What is a concrete release agent?
A concrete release agent is a material placed on the building design before the concrete is poured so the template will not stick to to the concrete area after flowing, isn’t easy to dismantle the cast or affects the complete of the concrete area. Its primary role within the design and the concrete surface to create a motion picture that is going to be separated from the two is additionally known as an separation agent.
A water-based release agent is an essential auxiliary inside the release agent and can modify the water-based release agent flow and levelling; its principal feature is stability to microorganisms and enzymes, which can lower the price of raw materials. A water-based form release agent is used in forms and products functional processing ingredients; in the rubber, plastic, and Jinsu processing business, manufacturing mould goods are not only in order to let the mould release to enhance productivity and prolong the life of the cast utilize. And can make the item clean, size qualified, and decrease the creation of scrap, which can be an essential supplementary essential to moulds and goods – concrete release agent.
Concrete release agent plays an important role within modern building construction; its primary role is always to develop a layer of remoteness film between the template and the concrete area so that the template will not stick to the concrete surface to ensure that it is simpler to dismantle the mould right after pouring and to maintain the complete of the concrete surface. Here, we will present the sorts, characteristics, use and use of concrete release agent in more detail.
Sorts of concrete release agent
Concrete release representatives can be divided into numerous types in accordance with different category techniques, and the common grouping 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 etc.
- According to the composition of: it can be divided into water-based concrete release brokers, petroleum-based concrete release representatives, silicone oil concrete release agents, etc.
- According to the utilization effect: it can be divided into ordinary concrete release brokers, easy-to-remove concrete release agents, high-gloss concrete release representatives and so on.
Characteristics of Concrete release agent
A concrete release agent is additionally called a concrete remoteness agent or mould release lubricant. It is really a sort of substance coated on the inner wall of the formwork to play the role of lubrication and separation so that the concrete may be effortlessly detached from the formwork when taking down 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 advantages of easy release, no pollution of the concrete area, no corrosion of the template, effortless to paint, low cost and and so forth. However, not all kinds of concrete release agents with a variety of materials made of templates are suitable for different supplies 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 following features:
Good separation efficiency: concrete release agent can form a dense separation motion picture between the formwork and the concrete covering, effectively stopping the formwork from bonding with the concrete surface and facilitating the removing.
Excellent lubrication overall performance: concrete release agent has good lubrication efficiency, which can lower the friction between the formwork and concrete surface, decrease the resistance during pouring and boost the construction efficiency.
Good anti-adhesion efficiency: concrete release representatives can successfully prevent the formwork from bonding with the concrete area, steering clear of the formwork from damaging the concrete surface when dismantling the formwork.
Excellent waterproof efficiency: concrete release agent has good waterproof overall performance, which can successfully stop moisture from penetrating between the formwork and concrete, preventing 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 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 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 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 construction of a reinforced concrete structure, concrete release agents 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 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 covering 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 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 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 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 improve the construction efficiency and quality of the development project and provide a strong guarantee for the growth of the construction industry.
