What is actually a concrete release agent?
A concrete release agent is actually a substance placed on the development template prior to the concrete is added in order that the template does not stick to to the concrete surface after pouring, isn’t easy to dismantle the cast or influences the complete of the concrete surface. Its main role in the template and the concrete covering to create a movie that will be separated from the two is additionally known as an separation agent.
A water-based release agent is surely an crucial ancillary within the release agent and can change the water-based release agent stream and levelling; its primary attribute is actually stability to microorganisms and enzymes, which can decrease the cost of raw materials. A water-based mould release agent is utilized in moulds and goods functional processing supplements; in the rubber, plastic, and Jinsu processing business, manufacturing form goods are not just to be able to let the cast release to boost productivity and extend the life of the mould use. And can make the item clear, size qualified, and decrease the creation of scrap, which is an important additive vital to moulds and items – concrete release agent.
Concrete release agent plays an essential role in modern building development; its primary role is to form a layer of separation film between the template and the concrete surface to ensure that the design doesn’t adhere to the concrete area so that it is simpler to take down the mould following flowing and to maintain the finish of the concrete area. Here, we will introduce the kinds, qualities, usage and application of concrete release agent in more detail.
Sorts of concrete release agent
Concrete release representatives can be divided into numerous kinds according to different classification techniques, and the frequent classification 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 emission agent for tunnels and etc.
- According to the 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 use effect: it can be divided into ordinary concrete release brokers, easy-to-remove concrete release representatives, high-gloss concrete release brokers and and so forth.
Characteristics of Concrete release agent
A concrete release agent is additionally referred to as a concrete isolation agent or mould release lubricant. It is actually a sort of material coated on the inner wall of the formwork to play the part of lubricating and separation to ensure that the concrete can be easily detached from the formwork when dismantling the formwork, and the condition of the concrete can be kept intact and undamaged. Compared with the conventional release substance motor oil or waste motor oil, the release agent has the advantages of simple release, no pollution of the concrete covering, no corrosion of the template, simple to paint, low cost and and so forth. However, not all types of concrete release representatives with a selection 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 appropriate release agent in order to receive good results.
As an essential construction auxiliary material, concrete release agent has the following qualities:
Good remoteness efficiency: concrete release agent can create a dense isolation movie between the formwork and the concrete surface, effectively stopping the formwork from bonding with the concrete area and facilitating the demolding.
Excellent lubrication overall performance: concrete release agent has good lubricating efficiency, which can decrease the friction between the formwork and concrete area, decrease the resistance during pouring and boost the construction productivity.
Excellent anti-adhesion efficiency: concrete release agents can successfully avoid the formwork from bonding with the concrete area, avoiding the formwork from damaging the concrete surface when dismantling the formwork.
Excellent waterproof performance: concrete release agent has good waterproof performance, which can successfully prevent moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and increasing the service life of the formwork.
Effortless 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 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 area.
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 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 building of a reinforced concrete structure, concrete release agents can be used for formwork isolation, stopping 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 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 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 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 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 building 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 construction industry.
