What exactly is a concrete release agent?
A concrete release agent is definitely a material applied to the development template just before the concrete is put so the design will not stick to the concrete covering right after pouring, is not easy to take down the cast or impacts the complete of the concrete area. Its primary role within the design and the concrete covering to develop a film that will be separated from the two is additionally referred to as an separation agent.
A water-based release agent is surely an crucial auxiliary inside the release agent and can modify the water-based release agent circulation and levelling; its main characteristic is actually stability to microorganisms and enzymes, which can lower the expense of raw materials. A water-based mould release agent can be used in moulds and items functional processing additives; in the rubber, plastic, and Jinsu processing market, manufacturing cast products are not only in order to let the cast release to boost productivity and extend the life of the form use. And can make the item thoroughly clean, size qualified, and lower the technology of scrap, which can be an crucial additive important to casts and goods – concrete additive.
Concrete release agent plays an essential role within modern building building; its principal role is always to develop a layer of separation motion picture between the template and the concrete surface in order that the template doesn’t adhere to the concrete area to ensure that it is much easier to take apart the cast right after flowing and to maintain the finish of the concrete area. Here, we will present the sorts, features, use and program of concrete release agent in more detail.
Types of concrete release agent
Concrete release brokers can be divided into numerous types in accordance with different classification techniques, and the typical category strategies are as follows:
- According to the scope of use: it can be divided into concrete release agent for building, concrete release agent for bridges, concrete emission agent for tunnels and so on.
- According to the the composition: it can be divided into water-based concrete release representatives, petroleum-based concrete release agents, silicone oil concrete release representatives, etc.
- According to the the utilization effect: it can be divided into ordinary concrete release agents, an easy task to remove concrete release representatives, high-gloss concrete release brokers and etc.
Features of Concrete release agent
A concrete release agent is additionally called a concrete isolation agent or mould release lubricant. It is actually a type of compound coated on the inner wall of the formwork to play the role of lubricating and remoteness in order that the concrete can be easily detached from the formwork when taking down the formwork, and the form of the concrete may be kept intact and undamaged. Compared with the traditional 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, easy to paint, low cost and and so forth. However, not all kinds of concrete release representatives with a selection of components made of templates are suitable for different components of the template and different development 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 following characteristics:
Good isolation performance: concrete release agent can develop a dense remoteness film between the formwork and the concrete covering, efficiently stopping the formwork from bonding with the concrete surface and facilitating the dismantling.
Great lubrication performance: concrete release agent has good lubrication 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 overall performance: concrete release agents can effectively avoid the formwork from bonding with the concrete covering, avoiding the formwork from damaging the concrete surface when taking apart the formwork.
Great waterproof overall performance: concrete release agent has good waterproof performance, 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.
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 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 area gradually. In case of tight bonding between the formwork and the concrete area, tools can be used appropriately to assist in the taking apart.
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 development projects, mainly including the following aspects:
Reinforced concrete structure: In the construction of a reinforced concrete structure, concrete release representatives can be used for formwork isolation, stopping 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 covering, 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 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 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 crucial construction auxiliary material, plays an indispensable role in modern construction projects. By choosing the right type, the correct use method and a reasonable application field, can effectively enhance the construction efficiency and quality of the building project and provide a strong guarantee for the advancement of the construction industry.
