What exactly is a concrete release agent?
A concrete release agent is actually a substance placed on the building template prior to the concrete is added in order that the design does not stick to to the concrete covering right after flowing, is just not effortless to take down the form or impacts the finish of the concrete covering. Its principal role inside the design and the concrete covering to create a movie that is going to be separated from the two can also be called an separation agent.
A water-based release agent is surely an crucial supplementary inside the release agent and can change the water-based release agent stream and levelling; its principal feature is stability to microorganisms and enzymes, which can lower the cost of raw materials. A water-based cast release agent is used in moulds and items functional processing ingredients; in the rubber, plastic, and Jinsu processing business, manufacturing mould products are not just to be able to let the mould release to boost productivity and prolong the life of the mould utilize. And can make the product thoroughly clean, size qualified, and lower the creation of scrap, that is an essential additional important to casts and items – concrete additive.
Concrete release agent plays an important role in modern building building; its principal role is always to create a layer of remoteness film between the template and the concrete covering so that the template will not adhere to the concrete surface to ensure that it is much easier to take apart the mould right after pouring and to maintain the finish of the concrete surface. Here, we will unveil the types, qualities, utilization and program of concrete release agent in detail.
Kinds of concrete release agent
Concrete release agents can be divided into many types in accordance with different category strategies, and the typical category strategies are the subsequent:
- According to the scope of use: it can be divided into concrete release agent for construction, concrete release agent for bridges, concrete discharge agent for tunnels and so on.
- According to the formula of: it can be divided into water-based concrete release agents, petroleum-based concrete release brokers, silicone oil concrete release representatives, etc.
- According to the the effect of use: it can be divided into ordinary concrete release brokers, simple to remove concrete release representatives, high-gloss concrete release representatives and and so forth.
Characteristics of Concrete release agent
A concrete release agent can also be referred to as a concrete remoteness agent or mould release lubricant. It is really a kind of substance coated on the inner wall of the formwork to play the role of lubrication and remoteness in order that the concrete can be smoothly detached from the formwork when taking down the formwork, and the condition of the concrete could be kept intact and undamaged. Compared with the conventional release materials motor oil or waste motor oil, the release agent has the advantages of easy release, no pollution of the concrete surface, no corrosion of the template, effortless to paint, low price and and so forth. However, not all kinds of concrete release brokers with a array of supplies made of templates are suitable for different supplies of the template and different construction circumstances 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 overall performance: concrete release agent can develop a dense isolation movie between the formwork and the concrete area, successfully avoiding the formwork from bonding with the concrete covering and facilitating the demolding.
Good lubrication overall performance: concrete release agent has good lubrication efficiency, which can lower the friction between the formwork and concrete area, decrease the resistance during pouring and improve the construction productivity.
Excellent anti-adhesion performance: concrete release representatives can successfully prevent the formwork from bonding with the concrete surface, avoiding the formwork from damaging the concrete surface when taking down the formwork.
Good waterproof efficiency: concrete release agent has good waterproof efficiency, which can efficiently stop moisture from penetrating between the formwork and concrete, avoiding deformation of the formwork by moisture and enhancing the service life of the formwork.
Effortless 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 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 area 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 area, tools can be used appropriately to assist in the taking down.
Clean up the template: after taking apart 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 construction of a reinforced concrete structure, concrete release representatives can be used for formwork isolation, preventing 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 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 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 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 essential construction auxiliary material, plays an indispensable role in modern development projects. By choosing the right kind, the correct use method and a reasonable application field, can effectively boost the construction efficiency and quality of the construction project and provide a strong guarantee for the growth of the building industry.
