What is actually a concrete release agent?
A concrete release agent is actually a compound put on the building design before the concrete is added in order that the template will not stick to the concrete covering after putting, is not easy to take apart the form or impacts the finish of the concrete surface. Its primary role within the template and the concrete covering to develop a motion picture that will be separated from the two is additionally known as an remoteness agent.
A water-based release agent is an crucial ancillary inside the release agent and can alter the water-based release agent flow and levelling; its primary attribute is definitely stability to microorganisms and enzymes, which can decrease the price of raw materials. A water-based mould release agent can be used in forms and goods functional processing additives; in the rubber, plastic, and Jinsu processing market, manufacturing mould goods are not only so as to let the mould release to enhance productivity and extend the life of the mould utilize. And can make the item clean, size qualified, and decrease the creation of scrap, which can be an crucial additional important to moulds and products – Water-based Concrete Release Agent.
Concrete release agent plays an crucial role in modern building construction; its principal role is always to create a layer of separation motion picture between the template and the concrete covering so that the design doesn’t adhere to the concrete area in order that it is easier to dismantle the cast after pouring and to maintain the complete of the concrete area. Here, we will introduce the types, qualities, usage and use of concrete release agent in detail.
Types of concrete release agent
Concrete release representatives can be divided into numerous types based on different classification methods, and the frequent category techniques are the subsequent:
- According to the opportunity of use: it can be divided into concrete release agent for construction, concrete release agent for bridges, concrete discharge agent for tunnels and etc.
- According to the the composition of: it can be divided into water-based concrete release representatives, petroleum-based concrete release representatives, silicone oil concrete release agents, etc.
- According to the use effect: it can be divided into ordinary concrete release agents, simple to remove concrete release brokers, high-gloss concrete release representatives and and so forth.
Qualities of Concrete release agent
A concrete release agent is additionally referred to as a concrete remoteness agent or mould release lubricant. It is actually a sort of material coated on the inner wall of the formwork to play the role of lubricating and separation to ensure that the concrete may be effortlessly detached from the formwork when dismantling the formwork, and the shape of the concrete may 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 area, no corrosion of the template, easy to paint, low value and so on. However, not all kinds of concrete release representatives with a array of components 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 important construction auxiliary material, concrete release agent has the subsequent qualities:
Good isolation efficiency: concrete release agent can create a dense remoteness film between the formwork and the concrete surface, effectively avoiding the formwork from bonding with the concrete surface and facilitating the demolding.
Excellent lubrication performance: concrete release agent has good lubricating overall performance, which can reduce the friction between the formwork and concrete surface, decrease the resistance during pouring and boost the construction efficiency.
Great anti-adhesion overall performance: concrete release agents can effectively avoid the formwork from bonding with the concrete covering, avoiding the formwork from damaging the concrete area when dismantling the formwork.
Excellent waterproof overall performance: concrete release agent has good waterproof overall performance, which can successfully prevent 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 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 area.
Demolding: Demolding can be carried out after the concrete reaches the strength of demolding. When taking apart 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 covering gradually. In case of tight bonding between the formwork and the concrete area, tools can be used appropriately to assist in the dismantling.
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 building 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, avoiding 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 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 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 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 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 building projects.
In conclusion, concrete release agent, as an important construction auxiliary material, plays an indispensable role in modern development projects. By choosing the right sort, 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 development of the development industry.
