What exactly is a concrete release agent?
A concrete release agent is a material put on the development template prior to the concrete is put so the template will not stick to to the concrete surface right after pouring, is not easy to take down the form or influences the end of the concrete surface. Its primary role inside the template and the concrete area to form a motion picture that will be separated from the two is additionally referred to as an remoteness agent.
A water-based release agent is surely an crucial ancillary inside the release agent and can modify the water-based release agent stream and levelling; its main feature is actually stability to microorganisms and enzymes, which can lower the cost of raw materials. A water-based form release agent can be used in moulds and products functional processing supplements; in the rubber, plastic, and Jinsu processing industry, manufacturing cast products are not only so as to let the mould release to enhance productivity and prolong the life of the cast utilize. And can make the item thoroughly clean, size qualified, and lower the technology of scrap, which can be an essential additive important to moulds and products – concrete release agent.
Concrete release agent plays an important role within modern building construction; its principal role is to form a layer of isolation film between the template and the concrete surface to ensure that the template doesn’t adhere to the concrete covering so that it is easier to take down the cast after putting and to maintain the complete of the concrete surface. Here, we will unveil the sorts, features, use and program of concrete release agent in detail.
Types of concrete release agent
Concrete release agents can be divided into several kinds in accordance with different grouping methods, and the frequent classification methods are as follows:
- According to the the scope of use: it can be divided into concrete release agent for development, 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 agents, oil-based concrete release representatives, silicone oil concrete release brokers, etc.
- According to the the use effect: it can be divided into ordinary concrete release representatives, easy-to-remove concrete release representatives, high-gloss concrete release brokers 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 type of material coated on the inner wall of the formwork to play the role of lubrication and remoteness to ensure that the concrete can be smoothly detached from the formwork when taking apart the formwork, and the shape of the concrete could be kept intact and undamaged. Compared with the traditional release material motor oil or waste motor oil, the release agent has the advantages of easy release, no pollution of the concrete covering, no corrosion of the template, simple to paint, low price and so on. However, not all types of concrete release representatives with a selection of components made of templates are suitable for different materials of the template and different building circumstances 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 subsequent characteristics:
Good remoteness efficiency: concrete release agent can develop a dense separation movie between the formwork and the concrete area, efficiently stopping the formwork from bonding with the concrete covering and facilitating the demolding.
Good lubrication efficiency: concrete release agent has good lubricating efficiency, which can decrease the rubbing between the formwork and concrete area, decrease the resistance during pouring and enhance the construction productivity.
Good anti-adhesion performance: concrete release representatives can successfully prevent the formwork from bonding with the concrete covering, avoiding the formwork from damaging the concrete surface when taking apart 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.
Easy 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 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 covering.
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 surface gradually. In case of tight bonding between the formwork and the concrete surface, tools can be used appropriately to assist in the taking down.
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 building of a reinforced concrete structure, concrete release brokers 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 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 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 enhance 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 essential construction auxiliary material, plays an indispensable role in modern development projects. By choosing the right sort, the correct use method and a reasonable application field, can effectively improve the construction efficiency and quality of the development project and provide a strong guarantee for the development of the building industry.
