What is a concrete release agent?
A concrete release agent is definitely a material put on the development template before the concrete is added so that the design does not adhere to the concrete area following flowing, is not simple to take down the cast or impacts the finish of the concrete surface. Its primary role in the design and the concrete surface to form a movie that will probably be separated from the two can also be called an separation agent.
A water-based release agent is definitely an crucial ancillary within the release agent and can modify the water-based release agent stream and levelling; its principal attribute is definitely stability to microorganisms and enzymes, which can decrease the expense of raw materials. A water-based cast release agent can be used in forms and goods functional processing additives; in the rubber, plastic, and Jinsu processing industry, manufacturing cast products are not just to be able to let the form release to enhance productivity and prolong the life of the cast make use of. And can make the merchandise thoroughly clean, size qualified, and reduce the generation of scrap, that is an important additional essential to moulds and products – concrete additive.
Concrete release agent plays an essential role within modern building development; its primary role would be to create a layer of remoteness movie between the template and the concrete surface in order that the template does not stick to the concrete area to ensure that it is simpler to take down the cast following pouring and to maintain the complete of the concrete covering. Here, we will unveil the kinds, features, use and use of concrete release agent in more detail.
Kinds of concrete release agent
Concrete release representatives can be divided into several sorts in accordance with different grouping methods, and the frequent classification strategies are the subsequent:
- According to the scope of use: it can be divided into concrete release agent for development, concrete release agent for bridges, concrete discharge agent for tunnels and and so forth.
- According to the composition: it can be divided into water-based concrete release agents, petroleum-based concrete release brokers, silicone oil concrete release representatives, etc.
- According to the the use effect: it can be divided into ordinary concrete release brokers, an easy task to remove concrete release agents, high-gloss concrete release brokers and and so forth.
Features of Concrete release agent
A concrete release agent is additionally referred to as a concrete remoteness agent or mould release lubricant. It is a sort of material coated on the inner wall of the formwork to play the function of lubrication and isolation so that the concrete can be smoothly detached from the formwork when taking apart the formwork, and the form of the concrete can be kept intact and undamaged. Compared with the standard release material motor oil or waste motor oil, the release agent has the benefits of effortless release, no pollution of the concrete surface, no corrosion of the template, simple to paint, low value and etc. However, not all types of concrete release agents with a selection of components made of templates are suitable for different components 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 next characteristics:
Good separation performance: concrete release agent can form a dense separation motion picture between the formwork and the concrete covering, successfully stopping the formwork from bonding with the concrete area and facilitating the demolding.
Great lubrication overall performance: concrete release agent has good lubrication efficiency, which can decrease the friction between the formwork and concrete covering, lower the resistance during pouring and improve the construction productivity.
Excellent anti-adhesion overall performance: concrete release representatives can efficiently avoid the formwork from bonding with the concrete area, avoiding the formwork from damaging the concrete area when taking down the formwork.
Great waterproof overall performance: concrete release agent has good waterproof overall performance, which can effectively stop moisture from penetrating between the formwork and concrete, avoiding deformation of the formwork by moisture and enhancing 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 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 surface.
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 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 construction projects, mainly including the following aspects:
Reinforced concrete structure: In the construction of a reinforced concrete structure, concrete release brokers can be used for formwork isolation, preventing 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 surface and enhance 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 construction projects.
In conclusion, concrete release agent, as an crucial 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 boost the construction efficiency and quality of the construction project and provide a strong guarantee for the advancement of the development industry.
