What is actually a concrete release agent?
A concrete release agent is definitely a compound applied to the building design just before the concrete is put so the design does not stick to the concrete surface right after putting, is not simple to take apart the mould or influences the finish of the concrete covering. Its primary role inside the template and the concrete area to create a motion picture that will be separated from the two can also be known as an separation agent.
A water-based release agent is surely an important ancillary within the release agent and can alter the water-based release agent stream and levelling; its primary feature is definitely stability to microorganisms and enzymes, which can lower the expense of raw materials. A water-based cast release agent is used in forms and products functional processing additives; in the rubber, plastic, and Jinsu processing market, manufacturing mould items are not only to be able to let the mould release to boost productivity and prolong the life of the cast make use of. And can make the product clear, size qualified, and reduce the generation of scrap, that is an crucial additional important to casts and goods – concrete release agent.
Concrete release agent plays an crucial role inside modern building development; its primary role would be to develop a layer of separation film between the template and the concrete area so that the template doesn’t adhere to the concrete area in order that it is much easier to dismantle the mould after pouring and to maintain the end of the concrete covering. Here, we will present the kinds, qualities, usage and program of concrete release agent in more detail.
Kinds of concrete release agent
Concrete release brokers can be divided into many sorts according to different category strategies, and the common classification strategies are the following:
- According to 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 etc.
- According to the composition: it can be divided into water-based concrete release representatives, petroleum-based concrete release agents, silicone oil concrete release brokers, etc.
- According to the the effect of use: it can be divided into ordinary concrete release brokers, easy-to-remove concrete release brokers, high-gloss concrete release brokers and so on.
Qualities of Concrete release agent
A concrete release agent can also be 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 part of lubricating and separation to ensure that the concrete can be easily detached from the formwork when taking down the formwork, and the condition of the concrete can be kept intact and undamaged. Compared with the standard release materials motor oil or waste motor oil, the release agent has the benefits of simple release, no pollution of the concrete surface, no corrosion of the template, effortless to paint, low value and so on. However, not all sorts of concrete release agents with a variety of materials made of templates are suitable for different materials of the template and different development conditions and finish requirements of the concrete must be selected for the suitable release agent in order to receive good results.
As an crucial construction auxiliary material, concrete release agent has the next features:
Good isolation performance: concrete release agent can form a dense separation film between the formwork and the concrete surface, successfully stopping the formwork from bonding with the concrete area and facilitating the demolding.
Excellent lubrication efficiency: concrete release agent has good lubrication performance, which can lower the chaffing between the formwork and concrete covering, decrease the resistance during pouring and improve the construction productivity.
Great anti-adhesion performance: concrete release agents can effectively stop the formwork from bonding with the concrete covering, steering clear of the formwork from damaging the concrete covering when dismantling the formwork.
Great waterproof performance: concrete release agent has good waterproof performance, which can effectively 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.
Simple 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 covering 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 down 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 development 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 area, 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 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 agents 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 kind, the correct use method and a reasonable application field, can effectively enhance the construction efficiency and quality of the development project and provide a strong guarantee for the advancement of the building industry.
