What is actually a concrete release agent?
A concrete release agent is a substance placed on the development template before the concrete is poured so the template will not adhere to the concrete surface right after pouring, is just not easy to take down the form or affects the complete of the concrete surface. Its principal role within the design and the concrete area to form a movie that is going to be separated from the two is additionally called an separation agent.
A water-based release agent is an crucial supplementary within the release agent and can modify the water-based release agent circulation and levelling; its main attribute is definitely stability to microorganisms and enzymes, which can lower the price of raw materials. A water-based form release agent is used in forms and products functional processing additives; in the rubber, plastic, and Jinsu processing market, manufacturing form items aren’t just in order to let the form release to improve productivity and lengthen the life of the cast make use of. And can make the merchandise thoroughly clean, size qualified, and reduce the generation of scrap, which can be an crucial supplementary important to moulds and items – Water-based Concrete Release Agent.
Concrete release agent plays an crucial role inside modern building development; its main role would be to develop a layer of remoteness film between the design and the concrete area to ensure that the template doesn’t adhere to the concrete covering to ensure that it is much easier to take apart the cast following putting and to maintain the finish of the concrete area. Here, we will introduce the kinds, qualities, utilization and program of concrete release agent in detail.
Kinds of concrete release agent
Concrete release brokers can be divided into numerous kinds based on different category 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 formula of: it can be divided into water-based concrete release agents, oil-based concrete release agents, silicone oil concrete release representatives, etc.
- According to the effect of use: it can be divided into ordinary concrete release brokers, simple to remove concrete release agents, high-gloss concrete release brokers and and so forth.
Features of Concrete release agent
A concrete release agent can also be referred to as a concrete isolation agent or mould release lubricant. It is a type of compound coated on the inner wall of the formwork to play the function of lubricating and remoteness to ensure that the concrete can be easily detached from the formwork when taking down the formwork, and the condition of the concrete can be kept intact and undamaged. Compared with the traditional release material 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 etc. However, not all kinds of concrete release agents with a array of supplies made of templates are suitable for different materials 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 crucial construction auxiliary material, concrete release agent has the subsequent features:
Good remoteness efficiency: concrete release agent can develop a dense remoteness film between the formwork and the concrete covering, effectively stopping the formwork from bonding with the concrete surface and facilitating the demolding.
Good lubrication performance: concrete release agent has good lubricating performance, which can lower the friction between the formwork and concrete covering, reduce the resistance during pouring and enhance the construction productivity.
Good anti-adhesion efficiency: concrete release agents can successfully prevent the formwork from bonding with the concrete covering, preventing the formwork from damaging the concrete covering when dismantling the formwork.
Excellent waterproof efficiency: concrete release agent has good waterproof overall performance, which can effectively prevent 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 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 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 covering 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 down.
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 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 enhancing 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 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 building 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 boost the construction efficiency and quality of the construction project and provide a strong guarantee for the advancement of the construction industry.
