What is actually a concrete release agent?
A concrete release agent is a substance put on the development template before the concrete is put in order that the template will not adhere to the concrete covering after putting, is not easy to take apart the cast or impacts the finish of the concrete covering. Its main role inside the template and the concrete surface to create a film that is going to be separated from the two is also known as an separation agent.
A water-based release agent is definitely an essential ancillary inside the release agent and can alter the water-based release agent stream and levelling; its primary attribute is definitely stability to microorganisms and enzymes, which can decrease the expense of raw materials. A water-based form release agent is used in casts and items functional processing supplements; in the rubber, plastic, and Jinsu processing market, manufacturing form goods are not just so as to let the form release to improve productivity and lengthen the life of the cast use. And can make the item thoroughly clean, size qualified, and decrease the generation of scrap, that is an essential additional vital to forms and goods – Water-based Concrete Release Agent.
Concrete release agent plays an essential role in modern building development; its main role is to develop a layer of separation motion picture between the template and the concrete surface to ensure that the template does not stick to to the concrete covering in order that it is much easier to take apart the mould following pouring and to maintain the finish of the concrete covering. Here, we will present the types, qualities, use and application of concrete release agent in detail.
Kinds of concrete release agent
Concrete release brokers can be divided into several sorts according to different classification methods, and the frequent category 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 discharge agent for tunnels and and so forth.
- According to the formula of: it can be divided into water-based concrete release representatives, oil-based concrete release agents, silicone oil concrete release agents, etc.
- According to the the effect of use: it can be divided into ordinary concrete release brokers, simple to remove concrete release agents, high-gloss concrete release representatives and and so forth.
Features of Concrete release agent
A concrete release agent is also called a concrete isolation agent or mould release lubricant. It is really a kind of material coated on the inner wall of the formwork to play the part of lubricating and remoteness in order that the concrete could be smoothly detached from the formwork when dismantling the formwork, and the condition of the concrete could be kept intact and undamaged. Compared with the standard release substance motor oil or waste motor oil, the release agent has the advantages of effortless release, no pollution of the concrete covering, no corrosion of the template, simple to paint, low cost and so on. However, not all kinds of concrete release agents with a variety of materials made of templates are suitable for different supplies of the template and different construction problems 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 following qualities:
Good isolation overall performance: concrete release agent can create a dense isolation movie between the formwork and the concrete area, efficiently avoiding the formwork from bonding with the concrete covering and facilitating the demolding.
Excellent lubrication efficiency: concrete release agent has good lubricating overall performance, which can reduce the chaffing between the formwork and concrete area, reduce the resistance during pouring and improve the construction efficiency.
Excellent anti-adhesion performance: concrete release brokers can effectively avoid the formwork from bonding with the concrete area, avoiding the formwork from damaging the concrete area when taking apart the formwork.
Excellent waterproof performance: concrete release agent has good waterproof efficiency, which can successfully avoid 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 effortless 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 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 area gradually. In case of tight bonding between the formwork and the concrete surface, tools can be used appropriately to assist in the dismantling.
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 development of a reinforced concrete structure, concrete release representatives 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 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 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 development 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 building project and provide a strong guarantee for the advancement of the construction industry.
