What is a concrete release agent?
A concrete release agent is a substance applied to the development template prior to the concrete is added so the template will not stick to the concrete surface right after putting, is not simple to dismantle the form or affects the complete of the concrete area. Its principal role within the template and the concrete surface to create a movie that will probably be separated from the two is also referred to as an isolation agent.
A water-based release agent is surely an essential ancillary inside the release agent and can modify the water-based release agent flow and levelling; its main feature is definitely stability to microorganisms and enzymes, which can reduce the price of raw materials. A water-based form release agent is utilized in moulds and items functional processing ingredients; in the rubber, plastic, and Jinsu processing market, manufacturing mould products are not just so as to let the cast release to boost productivity and extend the life of the mould make use of. And can make the product clear, size qualified, and lower the generation of scrap, which is an crucial additive vital to casts and goods – Water-based Concrete Release Agent.
Concrete release agent plays an essential role inside modern building construction; its main role would be to create a layer of separation movie between the template and the concrete surface in order that the template does not adhere to the concrete area so that it is easier to take down the form after flowing and to maintain the complete of the concrete surface. Here, we will introduce the sorts, qualities, use and application of concrete release agent in detail.
Kinds of concrete release agent
Concrete release representatives can be divided into many types based on different category strategies, and the common category methods are as follows:
- According to the scope 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 composition: it can be divided into water-based concrete release agents, petroleum-based concrete release representatives, silicone oil concrete release representatives, etc.
- According to the utilization effect: it can be divided into ordinary concrete release representatives, simple to remove concrete release brokers, high-gloss concrete release representatives and and so forth.
Characteristics of Concrete release agent
A concrete release agent can also be referred to as a concrete isolation agent or mould release lubricant. It is a type of compound coated on the inner wall of the formwork to play the part of lubricating and isolation so that the concrete could be effortlessly detached from the formwork when taking down the formwork, and the condition of the concrete could be kept intact and undamaged. Compared with the traditional release substance motor oil or waste motor oil, the release agent has the positive aspects of effortless release, no pollution of the concrete area, no corrosion of the template, simple to paint, low cost and and so forth. However, not all types of concrete release representatives with a variety of materials made of templates are suitable for different supplies of the template and different development circumstances and finish requirements of the concrete must be selected for the appropriate release agent in order to receive good results.
As an essential construction auxiliary material, concrete release agent has the following qualities:
Good isolation efficiency: concrete release agent can create a dense separation film between the formwork and the concrete area, effectively stopping the formwork from bonding with the concrete surface and facilitating the removing.
Great lubrication performance: concrete release agent has good lubricating overall performance, which can lower the friction between the formwork and concrete surface, lower the resistance during pouring and enhance the construction productivity.
Great anti-adhesion efficiency: concrete release representatives can effectively avoid 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 performance: concrete release agent has good waterproof efficiency, which can successfully prevent moisture from penetrating between the formwork and concrete, avoiding deformation of the formwork by moisture and increasing the service life of the formwork.
Easy 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 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 apart 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 area, tools can be used appropriately to assist in the dismantling.
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 brokers can be used for formwork isolation, preventing formwork from bonding with concrete and enhancing 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 covering, 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 surface and enhance 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 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 building projects. By choosing the right type, the correct use method and a reasonable application field, can effectively enhance the construction efficiency and quality of the development project and provide a strong guarantee for the advancement of the construction industry.
