What is a concrete release agent?
A concrete release agent is actually a compound put on the building template prior to the concrete is added in order that the design does not stick to to the concrete surface right after putting, isn’t effortless to take down the mould or influences the complete of the concrete covering. Its main role within the design and the concrete covering to create a movie that is going to be separated from the two is also called an separation agent.
A water-based release agent is definitely an essential auxiliary inside the release agent and can modify the water-based release agent stream and levelling; its primary attribute is actually stability to microorganisms and enzymes, which can reduce the cost of raw materials. A water-based form release agent can be used in casts and goods functional processing ingredients; in the rubber, plastic, and Jinsu processing industry, manufacturing cast items are not just so as to let the cast release to improve productivity and lengthen the life of the mould utilize. And can make the item clear, size qualified, and decrease the generation of scrap, which can be an crucial additive essential to forms and items – concrete additive.
Concrete release agent plays an crucial role inside modern building construction; its primary role is always to develop a layer of isolation film between the template and the concrete area in order that the template will not stick to to the concrete covering in order that it is simpler to dismantle the mould following putting and to maintain the end of the concrete surface. Here, we will introduce the types, characteristics, usage and use of concrete release agent in detail.
Kinds of concrete release agent
Concrete release agents can be divided into several sorts in accordance with different classification methods, and the typical grouping 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 etc.
- According to the composition of: it can be divided into water-based concrete release brokers, oil-based concrete release representatives, silicone oil concrete release brokers, etc.
- According to the the utilization effect: it can be divided into ordinary concrete release agents, an easy task to remove concrete release agents, high-gloss concrete release representatives and and so forth.
Qualities of Concrete release agent
A concrete release agent is additionally referred to as a concrete separation agent or mould release lubricant. It is a sort of material coated on the inner wall of the formwork to play the part of lubrication and isolation to ensure that the concrete can be smoothly detached from the formwork when taking down the formwork, and the form of the concrete can be kept intact and undamaged. Compared with the standard release materials motor oil or waste motor oil, the release agent has the benefits of easy release, no pollution of the concrete covering, no corrosion of the template, easy to paint, low value and so on. However, not all kinds of concrete release agents with a array of components made of templates are suitable for different components of the template and different development problems and finish requirements of the concrete must be selected for the appropriate release agent in order to receive good results.
As an important construction auxiliary material, concrete release agent has the following features:
Good remoteness overall performance: concrete release agent can form a dense remoteness movie between the formwork and the concrete covering, efficiently stopping the formwork from bonding with the concrete area and facilitating the demolding.
Great lubrication performance: concrete release agent has good lubricating overall performance, which can reduce the rubbing between the formwork and concrete surface, reduce the resistance during pouring and boost the construction effectiveness.
Excellent anti-adhesion performance: concrete release agents can effectively stop the formwork from bonding with the concrete covering, preventing the formwork from damaging the concrete surface when dismantling the formwork.
Good waterproof efficiency: concrete release agent has good waterproof performance, which can effectively avoid 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 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 taking down 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 surface, tools can be used appropriately to assist in the dismantling.
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 development 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 improve 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 boost 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 development projects.
In conclusion, concrete release agent, as an important construction auxiliary material, plays an indispensable role in modern building 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 development project and provide a strong guarantee for the development of the development industry.
