What exactly is a concrete release agent?
A concrete release agent is definitely a substance put on the construction template before the concrete is put so that the template does not stick to the concrete surface right after pouring, is just not effortless to take down the form or impacts the finish of the concrete surface. Its main role inside the template and the concrete area to create a motion picture that will be separated from the two is additionally referred to as an separation agent.
A water-based release agent is surely an essential auxiliary within the release agent and can change the water-based release agent stream and levelling; its principal characteristic is stability to microorganisms and enzymes, which can reduce the price of raw materials. A water-based form release agent can be used in forms and products functional processing supplements; in the rubber, plastic, and Jinsu processing business, manufacturing cast products aren’t just to be able to let the mould release to enhance productivity and prolong the life of the cast make use of. And can make the merchandise clean, size qualified, and lower the generation of scrap, that is an crucial supplementary vital to moulds and products – concrete additive.
Concrete release agent plays an crucial role within modern building building; its main role would be to form a layer of remoteness film between the design and the concrete covering so that the template will not stick to the concrete surface in order that it is simpler to dismantle the mould after putting and to maintain the finish of the concrete covering. Here, we will unveil the types, qualities, usage and application of concrete release agent at length.
Sorts of concrete release agent
Concrete release representatives can be divided into several sorts in accordance with different grouping methods, and the frequent grouping strategies are the subsequent:
- According to the opportunity of use: it can be divided into concrete release agent for development, concrete release agent for bridges, concrete release agent for tunnels and so on.
- According to the the composition: it can be divided into water-based concrete release brokers, oil-based concrete release representatives, silicone oil concrete release representatives, etc.
- According to the utilization effect: it can be divided into ordinary concrete release brokers, easy-to-remove concrete release brokers, high-gloss concrete release brokers and etc.
Features of Concrete release agent
A concrete release agent can also be known as a concrete remoteness agent or mould release lubricant. It is really a kind of compound coated on the inner wall of the formwork to play the role of lubricating and isolation to ensure that the concrete can be effortlessly detached from the formwork when dismantling the formwork, and the condition of the concrete could be kept intact and undamaged. Compared with the standard release substance motor oil or waste motor oil, the release agent has the benefits of effortless release, no pollution of the concrete area, no corrosion of the template, easy to paint, low price and etc. However, not all types of concrete release brokers with a variety of supplies made of templates are suitable for different supplies of the template and different construction conditions and finish requirements of the concrete must be selected for the suitable 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 create a dense isolation motion picture between the formwork and the concrete area, efficiently stopping the formwork from bonding with the concrete covering and facilitating the dismantling.
Great lubrication overall performance: concrete release agent has good lubricating overall performance, which can lower the rubbing between the formwork and concrete covering, reduce the resistance during pouring and boost the construction effectiveness.
Good anti-adhesion efficiency: concrete release representatives can effectively stop the formwork from bonding with the concrete surface, steering clear of the formwork from damaging the concrete covering when dismantling the formwork.
Excellent waterproof performance: concrete release agent has good waterproof performance, which can efficiently stop 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.
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 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 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 development projects, mainly including the following aspects:
Reinforced concrete structure: In the building of a reinforced concrete structure, concrete release brokers 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 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 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 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 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 important 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 enhance the construction efficiency and quality of the development project and provide a strong guarantee for the growth of the development industry.
