What is a concrete release agent?
A concrete release agent is actually a substance placed on the building design just before the concrete is put so that the design will not stick to to the concrete surface after putting, is just not simple to take apart the form or affects the complete of the concrete surface. Its main role within the template and the concrete area to create a film that is going to be separated from the two is also referred to as an isolation agent.
A water-based release agent is surely an crucial ancillary inside the release agent and can alter the water-based release agent flow and levelling; its principal characteristic 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 items functional processing supplements; in the rubber, plastic, and Jinsu processing business, manufacturing form items are not only so as to let the cast release to enhance productivity and extend the life of the mould use. And can make the merchandise clear, size qualified, and lower the generation of scrap, that is an essential additional important to casts and goods – concrete release agent.
Concrete release agent plays an crucial role inside modern building building; its principal role is always to form a layer of isolation motion picture between the template and the concrete area in order that the design doesn’t stick to to the concrete area to ensure that it is simpler to take down the cast right after pouring and to maintain the complete of the concrete area. Here, we will present the kinds, characteristics, usage and use of concrete release agent in more detail.
Sorts of concrete release agent
Concrete release brokers can be divided into numerous kinds in accordance with different category strategies, and the common category techniques are the subsequent:
- According to the scope of use: it can be divided into concrete release agent for building, concrete release agent for bridges, concrete discharge agent for tunnels and and so forth.
- According to the the composition: it can be divided into water-based concrete release brokers, oil-based concrete release agents, silicone oil concrete release representatives, etc.
- According to the utilization effect: it can be divided into ordinary concrete release brokers, easy-to-remove concrete release representatives, high-gloss concrete release representatives and and so forth.
Qualities of Concrete release agent
A concrete release agent can also be referred to as a concrete remoteness agent or mould release lubricant. It is actually a sort of substance coated on the inner wall of the formwork to play the function of lubricating and remoteness in order that the concrete can be easily detached from the formwork when taking down the formwork, and the form of the concrete can be kept intact and undamaged. Compared with the standard release substance motor oil or waste motor oil, the release agent has the benefits of simple release, no pollution of the concrete surface, no corrosion of the template, easy to paint, low price and so on. However, not all sorts of concrete release representatives with a selection of materials made of templates are suitable for different supplies of the template and different building circumstances 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 subsequent features:
Good separation performance: concrete release agent can develop a dense isolation movie between the formwork and the concrete surface, successfully avoiding the formwork from bonding with the concrete covering and facilitating the dismantling.
Good lubrication overall performance: concrete release agent has good lubrication overall performance, which can reduce the friction between the formwork and concrete surface, reduce the resistance during pouring and enhance the construction efficiency.
Good anti-adhesion efficiency: concrete release agents can effectively prevent the formwork from bonding with the concrete surface, steering clear of the formwork from damaging the concrete surface when taking down the formwork.
Excellent waterproof efficiency: concrete release agent has good waterproof overall performance, which can effectively avoid moisture from penetrating between the formwork and concrete, avoiding deformation of the formwork by moisture and increasing the service life of the formwork.
Simple 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 area.
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 area 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 surface, 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 building 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, 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 improve 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 development projects.
In conclusion, concrete release agent, as an crucial construction auxiliary material, plays an indispensable role in modern development projects. By choosing the right sort, the correct use method and a reasonable application field, can effectively enhance the construction efficiency and quality of the construction project and provide a strong guarantee for the development of the construction industry.
