What is a concrete release agent?
A concrete release agent is a compound put on the construction template just before the concrete is poured in order that the template doesn’t stick to the concrete surface following flowing, isn’t simple to take apart the mould or affects the end of the concrete surface. Its main role in the template and the concrete area to develop a motion picture that will probably be separated from the two can also be referred to as an isolation agent.
A water-based release agent is definitely an important ancillary in the release agent and can modify the water-based release agent circulation and levelling; its principal feature is definitely stability to microorganisms and enzymes, which can decrease the price of raw materials. A water-based cast release agent is utilized in moulds and items functional processing ingredients; in the rubber, plastic, and Jinsu processing market, manufacturing cast products aren’t just so as to let the cast release to improve productivity and extend the life of the cast make use of. And can make the product clear, size qualified, and reduce the generation of scrap, which is an essential additive important to moulds and products – Water-based Concrete Release Agent.
Concrete release agent plays an essential role in modern building development; its primary role would be to form a layer of isolation movie between the template and the concrete surface in order that the design will not stick to to the concrete covering so that it is simpler to take apart the cast following flowing and to maintain the end of the concrete surface. Here, we will introduce 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 many kinds in accordance with different classification methods, and the common grouping strategies are the following:
- According to the the scope of use: it can be divided into concrete release agent for building, concrete release agent for bridges, concrete launch agent for tunnels and so on.
- According to the formula of: it can be divided into water-based concrete release agents, oil-based concrete release brokers, silicone oil concrete release agents, etc.
- According to the effect of use: it can be divided into ordinary concrete release representatives, easy-to-remove concrete release agents, high-gloss concrete release agents and etc.
Features of Concrete release agent
A concrete release agent is also referred to as a concrete isolation agent or mould release lubricant. It is really a sort of material coated on the inner wall of the formwork to play the role of lubricating and remoteness to ensure that the concrete may be smoothly detached from the formwork when taking apart the formwork, and the form of the concrete may be kept intact and undamaged. Compared with the traditional release materials motor oil or waste motor oil, the release agent has the advantages of effortless release, no pollution of the concrete covering, no corrosion of the template, effortless to paint, low price and and so forth. However, not all types of concrete release agents with a selection of supplies made of templates are suitable for different materials of the template and different development problems and finish requirements of the concrete must be selected for the suitable release agent in order to receive good results.
As an important construction auxiliary material, concrete release agent has the following characteristics:
Good remoteness efficiency: concrete release agent can form a dense separation film between the formwork and the concrete area, efficiently preventing the formwork from bonding with the concrete surface and facilitating the demolding.
Great lubrication efficiency: concrete release agent has good lubrication performance, which can lower the rubbing between the formwork and concrete covering, decrease the resistance during pouring and enhance the construction efficiency.
Good anti-adhesion overall performance: concrete release representatives can efficiently prevent the formwork from bonding with the concrete covering, steering clear of the formwork from damaging the concrete surface when taking apart the formwork.
Great waterproof efficiency: concrete release agent has good waterproof performance, which can successfully avoid 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 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 covering 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 covering, tools can be used appropriately to assist in the taking down.
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 construction 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 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 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 improve 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 enhance the construction efficiency and quality of the development project and provide a strong guarantee for the growth of the building industry.
