What is actually a concrete release agent?
A concrete release agent is a compound placed on the development design just before the concrete is put so the template does not stick to to the concrete area following pouring, is just not simple to take down the form or affects the complete of the concrete area. Its principal role in the design and the concrete area to develop a movie that will probably be separated from the two is also known as an separation agent.
A water-based release agent is an important supplementary inside the release agent and can alter the water-based release agent circulation and levelling; its main feature is actually stability to microorganisms and enzymes, which can reduce the price of raw materials. A water-based mould release agent can be used in moulds and goods functional processing supplements; in the rubber, plastic, and Jinsu processing market, manufacturing mould goods are not just in order to let the mould release to enhance productivity and extend the life of the form utilize. And can make the item clear, size qualified, and decrease the technology of scrap, which is an essential additive important to forms and items – Water-based Concrete Release Agent.
Concrete release agent plays an crucial role within modern building development; its principal role is always to create a layer of isolation motion picture between the template and the concrete surface so that the template will not stick to to the concrete covering to ensure that it is easier to dismantle the mould following pouring and to maintain the complete of the concrete area. Here, we will present the kinds, characteristics, use and use of concrete release agent at length.
Sorts of concrete release agent
Concrete release agents can be divided into several sorts based on different classification strategies, and the common category methods are the subsequent:
- According to the opportunity of use: it can be divided into concrete release agent for development, concrete release agent for bridges, concrete launch agent for tunnels and so on.
- According to the composition of: it can be divided into water-based concrete release brokers, petroleum-based concrete release representatives, silicone oil concrete release representatives, etc.
- According to the utilization effect: it can be divided into ordinary concrete release brokers, an easy task to remove concrete release representatives, high-gloss concrete release agents and and so forth.
Characteristics of Concrete release agent
A concrete release agent is additionally called 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 remoteness to ensure that the concrete may be easily detached from the formwork when taking apart the formwork, and the condition of the concrete may be kept intact and undamaged. Compared with the conventional release material motor oil or waste motor oil, the release agent has the advantages of effortless release, no pollution of the concrete covering, no corrosion of the template, easy to paint, low value and etc. However, not all kinds 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 appropriate release agent in order to receive good results.
As an important construction auxiliary material, concrete release agent has the following characteristics:
Good separation efficiency: concrete release agent can create a dense remoteness movie between the formwork and the concrete covering, effectively avoiding the formwork from bonding with the concrete surface and facilitating the demolding.
Great lubrication performance: concrete release agent has good lubricating efficiency, which can decrease the friction between the formwork and concrete covering, lower the resistance during pouring and improve the construction efficiency.
Good anti-adhesion overall performance: concrete release representatives can successfully stop the formwork from bonding with the concrete surface, avoiding the formwork from damaging the concrete covering when taking down the formwork.
Excellent waterproof efficiency: concrete release agent has good waterproof performance, which can successfully prevent moisture from penetrating between the formwork and concrete, steering clear of deformation of the formwork by moisture and increasing the service life of the formwork.
Simple to use and safe: concrete release agent is simple 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 taking down 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 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 down 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 brokers can be used for formwork isolation, avoiding formwork from bonding with concrete and increasing 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 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 building projects.
In conclusion, concrete release agent, as an essential construction auxiliary material, plays an indispensable role in modern development 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 construction project and provide a strong guarantee for the development of the building industry.
