What is actually a concrete release agent?
A concrete release agent is actually a material put on the construction template just before the concrete is added in order that the design does not stick to to the concrete covering right after putting, is just not effortless to take apart the mould or impacts the end of the concrete covering. Its principal role within the design and the concrete covering to create a film that is going to be separated from the two is additionally called an separation agent.
A water-based release agent is surely an crucial ancillary in the release agent and can change the water-based release agent stream and levelling; its principal attribute is actually stability to microorganisms and enzymes, which can reduce the price of raw materials. A water-based form release agent is used in forms and items functional processing supplements; in the rubber, plastic, and Jinsu processing market, manufacturing mould goods aren’t just so as to let the form release to improve productivity and prolong the life of the cast use. And can make the merchandise clear, size qualified, and lower the generation of scrap, which is an important additive vital to moulds and items – Water-based Concrete Release Agent.
Concrete release agent plays an crucial role in modern building building; its principal role is to develop a layer of separation motion picture between the design and the concrete surface so that the design does not stick to to the concrete area to ensure that it is easier to dismantle the form after flowing and to maintain the complete of the concrete covering. Here, we will introduce the types, features, utilization and use of concrete release agent at length.
Kinds of concrete release agent
Concrete release representatives can be divided into several types according to different category methods, and the common classification methods 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 discharge agent for tunnels and and so forth.
- According to the composition of: it can be divided into water-based concrete release agents, petroleum-based concrete release brokers, silicone oil concrete release representatives, etc.
- According to the utilization effect: it can be divided into ordinary concrete release representatives, easy-to-remove concrete release representatives, high-gloss concrete release representatives and etc.
Characteristics of Concrete release agent
A concrete release agent is additionally referred to as a concrete separation agent or mould release lubricant. It is really a sort of compound coated on the inner wall of the formwork to play the role of lubrication and separation to ensure that the concrete could be smoothly detached from the formwork when taking down the formwork, and the form of the concrete could be kept intact and undamaged. Compared with the standard release materials 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 and so forth. However, not all kinds of concrete release agents with a array of supplies 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 appropriate release agent in order to receive good results.
As an essential construction auxiliary material, concrete release agent has the next qualities:
Good isolation overall performance: concrete release agent can form a dense separation motion picture between the formwork and the concrete area, efficiently stopping the formwork from bonding with the concrete area and facilitating the removing.
Good lubrication efficiency: concrete release agent has good lubrication efficiency, which can lower the chaffing between the formwork and concrete covering, lower the resistance during pouring and enhance the construction effectiveness.
Great anti-adhesion performance: concrete release agents can efficiently stop the formwork from bonding with the concrete area, steering clear of the formwork from damaging the concrete covering when dismantling the formwork.
Good waterproof overall performance: concrete release agent has good waterproof overall performance, which can successfully stop moisture from penetrating between the formwork and concrete, steering clear of deformation of the formwork by moisture and improving 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 oil-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 apart 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 covering, tools can be used appropriately to assist in the taking apart.
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 agents can be used for formwork isolation, stopping formwork from bonding with concrete and increasing 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 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 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 important construction auxiliary material, plays an indispensable role in modern building projects. By choosing the right type, the correct use method and a reasonable application field, can effectively improve the construction efficiency and quality of the construction project and provide a strong guarantee for the growth of the development industry.
