What exactly is a concrete release agent?
A concrete release agent is actually a substance placed on the construction design before the concrete is put so that the template doesn’t adhere to the concrete area after flowing, isn’t simple to dismantle the cast or affects the end of the concrete area. Its primary role within the template and the concrete covering to form a film that is going to be separated from the two is additionally called an remoteness agent.
A water-based release agent is surely an essential supplementary within the release agent and can change the water-based release agent flow and levelling; its principal attribute is stability to microorganisms and enzymes, which can reduce the price of raw materials. A water-based cast release agent can be used in forms and items functional processing additives; in the rubber, plastic, and Jinsu processing market, manufacturing form goods are not only in order to let the form release to boost productivity and extend the life of the mould utilize. And can make the product thoroughly clean, size qualified, and decrease the technology of scrap, which can be an important additive essential to moulds and products – concrete release agent.
Concrete release agent plays an important role inside modern building building; its main role is always to develop a layer of separation film between the template and the concrete covering in order that the design will not adhere to the concrete surface to ensure that it is easier to dismantle the cast right after putting and to maintain the complete of the concrete covering. Here, we will present the sorts, qualities, use and application of concrete release agent at length.
Types of concrete release agent
Concrete release agents can be divided into numerous kinds according to different grouping methods, and the frequent classification methods are as follows:
- According to the scope of use: it can be divided into concrete release agent for development, concrete release agent for bridges, concrete launch agent for tunnels and etc.
- According to the formula of: it can be divided into water-based concrete release agents, oil-based concrete release representatives, silicone oil concrete release representatives, etc.
- According to the effect of use: it can be divided into ordinary concrete release agents, easy-to-remove concrete release brokers, high-gloss concrete release representatives and etc.
Qualities of Concrete release agent
A concrete release agent is also known as a concrete isolation agent or mould release lubricant. It is actually a type of material coated on the inner wall of the formwork to play the part of lubricating and isolation so that the concrete can be smoothly detached from the formwork when dismantling the formwork, and the form of the concrete may be kept intact and undamaged. Compared with the standard release substance motor oil or waste motor oil, the release agent has the benefits of easy release, no pollution of the concrete covering, no corrosion of the template, simple to paint, low price and and so forth. However, not all sorts of concrete release agents with a variety of components made of templates are suitable for different components of the template and different development 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 next qualities:
Good isolation overall performance: concrete release agent can create a dense separation film between the formwork and the concrete surface, successfully preventing the formwork from bonding with the concrete surface and facilitating the dismantling.
Great lubrication performance: concrete release agent has good lubricating overall performance, which can decrease the chaffing between the formwork and concrete area, decrease the resistance during pouring and enhance the construction effectiveness.
Excellent anti-adhesion overall performance: concrete release agents can successfully avoid the formwork from bonding with the concrete surface, preventing the formwork from damaging the concrete covering when dismantling the formwork.
Excellent waterproof 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 improving the service life of the formwork.
Effortless 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 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 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 building of a reinforced concrete structure, concrete release brokers can be used for formwork isolation, stopping 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 surface, 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 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 construction projects.
In conclusion, concrete release agent, as an essential construction auxiliary material, plays an indispensable role in modern construction projects. By choosing the right kind, the correct use method and a reasonable application field, can effectively improve the construction efficiency and quality of the development project and provide a strong guarantee for the development of the building industry.
