What is a concrete release agent?
A concrete release agent is definitely a compound placed on the development template prior to the concrete is added so the template does not stick to the concrete surface after putting, is just not easy to dismantle the cast or affects the complete of the concrete area. Its main role inside the template and the concrete surface to form a film that will probably be separated from the two is additionally known as an isolation agent.
A water-based release agent is definitely an essential auxiliary within the release agent and can alter the water-based release agent circulation and levelling; its primary characteristic is actually stability to microorganisms and enzymes, which can decrease the cost of raw materials. A water-based form release agent is used in forms and goods functional processing additives; in the rubber, plastic, and Jinsu processing industry, manufacturing mould goods are not just so as to let the form release to enhance productivity and extend the life of the mould utilize. And can make the product thoroughly clean, size qualified, and lower the technology of scrap, which can be an crucial additive vital to casts and items – concrete additive.
Concrete release agent plays an important role within modern building development; its principal role is always to develop a layer of remoteness motion picture between the design and the concrete area to ensure that the design doesn’t stick to to the concrete covering so that it is easier to dismantle the cast right after flowing and to maintain the end of the concrete area. Here, we will introduce the sorts, characteristics, use and application of concrete release agent in more detail.
Sorts of concrete release agent
Concrete release agents can be divided into many kinds based on different classification strategies, and the typical classification techniques 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 launch agent for tunnels and so on.
- According to the composition: it can be divided into water-based concrete release representatives, oil-based concrete release brokers, silicone oil concrete release agents, etc.
- According to the the use effect: it can be divided into ordinary concrete release brokers, simple to remove concrete release agents, high-gloss concrete release brokers and etc.
Characteristics of Concrete release agent
A concrete release agent can also be known as a concrete isolation agent or mould release lubricant. It is actually a kind of material coated on the inner wall of the formwork to play the role of lubricating and remoteness to ensure that the concrete may be smoothly detached from the formwork when dismantling the formwork, and the form of the concrete can be kept intact and undamaged. Compared with the conventional release substance motor oil or waste motor oil, the release agent has the advantages of simple release, no pollution of the concrete area, no corrosion of the template, effortless to paint, low value and etc. However, not all kinds of concrete release brokers with a array of components made of templates are suitable for different supplies of the template and different building problems 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 next qualities:
Good remoteness performance: concrete release agent can develop a dense isolation movie between the formwork and the concrete area, successfully preventing the formwork from bonding with the concrete area and facilitating the dismantling.
Excellent lubrication overall performance: concrete release agent has good lubricating performance, which can lower the friction between the formwork and concrete surface, decrease the resistance during pouring and boost the construction efficiency.
Good anti-adhesion efficiency: concrete release representatives can successfully avoid the formwork from bonding with the concrete surface, avoiding the formwork from damaging the concrete surface when taking apart the formwork.
Excellent waterproof performance: concrete release agent has good waterproof performance, which can effectively stop moisture from penetrating between the formwork and concrete, avoiding deformation of the formwork by moisture and increasing 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 taking down 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 surface gradually. In case of tight bonding between the formwork and the concrete covering, 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 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, 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 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 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 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 building 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 construction project and provide a strong guarantee for the growth of the development industry.
