from the two is also referred to as an isolation agent.
A water-based release agent is an important ancillary inside the release agent and can alter the water-based release agent stream and levelling; its main attribute is definitely stability to microorganisms and enzymes, which can lower the price of raw materials. A water-based form release agent can be used in casts and goods functional processing ingredients; in the rubber, plastic, and Jinsu processing business, manufacturing cast products are not only so as to let the cast release to enhance productivity and prolong the life of the mould make use of. And can make the product thoroughly clean, size qualified, and reduce the generation of scrap, which can be an crucial additional essential to forms and products – concrete release agent.
Concrete release agent plays an crucial role within modern building development; its primary role is always to create a layer of remoteness film between the template and the concrete covering in order that the template doesn’t stick to to the concrete area to ensure that it is simpler to take apart the mould following pouring and to maintain the complete of the concrete area. Here, we will present the kinds, features, usage and application of concrete release agent at length.
Sorts of concrete release agent
Concrete release brokers can be divided into many kinds in accordance with different classification techniques, and the typical category 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 discharge agent for tunnels and and so forth.
- According to the the composition: it can be divided into water-based concrete release agents, oil-based concrete release agents, silicone oil concrete release brokers, etc.
- According to the utilization effect: it can be divided into ordinary concrete release agents, simple to remove concrete release agents, high-gloss concrete release representatives and so on.
Characteristics of Concrete release agent
A concrete release agent is additionally referred to as a concrete remoteness agent or mould release lubricant. It is actually a sort of material coated on the inner wall of the formwork to play the role of lubricating and isolation in order that the concrete can be easily detached from the formwork when taking down the formwork, and the condition of the concrete may be kept intact and undamaged. Compared with the standard release materials motor oil or waste motor oil, the release agent has the advantages of easy release, no pollution of the concrete covering, no corrosion of the template, easy to paint, low value and etc. However, not all sorts of concrete release agents with a selection of materials made of templates are suitable for different materials of the template and different construction conditions 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 following characteristics:
Good isolation overall performance: concrete release agent can develop a dense separation motion picture between the formwork and the concrete covering, effectively preventing the formwork from bonding with the concrete surface and facilitating the removing.
Good lubrication overall performance: concrete release agent has good lubricating overall performance, which can reduce the friction between the formwork and concrete covering, lower the resistance during pouring and boost the construction effectiveness.
Good anti-adhesion efficiency: concrete release representatives can efficiently prevent the formwork from bonding with the concrete covering, avoiding the formwork from damaging the concrete surface when dismantling the formwork.
Good waterproof overall performance: concrete release agent has good waterproof performance, which can successfully stop moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and enhancing the service life of the formwork.
Effortless 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 surface.
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 area, 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 development projects, mainly including the following aspects:
Reinforced concrete structure: In the development of a reinforced concrete structure, concrete release agents can be used for formwork isolation, preventing 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 area 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 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 building projects.
In conclusion, concrete release agent, as an essential construction auxiliary material, plays an indispensable role in modern construction 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 growth of the development industry.
