What exactly is a concrete release agent?
A concrete release agent is actually a material put on the development template before the concrete is added in order that the template will not stick to to the concrete surface after flowing, isn’t easy to dismantle the mould or affects the end of the concrete surface. Its primary role inside the design and the concrete covering to create a motion picture that is going to be separated from the two can also be known as an remoteness agent.
A water-based release agent is an crucial ancillary within the release agent and can alter the water-based release agent stream and levelling; its primary characteristic is actually stability to microorganisms and enzymes, which can reduce the cost of raw materials. A water-based form release agent can be used in casts and goods functional processing additives; in the rubber, plastic, and Jinsu processing industry, manufacturing cast items aren’t just so as to let the cast release to boost productivity and extend the life of the form utilize. And can make the item clean, size qualified, and reduce the generation of scrap, that is an crucial supplementary vital to casts and items – Water-based Concrete Release Agent.
Concrete release agent plays an important role in modern building development; its principal role would be to create a layer of separation film between the template and the concrete surface to ensure that the template does not adhere to the concrete covering in order that it is simpler to dismantle the form following pouring and to maintain the end of the concrete area. Here, we will present the sorts, features, usage and program of concrete release agent in more detail.
Types of concrete release agent
Concrete release agents can be divided into many kinds according to different category techniques, and the common category strategies are as follows:
- According to the the scope of use: it can be divided into concrete release agent for building, concrete release agent for bridges, concrete emission agent for tunnels and etc.
- According to the composition of: it can be divided into water-based concrete release brokers, oil-based concrete release representatives, silicone oil concrete release brokers, etc.
- According to the utilization effect: it can be divided into ordinary concrete release agents, simple to remove concrete release agents, high-gloss concrete release agents and etc.
Features of Concrete release agent
A concrete release agent is additionally known as a concrete isolation agent or mould release lubricant. It is a kind of material coated on the inner wall of the formwork to play the function of lubricating and isolation so that the concrete may be easily detached from the formwork when taking down the formwork, and the condition of the concrete can be kept intact and undamaged. Compared with the traditional release material motor oil or waste motor oil, the release agent has the positive aspects of simple release, no pollution of the concrete area, no corrosion of the template, effortless to paint, low price and so on. However, not all sorts of concrete release representatives with a selection of supplies made of templates are suitable for different components of the template and different construction 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 following features:
Good remoteness efficiency: concrete release agent can form a dense isolation film between the formwork and the concrete area, efficiently avoiding the formwork from bonding with the concrete surface and facilitating the dismantling.
Good lubrication efficiency: concrete release agent has good lubrication performance, which can lower the friction between the formwork and concrete surface, lower the resistance during pouring and improve the construction productivity.
Excellent anti-adhesion overall performance: concrete release representatives can efficiently prevent the formwork from bonding with the concrete covering, steering clear of the formwork from damaging the concrete covering when taking down the formwork.
Excellent waterproof overall performance: concrete release agent has good waterproof performance, which can effectively prevent 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.
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 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 surface 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 taking apart.
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 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 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 area 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 construction projects.
In conclusion, concrete release agent, as an important 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 boost the construction efficiency and quality of the building project and provide a strong guarantee for the growth of the building industry.
