What exactly is a concrete release agent?
A concrete release agent is definitely a compound put on the construction design prior to the concrete is added so the template doesn’t adhere to the concrete covering following putting, isn’t simple to take apart the mould or affects the finish of the concrete area. Its primary role in the design and the concrete surface to form a motion picture that will be separated from the two is also referred to as an separation agent.
A water-based release agent is definitely an essential ancillary inside the release agent and can modify the water-based release agent flow and levelling; its principal characteristic is actually 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 goods functional processing supplements; in the rubber, plastic, and Jinsu processing industry, manufacturing mould items aren’t just to be able to let the mould release to enhance productivity and lengthen the life of the form utilize. And can make the item thoroughly clean, size qualified, and reduce the creation of scrap, which can be an important supplementary important to moulds and items – concrete release agent.
Concrete release agent plays an crucial role in modern building building; its main role is always to create a layer of isolation film between the design and the concrete area in order that the template will not stick to the concrete area to ensure that it is simpler to take down the mould after pouring and to maintain the finish of the concrete surface. Here, we will present the sorts, characteristics, usage and program of concrete release agent in detail.
Types of concrete release agent
Concrete release brokers can be divided into many kinds in accordance with different grouping methods, and the typical category strategies are the following:
- According to the scope of use: it can be divided into concrete release agent for development, concrete release agent for bridges, concrete emission agent for tunnels and so on.
- According to the the formula of: it can be divided into water-based concrete release representatives, oil-based concrete release brokers, silicone oil concrete release agents, etc.
- According to the use effect: it can be divided into ordinary concrete release agents, easy-to-remove concrete release agents, high-gloss concrete release agents and so on.
Features of Concrete release agent
A concrete release agent is also known as a concrete isolation agent or mould release lubricant. It is really a sort of compound coated on the inner wall of the formwork to play the role of lubrication and isolation in order that the concrete can be smoothly detached from the formwork when dismantling the formwork, and the shape of the concrete can be kept intact and undamaged. Compared with the conventional release materials motor oil or waste motor oil, the release agent has the positive aspects of effortless release, no pollution of the concrete covering, no corrosion of the template, effortless to paint, low value and etc. However, not all sorts of concrete release representatives with a array of components made of templates are suitable for different components of the template and different building circumstances and finish requirements of the concrete must be selected for the suitable release agent in order to receive good results.
As an crucial construction auxiliary material, concrete release agent has the subsequent characteristics:
Good remoteness performance: concrete release agent can develop a dense separation film between the formwork and the concrete area, successfully avoiding the formwork from bonding with the concrete area and facilitating the demolding.
Good lubrication performance: concrete release agent has good lubricating efficiency, which can lower the friction between the formwork and concrete covering, lower the resistance during pouring and boost the construction effectiveness.
Great anti-adhesion performance: concrete release agents can successfully prevent the formwork from bonding with the concrete covering, avoiding the formwork from damaging the concrete area when taking down the formwork.
Excellent waterproof overall performance: concrete release agent has good waterproof overall performance, which can efficiently prevent moisture from penetrating between the formwork and concrete, steering clear of deformation of the formwork by moisture and improving 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 surface.
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 covering 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 covering, tools can be used appropriately to assist in the dismantling.
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 representatives can be used for formwork isolation, avoiding formwork from bonding with concrete and enhancing 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 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 development projects.
In conclusion, concrete release agent, as an essential 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 building project and provide a strong guarantee for the development of the development industry.
