What is actually a concrete release agent?
A concrete release agent is a compound put on the building template just before the concrete is poured in order that the template will not stick to to the concrete covering following putting, is not effortless to take apart the mould or affects the end of the concrete area. Its main role inside the template and the concrete surface to create a film that will probably be separated from the two can also be called an remoteness agent.
A water-based release agent is definitely an important ancillary in the release agent and can change the water-based release agent circulation and levelling; its principal feature is definitely stability to microorganisms and enzymes, which can decrease the expense of raw materials. A water-based form release agent is utilized in moulds and products functional processing ingredients; in the rubber, plastic, and Jinsu processing market, manufacturing form goods are not just to be able to let the cast release to boost productivity and lengthen the life of the mould make use of. And can make the product thoroughly clean, size qualified, and decrease the creation of scrap, which can be an crucial additive essential to casts and products – Water-based Concrete Release Agent.
Concrete release agent plays an crucial role inside modern building building; its primary role is to form a layer of separation film between the design and the concrete area to ensure that the template doesn’t adhere to the concrete area to ensure that it is simpler to take down the mould right after putting and to maintain the complete of the concrete area. Here, we will unveil the kinds, characteristics, use and application of concrete release agent in detail.
Sorts of concrete release agent
Concrete release agents can be divided into many sorts according to different category techniques, and the typical grouping methods are the subsequent:
- According to the the scope of use: it can be divided into concrete release agent for building, concrete release agent for bridges, concrete emission agent for tunnels and and so forth.
- According to the composition of: it can be divided into water-based concrete release representatives, oil-based concrete release representatives, silicone oil concrete release representatives, etc.
- According to the utilization effect: it can be divided into ordinary concrete release brokers, simple to remove concrete release brokers, high-gloss concrete release brokers and and so forth.
Qualities of Concrete release agent
A concrete release agent can also be referred to as a concrete separation agent or mould release lubricant. It is really a kind of substance coated on the inner wall of the formwork to play the part of lubricating and isolation to ensure that the concrete may be smoothly detached from the formwork when taking down the formwork, and the condition of the concrete can be kept intact and undamaged. Compared with the conventional release materials motor oil or waste motor oil, the release agent has the benefits of effortless release, no pollution of the concrete area, no corrosion of the template, simple to paint, low value and etc. However, not all types of concrete release representatives with a array of supplies 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 ideal release agent in order to receive good results.
As an essential construction auxiliary material, concrete release agent has the subsequent characteristics:
Good separation overall performance: concrete release agent can create a dense separation film between the formwork and the concrete area, effectively stopping the formwork from bonding with the concrete surface and facilitating the demolding.
Good lubrication efficiency: concrete release agent has good lubricating performance, which can lower the rubbing between the formwork and concrete covering, decrease the resistance during pouring and enhance the construction effectiveness.
Great anti-adhesion overall performance: concrete release agents can successfully prevent the formwork from bonding with the concrete surface, preventing the formwork from damaging the concrete area when dismantling the formwork.
Excellent waterproof overall performance: concrete release agent has good waterproof performance, which can effectively prevent 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 simple 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 taking down.
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 construction of a reinforced concrete structure, concrete release brokers can be used for formwork isolation, stopping formwork from bonding with concrete and increasing 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 boost 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 development projects.
In conclusion, concrete release agent, as an essential construction auxiliary material, plays an indispensable role in modern development 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 construction project and provide a strong guarantee for the development of the construction industry.
