What is actually a concrete release agent?
A concrete release agent is a material put on the building design prior to the concrete is added so that the template doesn’t stick to the concrete area right after putting, is not easy to take apart the mould or influences the complete of the concrete covering. Its primary role inside the design and the concrete area to form a motion picture that is going to be separated from the two can also be called an isolation agent.
A water-based release agent is definitely an important auxiliary within the release agent and can alter 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 mould release agent is utilized in casts and items functional processing supplements; in the rubber, plastic, and Jinsu processing industry, manufacturing cast items aren’t just in order to let the cast release to improve productivity and prolong the life of the form use. And can make the merchandise clear, size qualified, and reduce the creation of scrap, which can be an essential additional essential to casts and goods – concrete additive.
Concrete release agent plays an essential role within modern building building; its main role would be to form a layer of separation motion picture between the design and the concrete area in order that the template doesn’t adhere to the concrete covering so that it is much easier to take down the mould following pouring and to maintain the complete of the concrete area. Here, we will unveil the kinds, characteristics, use and application of concrete release agent in more detail.
Kinds of concrete release agent
Concrete release representatives can be divided into numerous types in accordance with different category methods, and the typical category techniques are the subsequent:
- According to the opportunity of use: it can be divided into concrete release agent for development, concrete release agent for bridges, concrete launch agent for tunnels and so on.
- According to the the composition: it can be divided into water-based concrete release representatives, oil-based concrete release brokers, silicone oil concrete release brokers, etc.
- According to the the use effect: it can be divided into ordinary concrete release brokers, easy-to-remove concrete release agents, high-gloss concrete release brokers and so on.
Characteristics of Concrete release agent
A concrete release agent is also known as a concrete isolation agent or mould release lubricant. It is really a sort of substance coated on the inner wall of the formwork to play the part of lubricating and remoteness so that the concrete could be effortlessly 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 positive aspects 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 kinds of concrete release agents with a array of materials 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 appropriate release agent in order to receive good results.
As an important construction auxiliary material, concrete release agent has the next characteristics:
Good isolation performance: concrete release agent can create a dense isolation motion picture between the formwork and the concrete covering, successfully preventing the formwork from bonding with the concrete area and facilitating the removing.
Great lubrication performance: concrete release agent has good lubrication overall performance, which can reduce the rubbing between the formwork and concrete area, decrease the resistance during pouring and boost the construction effectiveness.
Great anti-adhesion overall performance: concrete release representatives can successfully prevent the formwork from bonding with the concrete area, avoiding the formwork from damaging the concrete area when dismantling the formwork.
Excellent waterproof overall performance: concrete release agent has good waterproof efficiency, which can efficiently stop 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.
Easy 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 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 surface 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 covering, tools can be used appropriately to assist in the taking down.
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 development projects, mainly including the following aspects:
Reinforced concrete structure: In the construction of a reinforced concrete structure, concrete release agents can be used for formwork isolation, avoiding 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 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 area 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 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 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 growth of the development industry.
