What is a concrete release agent?
A concrete release agent is actually a material placed on the building template before the concrete is put so the design doesn’t stick to the concrete surface after flowing, is just not simple to take apart the cast or affects the complete of the concrete covering. Its main role within the design and the concrete covering to create a motion picture that will be separated from the two can also be called an remoteness agent.
A water-based release agent is an crucial supplementary 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 reduce the cost of raw materials. A water-based cast release agent can be used in forms and items functional processing supplements; in the rubber, plastic, and Jinsu processing business, manufacturing form goods are not only to be able to let the cast release to improve productivity and extend the life of the form make use of. And can make the merchandise clear, size qualified, and lower the generation of scrap, which is an important supplementary vital to casts and items – Water-based Concrete Release Agent.
Concrete release agent plays an crucial role in modern building construction; its primary role is always to create a layer of separation movie between the template and the concrete covering to ensure that the template doesn’t stick to to the concrete surface to ensure that it is much easier to take apart the cast following pouring and to maintain the complete of the concrete covering. Here, we will introduce the sorts, features, usage and program of concrete release agent in detail.
Sorts of concrete release agent
Concrete release brokers can be divided into several kinds in accordance with different category techniques, and the frequent classification methods 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 release agent for tunnels and and so forth.
- According to the composition of: it can be divided into water-based concrete release representatives, oil-based concrete release brokers, silicone oil concrete release brokers, etc.
- According to the utilization effect: it can be divided into ordinary concrete release representatives, easy-to-remove concrete release representatives, high-gloss concrete release agents and so on.
Features of Concrete release agent
A concrete release agent is additionally called a concrete separation agent or mould release lubricant. It is actually a kind of substance coated on the inner wall of the formwork to play the role of lubricating and separation in order that the concrete could be effortlessly detached from the formwork when taking down the formwork, and the shape 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 benefits of easy release, no pollution of the concrete surface, no corrosion of the template, simple to paint, low value and and so forth. However, not all types of concrete release brokers with a variety of supplies made of templates are suitable for different materials of the template and different development circumstances 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 next characteristics:
Good separation performance: concrete release agent can create a dense isolation movie between the formwork and the concrete surface, successfully preventing the formwork from bonding with the concrete covering and facilitating the removing.
Great lubrication efficiency: concrete release agent has good lubrication performance, which can decrease the friction between the formwork and concrete surface, lower the resistance during pouring and boost the construction productivity.
Excellent anti-adhesion overall performance: concrete release agents can effectively avoid the formwork from bonding with the concrete area, steering clear of the formwork from damaging the concrete surface when dismantling the formwork.
Great waterproof overall performance: concrete release agent has good waterproof efficiency, which can successfully stop moisture from penetrating between the formwork and concrete, steering clear of deformation of the formwork by moisture and enhancing the service life of the formwork.
Simple 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 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 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 development 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 area, 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 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 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 construction projects.
In conclusion, concrete release agent, as an important construction auxiliary material, plays an indispensable role in modern construction projects. By choosing the right kind, the correct use method and a reasonable application field, can effectively improve the construction efficiency and quality of the building project and provide a strong guarantee for the growth of the development industry.
