What is actually a concrete release agent?
A concrete release agent is actually a material applied to the construction template just before the concrete is poured so that the template will not stick to the concrete surface following flowing, isn’t effortless to take down the mould or affects the complete of the concrete area. Its main role inside the template and the concrete surface to form a motion picture that will be separated from the two is also referred to as an remoteness agent.
A water-based release agent is an essential ancillary within the release agent and can change the water-based release agent circulation and levelling; its primary characteristic is definitely stability to microorganisms and enzymes, which can decrease the price of raw materials. A water-based cast release agent can be used in casts and products functional processing supplements; in the rubber, plastic, and Jinsu processing business, manufacturing mould goods are not just to be able to let the form release to boost productivity and prolong the life of the mould use. And can make the product clean, size qualified, and reduce the technology of scrap, that is an crucial additional vital to casts and goods – Water-based Concrete Release Agent.
Concrete release agent plays an important role inside modern building building; its main role is to form a layer of remoteness movie between the template and the concrete area in order that the template doesn’t stick to to the concrete covering so that it is much easier to dismantle the form after pouring and to maintain the finish of the concrete covering. Here, we will present the types, characteristics, usage and application of concrete release agent in more detail.
Kinds of concrete release agent
Concrete release representatives can be divided into several kinds according to different grouping techniques, and the common category methods are as follows:
- According to the scope of use: it can be divided into concrete release agent for construction, concrete release agent for bridges, concrete release agent for tunnels and so on.
- According to the composition: it can be divided into water-based concrete release representatives, oil-based concrete release representatives, silicone oil concrete release agents, etc.
- According to the utilization effect: it can be divided into ordinary concrete release brokers, simple to remove concrete release agents, high-gloss concrete release agents and and so forth.
Qualities of Concrete release agent
A concrete release agent is additionally known as a concrete separation agent or mould release lubricant. It is actually a type of substance coated on the inner wall of the formwork to play the part of lubricating and remoteness so that the concrete may be smoothly detached from the formwork when dismantling the formwork, and the condition of the concrete could be kept intact and undamaged. Compared with the traditional release materials 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 sorts of concrete release agents with a selection of materials made of templates are suitable for different components of the template and different building problems and finish requirements of the concrete must be selected for the suitable release agent in order to receive good results.
As an important construction auxiliary material, concrete release agent has the next qualities:
Good separation efficiency: concrete release agent can develop a dense isolation movie between the formwork and the concrete area, efficiently avoiding the formwork from bonding with the concrete area and facilitating the demolding.
Excellent lubrication overall performance: concrete release agent has good lubricating overall performance, which can reduce the rubbing between the formwork and concrete surface, lower the resistance during pouring and boost the construction efficiency.
Good anti-adhesion overall performance: concrete release agents can successfully prevent the formwork from bonding with the concrete area, preventing the formwork from damaging the concrete surface when taking down the formwork.
Great waterproof performance: concrete release agent has good waterproof performance, which can efficiently prevent moisture from penetrating between the formwork and concrete, preventing deformation of the formwork by moisture and improving 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 area.
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 area 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 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, preventing 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 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 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 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 boost the construction efficiency and quality of the construction project and provide a strong guarantee for the growth of the building industry.
