What is actually a concrete release agent?
A concrete release agent is a compound applied to the development template just before the concrete is added in order that the design doesn’t stick to to the concrete area right after pouring, isn’t easy to dismantle the cast or affects the end of the concrete area. Its primary role inside the template and the concrete covering to create a film that will be separated from the two is additionally referred to as an separation agent.
A water-based release agent is an essential supplementary within the release agent and can change the water-based release agent stream and levelling; its primary characteristic 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 items functional processing ingredients; in the rubber, plastic, and Jinsu processing industry, manufacturing cast items are not just to be able to let the mould release to improve productivity and prolong the life of the mould make use of. And can make the merchandise clear, size qualified, and decrease the creation of scrap, which is an essential additive important to forms and products – concrete release agent.
Concrete release agent plays an essential role in modern building construction; its main role would be to form a layer of isolation motion picture between the template and the concrete surface to ensure that the design doesn’t stick to the concrete surface in order that it is simpler to take down the mould after putting and to maintain the end of the concrete area. Here, we will unveil the kinds, qualities, use and program of concrete release agent in detail.
Types of concrete release agent
Concrete release representatives can be divided into numerous types according to different grouping techniques, and the typical classification techniques are the following:
- According to the the opportunity of use: it can be divided into concrete release agent for construction, concrete release agent for bridges, concrete emission agent for tunnels and so on.
- According to the composition of: it can be divided into water-based concrete release representatives, petroleum-based concrete release representatives, silicone oil concrete release brokers, etc.
- According to the the use effect: 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 is additionally known as a concrete isolation agent or mould release lubricant. It is really a kind of compound coated on the inner wall of the formwork to play the function of lubrication and remoteness to ensure that the concrete may be easily detached from the formwork when taking down the formwork, and the shape of the concrete could be kept intact and undamaged. Compared with the traditional release materials motor oil or waste motor oil, the release agent has the benefits of easy release, no pollution of the concrete area, no corrosion of the template, easy to paint, low value and so on. However, not all types of concrete release representatives with a array of supplies made of templates are suitable for different components of the template and different building problems and finish requirements of the concrete must be selected for the ideal release agent in order to receive good results.
As an crucial construction auxiliary material, concrete release agent has the next features:
Good isolation performance: concrete release agent can form a dense isolation movie between the formwork and the concrete area, effectively stopping the formwork from bonding with the concrete area and facilitating the removing.
Great lubrication performance: concrete release agent has good lubrication overall performance, which can decrease the rubbing between the formwork and concrete area, reduce the resistance during pouring and improve the construction efficiency.
Great anti-adhesion efficiency: concrete release brokers can efficiently avoid the formwork from bonding with the concrete covering, avoiding the formwork from damaging the concrete surface when dismantling the formwork.
Excellent waterproof efficiency: concrete release agent has good waterproof performance, which can successfully stop 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 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 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 taking apart 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 building projects, mainly including the following aspects:
Reinforced concrete structure: In the development of a reinforced concrete structure, concrete release representatives 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 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 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 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 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 essential construction auxiliary material, plays an indispensable role in modern building 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 development project and provide a strong guarantee for the advancement of the building industry.
