What is a concrete release agent?
A concrete release agent is definitely a substance put on the building template just before the concrete is poured in order that the template doesn’t adhere to the concrete area right after pouring, is not easy to take down the mould or impacts the complete of the concrete covering. Its main role within the design and the concrete covering to create a film that will be separated from the two is also called an isolation agent.
A water-based release agent is surely an important ancillary inside the release agent and can alter the water-based release agent circulation and levelling; its main feature is actually stability to microorganisms and enzymes, which can lower the expense of raw materials. A water-based cast release agent can be used in forms and items functional processing ingredients; in the rubber, plastic, and Jinsu processing business, manufacturing cast products are not just so as to let the form release to improve productivity and prolong the life of the mould utilize. And can make the product thoroughly clean, size qualified, and reduce the creation of scrap, which can be an important additional important to forms and goods – concrete additive.
Concrete release agent plays an crucial role in modern building development; its primary role is always to form a layer of separation motion picture between the template and the concrete covering to ensure that the design doesn’t adhere to the concrete covering to ensure that it is much easier to take apart the form right after flowing and to maintain the complete of the concrete covering. Here, we will introduce the types, features, usage and application of concrete release agent in detail.
Sorts of concrete release agent
Concrete release agents can be divided into numerous sorts in accordance with different category strategies, and the typical category methods are the following:
- According to the scope of use: it can be divided into concrete release agent for construction, concrete release agent for bridges, concrete launch agent for tunnels and so on.
- According to the composition: it can be divided into water-based concrete release representatives, oil-based concrete release brokers, silicone oil concrete release representatives, etc.
- According to the utilization effect: it can be divided into ordinary concrete release representatives, simple to remove concrete release agents, high-gloss concrete release representatives and so on.
Features of Concrete release agent
A concrete release agent is also called a concrete remoteness agent or mould release lubricant. It is actually a sort of material coated on the inner wall of the formwork to play the role of lubricating and isolation to ensure that the concrete could be easily detached from the formwork when dismantling the formwork, and the condition of the concrete may be kept intact and undamaged. Compared with the standard release materials motor oil or waste motor oil, the release agent has the positive aspects of effortless release, no pollution of the concrete covering, no corrosion of the template, easy to paint, low cost and so on. However, not all types of concrete release agents with a array of supplies made of templates are suitable for different materials of the template and different development problems and finish requirements of the concrete must be selected for the ideal release agent in order to receive good results.
As an essential construction auxiliary material, concrete release agent has the subsequent features:
Good remoteness overall performance: concrete release agent can create a dense remoteness film between the formwork and the concrete surface, efficiently preventing the formwork from bonding with the concrete surface and facilitating the demolding.
Great lubrication efficiency: concrete release agent has good lubrication overall performance, which can lower the rubbing between the formwork and concrete covering, lower the resistance during pouring and boost the construction effectiveness.
Good anti-adhesion efficiency: concrete release brokers can successfully avoid the formwork from bonding with the concrete area, avoiding the formwork from damaging the concrete surface when taking down the formwork.
Great waterproof performance: concrete release agent has good waterproof efficiency, which can successfully stop moisture from penetrating between the formwork and concrete, steering clear of deformation of the formwork by moisture and increasing the service life of the formwork.
Simple 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 taking down 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 surface gradually. In case of tight bonding between the formwork and the concrete surface, tools can be used appropriately to assist in the taking apart.
Clean up the template: after taking down 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, avoiding formwork from bonding with concrete and improving 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 area 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 agents 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 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 building project and provide a strong guarantee for the advancement of the building industry.
