What is a concrete release agent?
A concrete release agent is definitely a substance put on the building design before the concrete is put so that the template doesn’t adhere to the concrete surface right after putting, is just not effortless to dismantle the cast or affects the end of the concrete surface. Its principal role inside the template and the concrete covering to create a movie that is going to be separated from the two is also called an remoteness agent.
A water-based release agent is surely an essential supplementary within the release agent and can alter the water-based release agent circulation and levelling; its primary attribute is actually stability to microorganisms and enzymes, which can lower the cost of raw materials. A water-based cast release agent is used in forms and goods functional processing ingredients; in the rubber, plastic, and Jinsu processing industry, manufacturing form products are not only to be able to let the mould release to boost productivity and extend the life of the cast use. And can make the merchandise thoroughly clean, size qualified, and decrease the generation of scrap, which can be an essential additive vital to casts and goods – concrete release agent.
Concrete release agent plays an essential role in modern building development; its main role is always to form a layer of remoteness motion picture between the template and the concrete surface so that the template doesn’t adhere to the concrete surface in order that it is easier to dismantle the mould after pouring and to maintain the finish of the concrete area. Here, we will present the kinds, characteristics, use and program of concrete release agent in more detail.
Sorts of concrete release agent
Concrete release agents can be divided into many types based on different grouping strategies, and the typical category methods are as follows:
- According to the 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 etc.
- According to the formula of: it can be divided into water-based concrete release agents, petroleum-based concrete release agents, silicone oil concrete release representatives, etc.
- According to the the effect of use: it can be divided into ordinary concrete release representatives, an easy task to remove concrete release brokers, high-gloss concrete release agents and and so forth.
Features of Concrete release agent
A concrete release agent is also called a concrete isolation agent or mould release lubricant. It is a type of material coated on the inner wall of the formwork to play the role of lubricating and separation in order that the concrete may be easily detached from the formwork when taking apart the formwork, and the form of the concrete may be kept intact and undamaged. Compared with the conventional release substance 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, effortless to paint, low value and so on. However, not all types of concrete release representatives with a selection of materials made of templates are suitable for different supplies of the template and different building 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 subsequent characteristics:
Good isolation overall performance: concrete release agent can form a dense remoteness motion picture between the formwork and the concrete covering, successfully preventing the formwork from bonding with the concrete covering and facilitating the removing.
Excellent lubrication efficiency: concrete release agent has good lubricating overall performance, which can lower the rubbing between the formwork and concrete area, reduce the resistance during pouring and improve the construction effectiveness.
Great anti-adhesion efficiency: concrete release agents can successfully stop the formwork from bonding with the concrete surface, preventing the formwork from damaging the concrete area when taking apart the formwork.
Great waterproof overall performance: concrete release agent has good waterproof overall performance, which can successfully prevent moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and enhancing the service life of the formwork.
Effortless 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 down 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 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 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 building of a reinforced concrete structure, concrete release representatives can be used for formwork isolation, avoiding 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 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 building projects.
In conclusion, concrete release agent, as an essential 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 building project and provide a strong guarantee for the advancement of the construction industry.
