What is a concrete release agent?
A concrete release agent is actually a material put on the construction template prior to the concrete is poured so the template will not adhere to the concrete area following putting, is not effortless to dismantle the mould or influences the end of the concrete covering. Its principal role in the template and the concrete area to develop a film that will be separated from the two is also referred to as an isolation agent.
A water-based release agent is definitely an crucial ancillary in the release agent and can modify the water-based release agent circulation and levelling; its primary characteristic is stability to microorganisms and enzymes, which can decrease the cost of raw materials. A water-based mould release agent can be used in casts and products functional processing additives; in the rubber, plastic, and Jinsu processing business, manufacturing cast products aren’t just to be able to let the form release to enhance productivity and extend the life of the cast make use of. And can make the product clean, size qualified, and reduce the technology of scrap, which is an crucial additive vital to forms and goods – concrete additive.
Concrete release agent plays an crucial role within modern building development; its main role would be to form a layer of separation movie between the design and the concrete covering so that the design does not adhere to the concrete surface in order that it is simpler to dismantle the cast after flowing and to maintain the end of the concrete covering. Here, we will present the kinds, qualities, usage and application of concrete release agent in more detail.
Kinds of concrete release agent
Concrete release representatives can be divided into numerous kinds in accordance with different grouping methods, and the frequent classification strategies are the subsequent:
- According to the opportunity of use: it can be divided into concrete release agent for construction, concrete release agent for bridges, concrete discharge agent for tunnels and etc.
- According to the formula of: it can be divided into water-based concrete release agents, oil-based concrete release representatives, silicone oil concrete release representatives, etc.
- According to the effect of use: it can be divided into ordinary concrete release brokers, simple to remove concrete release representatives, high-gloss concrete release representatives and so on.
Qualities of Concrete release agent
A concrete release agent is additionally referred to as a concrete remoteness agent or mould release lubricant. It is a type of substance coated on the inner wall of the formwork to play the role of lubrication and remoteness so that the concrete could be effortlessly detached from the formwork when taking down the formwork, and the form of the concrete can 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 surface, no corrosion of the template, effortless to paint, low price and etc. However, not all sorts of concrete release representatives with a variety of components made of templates are suitable for different materials of the template and different development circumstances and finish requirements of the concrete must be selected for the ideal release agent in order to receive good results.
As an important construction auxiliary material, concrete release agent has the subsequent qualities:
Good remoteness overall performance: concrete release agent can develop a dense remoteness film between the formwork and the concrete area, effectively avoiding the formwork from bonding with the concrete surface and facilitating the demolding.
Good lubrication efficiency: concrete release agent has good lubrication performance, which can reduce the friction between the formwork and concrete covering, lower the resistance during pouring and improve the construction efficiency.
Good anti-adhesion performance: concrete release representatives can effectively avoid the formwork from bonding with the concrete surface, preventing the formwork from damaging the concrete covering when taking down the formwork.
Good waterproof efficiency: concrete release agent has good waterproof efficiency, which can efficiently prevent moisture from penetrating between the formwork and concrete, steering clear of 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 surface.
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 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 surface, tools can be used appropriately to assist in the dismantling.
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 brokers 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 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 boost 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 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 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 type, the correct use method and a reasonable application field, can effectively enhance the construction efficiency and quality of the construction project and provide a strong guarantee for the advancement of the building industry.
