What is a concrete release agent?
A concrete release agent is a compound applied to the construction design just before the concrete is put so the template does not stick to the concrete area after flowing, is just not easy to dismantle the cast or affects the complete of the concrete covering. Its primary role inside the template and the concrete covering to develop a movie that is going to be separated from the two is also known as an separation agent.
A water-based release agent is definitely an essential ancillary within the release agent and can alter the water-based release agent circulation and levelling; its main feature is stability to microorganisms and enzymes, which can reduce the expense of raw materials. A water-based form release agent can be used in moulds and products functional processing supplements; in the rubber, plastic, and Jinsu processing market, manufacturing mould goods are not just so as to let the mould release to boost productivity and prolong the life of the form make use of. And can make the product thoroughly clean, size qualified, and lower the generation of scrap, which can be an crucial supplementary vital to moulds and products – concrete release agent.
Concrete release agent plays an crucial role inside modern building building; its main role would be to create a layer of isolation movie between the template and the concrete area to ensure that the template doesn’t adhere to the concrete surface in order that it is easier to take apart the mould right after putting and to maintain the complete of the concrete covering. Here, we will unveil the kinds, features, usage and application of concrete release agent in detail.
Sorts of concrete release agent
Concrete release agents can be divided into several sorts according to different category methods, and the frequent classification methods are as follows:
- According to the the opportunity of use: it can be divided into concrete release agent for building, concrete release agent for bridges, concrete release agent for tunnels and so on.
- According to the the composition of: it can be divided into water-based concrete release representatives, oil-based concrete release representatives, silicone oil concrete release brokers, etc.
- According to the effect of use: it can be divided into ordinary concrete release brokers, simple to remove concrete release agents, high-gloss concrete release representatives and etc.
Characteristics of Concrete release agent
A concrete release agent can also be known as a concrete isolation agent or mould release lubricant. It is a sort of substance coated on the inner wall of the formwork to play the part of lubricating and remoteness to ensure that the concrete may be effortlessly detached from the formwork when dismantling the formwork, and the shape of the concrete could be kept intact and undamaged. Compared with the standard release materials motor oil or waste motor oil, the release agent has the benefits of effortless release, no pollution of the concrete surface, no corrosion of the template, easy to paint, low cost and so on. However, not all types of concrete release brokers with a selection of supplies made of templates are suitable for different materials of the template and different building problems and finish requirements of the concrete must be selected for the ideal release agent in order to receive good results.
As an crucial construction auxiliary material, concrete release agent has the next features:
Good separation efficiency: concrete release agent can form a dense remoteness film between the formwork and the concrete area, effectively avoiding the formwork from bonding with the concrete covering and facilitating the demolding.
Excellent lubrication overall performance: concrete release agent has good lubricating overall performance, which can decrease the chaffing between the formwork and concrete surface, lower the resistance during pouring and improve the construction productivity.
Great anti-adhesion efficiency: concrete release agents can successfully prevent the formwork from bonding with the concrete area, preventing the formwork from damaging the concrete surface when taking apart 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 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 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 down 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 area gradually. In case of tight bonding between the formwork and the concrete surface, 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 development projects, mainly including the following aspects:
Reinforced concrete structure: In the development of a reinforced concrete structure, concrete release representatives 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 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 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 boost 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 crucial 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 development industry.
