What exactly is a concrete release agent?
A concrete release agent is actually a compound put on the building template just before the concrete is added in order that the design does not adhere to the concrete covering right after flowing, is just not effortless to take apart the form or influences the end of the concrete surface. Its principal role inside the design and the concrete area to form a motion picture that will probably be separated from the two can also be referred to as an remoteness agent.
A water-based release agent is an important supplementary within the release agent and can alter the water-based release agent circulation and levelling; its main attribute is actually stability to microorganisms and enzymes, which can decrease the price 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 industry, manufacturing form goods are not only in order to let the mould release to improve productivity and extend the life of the cast use. And can make the product clear, size qualified, and lower the generation of scrap, that is an crucial additive essential to moulds and products – concrete additive.
Concrete release agent plays an essential role in modern building building; its main role is always to form a layer of separation motion picture between the template and the concrete area to ensure that the template does not stick to the concrete surface to ensure that it is much easier to take down the mould following flowing and to maintain the finish of the concrete area. Here, we will introduce the kinds, features, usage and program of concrete release agent in more detail.
Sorts of concrete release agent
Concrete release representatives can be divided into many sorts based on different classification strategies, and the common grouping 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 emission agent for tunnels and etc.
- According to the the composition: it can be divided into water-based concrete release agents, oil-based concrete release representatives, silicone oil concrete release representatives, etc.
- According to the use effect: it can be divided into ordinary concrete release representatives, easy-to-remove concrete release representatives, high-gloss concrete release agents and and so forth.
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 really a type of material coated on the inner wall of the formwork to play the function of lubricating and remoteness 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 standard release substance motor oil or waste motor oil, the release agent has the benefits of effortless release, no pollution of the concrete surface, no corrosion of the template, easy to paint, low cost and so on. However, not all types of concrete release agents with a variety of materials made of templates are suitable for different components of the template and different building circumstances 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 characteristics:
Good isolation overall performance: concrete release agent can develop a dense separation movie between the formwork and the concrete surface, successfully stopping the formwork from bonding with the concrete surface and facilitating the demolding.
Excellent lubrication efficiency: concrete release agent has good lubricating efficiency, which can reduce the friction between the formwork and concrete surface, decrease the resistance during pouring and boost the construction effectiveness.
Excellent anti-adhesion performance: concrete release agents can efficiently prevent the formwork from bonding with the concrete covering, steering clear of the formwork from damaging the concrete covering when dismantling the formwork.
Great waterproof efficiency: concrete release agent has good waterproof efficiency, which can effectively prevent 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 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 area.
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 surface 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 dismantling.
Clean up the template: after taking apart 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 representatives 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 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 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 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 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 crucial construction auxiliary material, plays an indispensable role in modern development projects. By choosing the right kind, 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 development of the construction industry.
