What is a concrete release agent?
A concrete release agent is actually a substance placed on the development template prior to the concrete is poured so that the template will not adhere to the concrete surface after pouring, isn’t easy to take down the cast or influences the end of the concrete area. Its primary role inside the template and the concrete surface to develop a film that will be separated from the two can also be called an isolation agent.
A water-based release agent is definitely an important ancillary in the release agent and can modify the water-based release agent stream and levelling; its principal characteristic is definitely stability to microorganisms and enzymes, which can decrease the cost of raw materials. A water-based form release agent is used in moulds and products functional processing additives; in the rubber, plastic, and Jinsu processing market, manufacturing form goods are not only to be able to let the form release to enhance productivity and lengthen the life of the form make use of. And can make the merchandise clear, size qualified, and reduce the generation of scrap, which is an crucial additive vital to forms and items – concrete additive.
Concrete release agent plays an important role in modern building development; its principal role would be to form a layer of remoteness film between the template and the concrete surface so that the template does not stick to to the concrete covering in order that it is much easier to take down the cast right after putting and to maintain the complete of the concrete area. Here, we will present the sorts, features, usage and program of concrete release agent in detail.
Types of concrete release agent
Concrete release brokers can be divided into several types in accordance with different classification methods, and the common grouping methods are the following:
- According to the scope of use: it can be divided into concrete release agent for development, concrete release agent for bridges, concrete release agent for tunnels and and so forth.
- According to the the formula of: it can be divided into water-based concrete release brokers, oil-based concrete release agents, silicone oil concrete release brokers, etc.
- According to the use effect: it can be divided into ordinary concrete release agents, an easy task to remove concrete release agents, high-gloss concrete release brokers and and so forth.
Characteristics of Concrete release agent
A concrete release agent can also be called a concrete remoteness agent or mould release lubricant. It is really a type of substance coated on the inner wall of the formwork to play the part of lubrication and remoteness to ensure that the concrete may be effortlessly detached from the formwork when taking apart the formwork, and the shape of the concrete can be kept intact and undamaged. Compared with the conventional release material motor oil or waste motor oil, the release agent has the benefits of easy release, no pollution of the concrete covering, no corrosion of the template, easy to paint, low cost and and so forth. However, not all sorts of concrete release brokers with a selection of supplies 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 essential construction auxiliary material, concrete release agent has the following qualities:
Good remoteness overall performance: concrete release agent can create a dense remoteness movie between the formwork and the concrete surface, effectively stopping the formwork from bonding with the concrete area and facilitating the dismantling.
Good lubrication overall performance: concrete release agent has good lubrication efficiency, which can lower the chaffing between the formwork and concrete surface, lower the resistance during pouring and boost the construction productivity.
Great anti-adhesion overall performance: concrete release brokers can successfully stop the formwork from bonding with the concrete surface, avoiding the formwork from damaging the concrete area when taking down the formwork.
Excellent waterproof overall performance: concrete release agent has good waterproof performance, which can effectively avoid moisture from penetrating between the formwork and concrete, avoiding deformation of the formwork by moisture and improving the service life of the formwork.
Easy 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 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 dismantling 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 covering 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 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 construction projects, mainly including the following aspects:
Reinforced concrete structure: In the building of a reinforced concrete structure, concrete release representatives can be used for formwork isolation, avoiding 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 area 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 construction projects.
In conclusion, concrete release agent, as an important 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 improve the construction efficiency and quality of the building project and provide a strong guarantee for the development of the development industry.
